AB  - The fuel-NOx emissions during the conversion of carbon-based feedstock into energy and
chemicals are on a global level in focus last decades due to environmental issues. The emission
of nitrogen oxides is recognized among the other pollutants, as one of the key environmental
problems related to energy production by various types of feedstocks. In this paper,
the effect of fuel-based nitrogen delivery on the development of NOx precursors (HCN and
NH3) during the devolatilization process of properly selected samples (coal, sawdust, wheat
straw, and ground coffee waste) has been examined. TG-DTG thermal analysis techniques,
coupled with mass spectrometry (MS) were used for the assessment of nitrogen distribution
for HCN and NH3 gases, as intermediate species during feedstocks devolatilization, which
directly influences the NOx emission during thermochemical conversion processes (pyrolysis
and combustion). The mass balance of nitrogen together with performed EGA (evolved
gas analysis), and the distribution of nitrogen between volatiles and formed char were also
determined. The obtained data for investigated samples could be exploited for further thermochemical
process optimization, in regard to NOx emissions. The presented results could
be used as the experimentally determined input parameters for the mathematical modeling
of indicated processes, and with further analysis can be transferred to large-scale industrial
plant applications.

AB  - The pyrolysis process of two low-rank coals (lignite Kostolac and Kolubara), and two waste
materials (spent coffee ground and tyre rubber granulate) as well as their blends, have been
examined by preliminary thermogravimetric analysis. Thermal decomposition experiments were
performed in an N2 atmosphere on raw (pyrolysis) and blend (co-pyrolysis) samples at heating
rates of 10, 15, and 20 K min-1. The lignite-waste blend was created in the following mass
percentage ratios 90:10, 80:20, and 70:30. Based on obtained experimental data, the strong
interactions were identified between the examined lignite and waste materials during copyrolysis,
indicating the presence of a positive synergistic effect. The characteristics of the raw
waste sample and the heating rate were recognized as two key parameters that influenced the
synergy result with lignite sample, in lignite-spent coffee ground blends. For lignite-waste rubber
granulate blends, the blending ratio is critical for beneficial synergistic effect (ratios of waste
rubber granulate with lignite less than 30% are preferred). The probable synergistic mechanisms
were further explained using performed kinetic analysis by varying the effective activation energy
with temperature and conversion. In addition, the influence of micro-scale condition
characteristics such as heating rate (as the experimental regulatory factor) on the magnitude
response of synergistic effect during co-pyrolysis was also investigated in this work.

AB  - In recent years, deep eutectic solvents (DESs) have attracted considerable attention, and they have been applied in many fields, such as dissolution and separation, electrochemistry, materials preparation, reaction, and catalysis. In this paper, a detailed thermal decomposition mechanism of DES-type II (consisting choline chloride (ChCl) and magnesium chloride hexahydrate (MgCl2·6H2O) in a molar ratio 2:1 (MgCl2·6H2O-[Ch]Cl)) was explained, using thermal analysis techniques. Physicochemical clarification of overall thermal decomposition mechanism and the influence of enthalpy–entropy compensation (EEC) on reactions mechanism emerging are presented for the first time, in favor of this DES type. In the kinetic analysis of the decomposition process, two approaches were used: model-free (inverse) and model-based (direct) methods. It was found that thermodynamic principles in the form of EEC are the source of kinetic compensation effect (KCE) during MgCl2·6H2O-[Ch]Cl thermal decomposition, as a consequence of the effects of molecular interactions. Key phenomenon in the complex multiple step process represents a parallel dehydration steps of MgCl2·6H2O in DES, leading to formation of intermediates, such as [MgCl1(H2O)5]1+ and [MgCl2(H2O)4]. It was established that formation of final products (Mg(OH)2 and MgOHCl) requires a higher expenditure of energy to overcome a high potential barrier, where reaction system compensates this energy via hydrogen bonding disruption. This was confirmed by the identification of a specific ‘oscillator’, flagged as Hsingle bondOsingle bondH···Cl hydrogen bond donating system of the energy (“heat bath”). All kinetic parameters and mechanisms of individual reaction steps were confirmed by numerical optimization of the process and modulated dynamic predictions.

