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  