AB  - This work provides insight into possibilities of maximum utilization of C3-C4 energy crops for thermo-chemical conversion (slow pyrolysis) into high value biochemicals, platform chemicals, drop-in fuels and combustible gases, using coupled kinetic and thermodynamic analyses. In order to examine the kinetics of decomposition of lignocellulosic components, model-free and model-based methods faded from thermal analysis data were used. Thermodynamic compensation was used for explicatory of entropy controlled process, where conformational changes and chemical exchange directly affect the type and distribution of obtained pyrolytic products. It was shown that external variable (i.e. the heating rate/temperature) does not change either an entire reaction mechanism (mechanistic nature of MG and AD pyrolyses) or transition state, but it changes activation enthalpy and activation entropy which lead to differences in terms of heat energy consumption, pyrolysis favorability and thus rates of generation of activated complex among feedstocks. To investigate the interplay of catalysts (present in feedstocks as minerals) and reactants, selective energy transfer (SET) model was applied. The model showed an activity of catalyst with different outputs towards two reactants, lignin part of the structure in MG and 1,8-cineole in AD. It was shown that AD is more convenient for thermal conversion than MG, regarding to lower transformation energy requirement, higher reactivity, as well as much faster accumulation of products.

AB  - The actual paper analyses the performance of different energy crop biomasses, Miscanthus x giganteus Greef et Deu (EC-1) and Arundo donax L. (EC-2) stems, during slow pyrolysis process monitored by simultaneous TG-DTG-MS techniques, through chemical exergy analysis. In addition to considering the physical and chemical characteristics of given feedstocks for their efficient thermo-chemical conversion into pyrolytic gas, in this study, a theoretical simulation for their implementation use in the gasification process was also performed. The performed thermodynamic study with detailed exergy analysis showed that the large contribution of exergy in syngas components such as CO and H2 originates primarily from cellulose pyrolysis of EC-1, while large exergy contribution in syngas component as CH4 originates from lignin pyrolysis of EC-2. It was founded that the exergy efficiency of syngas for EC-1 equals 19.04%, which is lower than the exergy efficiency of syngas for EC-2 (20.46%), as a result of higher ash content in EC-1. Also, it was reported that higher carbon (C) and hydrogen (H) contents present in the EC-2 sample generate higher gaseous energy and exergy values, i.e. the increment of exergy efficiency of syngas, by both approaches (pyrolysis and gasification exergy analysis), but results in a lower biomass chemical exergy (18.28 MJ kg−1). The methodology applied to the gasification process was shown a higher exergy efficiency for EC-2 (∼36 – 42%) than for EC-1 (∼33 – 39%), dependant on the equivalence ratio (ER).

AB  - In this work, the thermal decomposition process of coal bottom ash (collected after lignite
combustion in coal-fired power plant “Kostolac B” (TEKO-B), Serbia) was investigated, using
simultaneous TG (thermogravimetry) – DTG (derivative thermogravimetry) techniques
in an inert (Ar) atmosphere, at various heating rates (10.3, 20.9 and 32.1 K/min). In addition
to thermal characterization of the sample, the chemical composition and naturally occurred
radionuclides were also determined. Using the model-free (isoconversional) (by Friedman
(FR), Kissinger-Akahira-Sunose (KAS), Ozawa-Flynn-Wall (OFW) and Vyazovkin (VY)
methods) analysis, the complex kinetic nature of the process was successfully resolved. The
conducted numerical optimization of the process (using non-linear least square optimization)
had confirmed accuracy and reliability of estimated kinetic parameters. Model-based
(model-fitting) kinetic analysis showed the existence of a complex reaction scheme, over
two consecutive reactions steps and one single-stage reaction step, via mechanism order An,
F2, Fn, R3, Cnm (through n-dimensional nucleation/growth, chemical reactions, and n-th
order and m-power with autocatalysis mechanisms). Through physicochemical interpretation
of mechanism scheme, an assessment of recovery of valuable metals and metal oxides was
performed, by analysing the concentration of reaction species in a function of temperature of
individual steps. Likewise, the influence of certain precursor involved in decomposition process
as catalyst (in order to increase the yield of targeted product) was also inspected. Finally,
the simulation of actual process using the results obtained from applied methods/models was
performed, through application of modulated dynamic (MD) prediction.

radionuclides were also determined. Using the model-free (isoconversional) (by Friedman
(FR), Kissinger-Akahira-Sunose (KAS), Ozawa-Flynn-Wall (OFW) and Vyazovkin (VY)
methods) analysis, the complex kinetic nature of the process was successfully resolved. The
conducted numerical optimization of the process (using non-linear least square optimization)
had confirmed accuracy and reliability of estimated kinetic parameters. Model-based
(model-fitting) kinetic analysis showed the existence of a complex reaction scheme, over
two consecutive reactions steps and one single-stage reaction step, via mechanism order An,
F2, Fn, R3, Cnm (through n-dimensional nucleation/growth, chemical reactions, and n-th
order and m-power with autocatalysis mechanisms). Through physicochemical interpretation
of mechanism scheme, an assessment of recovery of valuable metals and metal oxides was
performed, by analysing the concentration of reaction species in a function of temperature of
individual steps. Likewise, the influence of certain precursor involved in decomposition process
as catalyst (in order to increase the yield of targeted product) was also inspected. Finally,
the simulation of actual process using the results obtained from applied methods/models was
performed, through application of modulated dynamic (MD) prediction.",

AB  - The aim of the article is to show the effects of the main gasifier operating parameters, such as
temperature, equivalence ratio, steam-to-fuel ratio, and gasification medium selection, on the
gasification performance of sewage sludge. Using the developed one-dimensional mathematical
thermodynamic equilibrium model for plasma and fluidized bed gasification, a comprehensive
parametric study is established. The model is based on the principle of the minimum of the Gibbs
function and uses only the ultimate and proximate analysis data as input to the model. The output
of the model gives the equilibrium composition of the gasses produced. When comparing different
gasification media, gasification with water steam gives a higher yield of H2 and CO in the syngas
produced. Further comparison of the two gasification processes in terms of energy consumption
is shown. The collected results can be useful in further analysis of the gasification processes, such
as energy and exergy analysis and kinetics.

AB  - Rapid industrialization together with issues over the depletion of traditional fuel supplies and environmental concerns have prompted researchers to look into developing an environmentally safe, renewable, costeffective, and long-term alternative energy source. Agriculture biomass is recognized as a potentially viable solution for utilization in the energy sector for achieving the sustainable and long-term transformation into energy and/or fuels. This type of biomass is generated in large amounts across the world, which may be converted to biofuels using a variety of methods. However, concerns related to the competing agricultural biomass applications need to be thoroughly examined taking into account both the short- and long-term actuality, and its impact on the soil by conversion to biofuels. According to common practice agricultural
biomass is dominantly used for biogas production due to its availability and simplicity of handling. Based on all mentioned the assessment of the most applicable raw materials for biogas production is essential for achieving
the sustainability criteria and promoting using biomass for energy production. In this paper, a theoretical approach was applied for experimentally obtained results of proximate and ultimate analysis of different biomass materials as a possible feedstock for biomass production. Based on data of proximate and ultimate analysis the theoretical biomechanical methane potential (TBMP) for considered samples was calculated. According to obtained results, agricultural biomass shows validity of use for biogas production considering the fulfillment of the raw material minimum quantity.

AB  - A pressurized drop tube furnace was used to study the pyrolysis behavior of bituminous and lignite coal at elevated pressure. Experiments were conducted at the pressure range from 1 to 10 atm in 100% N-2 or 100% CO2 atmosphere. The volatile yields, char morphology, swelling ratio, and pore structure were discussed in detail. The results show that the pressure, atmosphere and coal rank could effect on the volatile releasing and char evolution significantly. In N-2 atmosphere, the total volatile yields of YL and NM coal decrease as the pressure elevated, while in CO2 atmosphere, the mass release of NM coal increases at high pressure contributed by the reaction of CO2 with organic macromolecule inside the particles; different with bituminous coal, no significant swelling behavior is found with the increase of pressure; the BET surface area of YL char decreases as the pressure increases, while for lignite coal, in N-2 atmosphere and at high pressure, less macro pores are formed, which could contribute to the BET surface area. While in CO2 atmosphere, the CO2-macromocular organic reaction would promote the volatile releasing, and the BET surface area decreases significantly at high pressure.

AB  - The preliminary thermogravimetric studies of co-pyrolyzed low rank coals (lignites Kostolac and Kolubara) with waste materials (spent coffee ground and waste rubber granulate) in a form of blends have been performed. Thermal analysis measurements of blend samples were carried out in a nitrogen, atmosphere at three different heating rates of 10, 15, and 20 K per minute. The coal-waste blends were prepared in the percentage ratios of 90:10, 80:20, and 70:30. This work analyzed the synergy analysis for considered blends shown via descriptive parameters during co-pyrolysis process. According to the performed analysis, the presence of synergistic effect was identified, where strong interactions were also observed. For lignite-spent coffee ground blends, it was found that two factors which affect the synergy effect with coal are concentration of added biomass material and the heating rate. For lignite-tire rubber granulate blends, the blending ratio take on a decisive role for positive consequences of a synergistic effect (ratios below 30% of tire rubber granulate in coals are desirable). Also, in this work the influence of micro-scale condition parameters such as heating rate (as the experimental regulatory factor) was analyzed on the magnitude response of synergism during co-pyrolysis.

AB  - This work provides a novel methodology for the comprehensive evolved gas analysis
performed on a lab scale level during the biomass thermal degradation experimental tests.
TGA – MS coupling allows accurate correlation between molecular ion peak and fragment
peaks to the corresponding mass loss rates from DTG curves. Within the proposed semiquantitative
analysis, MS spectra were interpreted through the comparative analysis of
compound fragments and of the compound itself, where the single atomic mass unit was
identified by multiple compounds exhibition [1]. It was shown that by this procedure which
involves overlapping multiple curves supervising, the identification of gases in the volatiles
complex scheme becomes more simplified. The simplified scheme for the proposed
methodology with major steps necessary to be performed is presented in Figure 1. By setting up semi-quantitative formulas, easy and reliable calculations of gaseous
products yield and syngas energy capacities are possible to achieve. The obtained results by
proposed methodology for wheat straw sample is given in Table 1.

AB  - Thermal decomposition of hydrous volcanic glass occurs through the release of different water species under overlapping processes over wide temperature range. Its investigation is of practical interest since it constitutes integral processing part towards its valorization as source for the production of high-quality porous material for various applications. The study presents investigation of thermal decomposition of hydrous rhyolite through the non-isothermal solid-state kinetics approach. Rhyolite decomposition occurs through three partially overlapping processes, where loosely held and chemically bound water, as well as hydroxyl release at different temperature regions and through different mechanisms. The separation of overlapped thermal curves was done through peak deconvolution method using Frazier-Suzuki equation. Subsequently, the isoconversional (model-free) Friedman, generalized master-plots and Kissinger methods were applied for the determination of apparent activation energy (E-a), reaction model (f(a)) and pre-exponential factor (A) for each individual reaction step considered. Using the kinetic triplet values of each process, the kinetic rate equations were combined allowing precise simulation of the dehydration and dihydroxylation processes. A comparison of model results with thermogravimetric (TG) data, as well as data from the literature, showed the satisfactory accuracy of the model in the simulation of the process and the successful prediction of each water type fraction, during the process evolution. Spectroscopy techniques in UV-VIS and NIR (near infra-red) spectral ranges were applied to raw rhyolite and sample with different water content allowed calculation of color coordinates and its correlation with dehydration and dehydroxylation degrees, and also identification of water species.

AB  - The issue of accumulated seashell waste has been increasingly addressed in the studies of its applicability as a secondary source of calcium carbonate. In this work, the mechanism of the thermo-oxidative degradation of two types of mollusk shells (Dosinia exoleta-DE and oyster Ostrea edulis-OE) was investigated using simultaneous thermal analysis. Physicochemical characterization of raw and calcined materials was performed by XRD and SEM techniques. Results show that increasing powder particle size and heating rate affect the degradation of investigated shells differently and have a significant contribution to released quantities of CO2. It was proposed that the calcination rate of DE powders is determined by the strain-induced collapse of CO2-deficient calcite at its interface with crystalline CaO rods-like structure, with simultaneous expulsion of CO2. A much higher CO2 concentration was identified during the degradation of OE powders, favoring the carbonation reaction and, consequently, increasing the temperature and activation energy of the investigated reaction. Under elevated CO2 concentration, the CaO aggregation step is enhanced by slower reaction kinetics at lower temperatures since both CO2 desorption and structural transformations are probably hindered. The proposed mechanism leads to a meaningful correlation between thermodynamic quantities (enthalpy-entropy compensation) in the form of an iso-kinetic relationship.

AB  - The pyrolysis of [4-(hydroxymethyl)phenoxymethyl]polystyrene (Wang) resin was studied by dynamic simultaneous thermogravimetric analysis (TGA) and derivative thermogravimetry techniques. The studied resin is used as the most commonly polymer supports in the peptide synthesis. A developed experimental master plots (exp-MP) model is presented that can be used to describe in more detail the pyrolysis of the resin established upon 4-hydroxybenzyl alcohol (PHB) on polystyrene, occurring throughout TGA experiments. This model assumes that the Wang resin is pyrolyzed through three parallel independent reaction steps, whereby their separation was performed through deconvolution procedure of the complex conversion rate curves. The mechanistic nature of each stage of Wang resin pyrolysis was explained by applying a combination of kinetic models such as diffusion mechanism, random nucleation and subsequent growth and chemical reactions mechanisms. The kinetic triplet parameters obtained in the present paper were then compared with those available in the literature. Within this kinetic study, the fraction distribution analysis (via distributed reactivity model) was performed, enabling reliable prediction of liquid products produced during the pyrolysis of the solid support of the Wang resin.

AB  - Sustainable development and mitigation of the climate changes are one of the main challenges of the circular economy, while the use of food industry residues could make an important contribution in tackling these challenges. In order to improve energy efficiency aspects of the industry residue treatment, generally, the drying process as the first step of the entire processing chain should be further analyzed. Regarding this, a comprehensive kinetic study was performed to provide the detailed mechanism of moisture removal from base raw material. Industrial residues from apple juice production were used for isothermal thermogravimetric analysis in the air atmosphere at different temperatures. Based on experimental data, different kinetic models were applied to determine kinetic parameters and dominant conversion functions. The dependence of the activation energy evaluated by Friedman's isoconversional method on the conversion degree shows that the drying process is complex one. The mechanism of drying process and corresponding kinetic parameters were determined by multivariate nonlinear regression program (model-based analysis) and checked by modulated isothermal prediction (for quasi-isothermal conditions) and the isothermal prediction (for different isothermal conditions) tests. It was pointed out that temperature-dependent reaction step controlling overall mechanism represents releasing of CO2 which can suppress autocatalytic action of the ethylene, influencing the flavor and texture changes of the apple tissue. Obtained results can be used for prediction of the life-time of studied material, corresponding to selected temperatures and different conversion levels.

AB  - The presented paper deals with the influence of the heating rate on combustion characteristics (reactivity and reactivity evaluation, ignition index (D-i), burnout index (D-f), the combustion performance index (S), and the combustion stability index (R-W)) of the protective coronavirus face masks. Two types of commonly used face masks in different state (new and exploited) were investigated by TG-DTG analysis in an air atmosphere, directly coupled with mass spectrometry (MS). Based on the experimental results, the impact of ultimate and proximate analysis data on the evolved gas analysis (EGA) was discussed. Also, the derived values from thermo-analytical (TA) data were compared with the literature reports, related to individual constitutive face mask materials. According to the performed research, it was established that different maximal reaction rate values at various heating rates indicate the complex nature of coronavirus face mask thermo-oxidative degradation, which is stimulated with carbon oxidation reactions and volatile matter (VM) release. By detailed analysis of obtained TG-DTG profiles, it was established that process takes place through the multiple-step reaction pathways, due to many vigorous radical reactions, causes by polymers degradation. The performed research was done to evaluate the possible utilization of coronavirus waste to energy production and sustainable pandemic environmental risk reduction.

AB  - Pyrolytic tire (PT) chars were first produced from waste car tires (WCT) through carbonization process at 800 degrees C, for different retention times. Then, best PT-char sample by its physicochemical properties (WCT 800(1 h)) was further tested for its ability to adsorb Rhodamine B (RhB) dye from aqueous solutions. Structural characterization of synthesized material showed existence of graphene-based material, with average pore diameter of 22.8 nm and specific surface area of 55.8 m2.g- 1. Obtained carbon material meets specifications of commercial carbon black (CB). The yield of 33.6% of CB recovered has been achieved. Under the optimal conditions, 99.57% of RhB was removed. Adsorption of RhB obeys pseudo second-order model and Langmuir isotherm model. DFT (the density functional theory) was revealed that effective bonding of RhB onto WCT 800 originates from pi-electron interactions with aromatic moieties and chemical (or at least the electrostatic) interactions, between positive nitrogen and electron-rich surface groups.

AB  - With the increased popularity of using wood stoves for household heating in recent years, numerous experimental research projects have been launched with the goal of generating cleaner and more efficient stove designs. This work is focused on mathematical modeling of combustion process in low-power residential heating appliance (small-scale stove) fuelled by different wood pellets (WP1-Beech (hardwood) and WP2-Pine (softwood)). Kinetic model scheme that encompasses determination of Arrhenius parameters was proposed for applied Finite rate/Eddy Dissipation approach. Types of wood pellets have been combusted on the experimental stand which is equipped with a set of temperature sensors and exhaust analyzer. A comparison of results obtained from combustion in the heating unit has been performed to find relations between established kinetics of devolatilization for various wood pellets and to determine exhaust composition, arising from oxidation reactions. Numerical modeling using computational fluid dynamics (CFD) has been performed for the char and CO oxidations to supplement the experimental results. Due to limitations on installed stove such as poor design, air supply, fume extraction, or heat exchanger can lead to excessive CO emissions or lower energy efficiency. Outcomes show that it is crucial to minimize unused stove volume and to enhance gaseous mixing for reduction of CO emissions, while maintaining sufficiently high temperatures for supporting fast oxidation reactions. Results of comparisons of conducted analyses can be useful in areas related to process optimization and improvement of combustion and devolatilization reaction conditions in the small scale heating units.

Outcomes show that it is crucial to minimize unused stove volume and to enhance gaseous mixing for reduction of CO emissions, while maintaining sufficiently high temperatures for supporting fast oxidation reactions. Results of comparisons of conducted analyses can be useful in areas related to process optimization and improvement of combustion and devolatilization reaction conditions in the small scale heating units.",

AB  - Food wastes are generated massively across global food supply chains. Conventional treatments of food waste (e.g.,
landfilling and incineration) could cause environmental, economic and social problems. Valorization of food waste
into value-added chemicals is a more sustainable and cost-effective option. This paper investigates the slow pyrolysis
as an environmentally friendly and efficient way to thermo-chemically conversion of food waste into value-added
products. TGA-DTG study of slow pyrolysis of dried Goji berry pulp (GBP) samples was carried out at different
heating rates. To establish pyrolysis mechanism, two kinetic approaches were used for determination of kinetic
parameters: first, which involves using model-free methods and second, the use of iso-kinetic relationship analysis to
identify the low and high-temperature kinetic regimes during the chemical transformation of the investigated material.
It was shown that iso-kinetic temperature (363.79 °C) represents a transition from the low-kinetic regime (enzymatic
hydrolysis) to the high-kinetic regime (acid hydrolysis), which strongly depends on temperature i.e. applied heating
rate. Significant compensation between kinetic parameters is a consequence of a change in the mechanism of
glucosides’ bond cleavage.

AB  - The emission control from coal-fired power plants is on a global level in focus last decades due to environmental issues. The emission of nitrogen oxides is recognized among the other pollutants, as the key environmental problem related to energy production by the coal utilization. In this paper, the effect of fuel nitrogen delivery on the NOx precursors (HCN and NH3) during devolatilization processes of selected coal samples (with high content of nitrogen) has been examined. TG-DTG coupled with mass spectrometry (MS) experimental techniques was used for the assessment of nitrogen distribution for HCN and NH3 as intermediate species during coal devolatilization, which directly influences the emission of nitrogen oxides during the combustion process. Further by the establishment, the mass balance of nitrogen together with performed analysis of evolved gases, the distribution of nitrogen between volatiles and char could be also determined. The obtained data for particular coal samples could be exploited for further coal combustion process optimization in regard to NOx emissions, and can be used as the experimentally determined input parameters for mathematical modeling of the coal combustion process, in the large-scale coal-fired power plants.

AB  - Despite many advantages of the utilization of biomass as a renewable energy source, certain bottlenecks during biomass plant operation can be identified. Transport and collection of biomass as well as non-uniform material characteristics are issues related to decreasing efficiency of logistics and fuel manipulation which can also cause economic problems with biomass collection, transport, and storage. Since biomass is an especially reactive fuel, this has raised concerns over its safe handling and utilization. Fires, and sometimes explosions, are a risk during all stages of fuel production as well as during handling and utilization of the product. This paper presents a novel method for assessing ignition risk and provides a ranking of relative risk of ignition of biomass fuels. Tests within this method include physical and chemical properties of biomass, thermal analysis measurements, and the calculation procedure steps which were made using characteristic temperatures from thermogravimetry recordings. The results of thermogravimetry analysis were used for determination of tangent slope of the mass loss rate curves in devolatilization zone at considered heating rates for all tested samples. Linear interpolation of the data obtained by tangent slope analysis and used heating rates may provide unique straight line for each sample in the ignition testing. Thermogravimetry index of spontaneous ignition (TGspi) is obtained for all samples based on newly established formula. By varying gradient of linear dependence of self-heating coefficient against reference temperatures, mass and heat transfer limitations for various biomasses were discussed. The proposed method is accurate as well as relatively simple and quick, enabling determination of data necessary for design and application of appropriate measures to reduce fire and explosion hazard related to operation of biomass.

AB  - This paper provides in-depth knowledge about the evolved gas analysis interpretation via newly proposed semi-quantitative approach, arising from thermogravimetric analysis (TGA) - mass spectrometry (MS) coupled measurements, for studying pyrolysis behavior of three kinds of biomass waste materials (spent coffee grounds, beech sawdust and wheat straw). TGA - MS coupling allows accurate correlation between molecular ion peak and fragment peaks to the corresponding mass loss rates from derivative thermogravimetry curves. Within proposed semi-quantitative analysis, MS spectra were interpreted through the comparative analysis of compounds fragments and of the compound itself, where the single atomic mass unit was identified by multiple compounds exhibition. It was shown that by this procedure which involves overlapping multiple curves supervising, the identification of gases in volatiles complex scheme becomes more simplified. By setting up semi-quantitative formulas, easy and reliable calculations of gaseous products yield and syngas energy capacities are possible to achieve. The H-2/CO ratio derived from the proposed method for wood waste product (sawdust) is in an excellent agreement with H-2/CO ratio for sawdust syngas production, in fuel reactor for biomass gasification and H-2 production.

AB  - Alternative fuels are crucial for the decarbonisation of high-energy demanding processes. The utilisation of waste materials to produce alternative fuels is especially interesting since, the co-pyrolysis of waste plastics and biomass was lately introduced as promising method since the synergistic effect might enhance the product properties compared to those from individual pyrolysis. Furthermore, the utilisation of waste biomass, like sawdust, is interesting since it does not influence the sustainability of biomass consumption, and even more, it avoids the usage of raw feedstock. Thermogravimetric analysis is per -formed to determine the thermal degradation behaviour and kinetic parameters of investigated mixtures to find the most appropriate utilisation method. Co-pyrolysis was conducted for three mixtures with the following biomass/polyurethane ratios: 75-25%, 50-50%, 25-75%, over a temperature range of 30-800 degrees C, at three heating rates 5,10 and 20 degrees C/min, under an inert atmosphere. Obtained results were subjected to comprehensive kinetic analysis to determine effective activation energy using the iso-conversional model-free methods and provide a detailed analysis of the samples' thermal degradation process. This work aimed to identify the main thermal decomposition stages during co-pyrolysis of biomass and polyurethane mixtures and provide the mixture composition's influence on the considered thermochemical conversion process.
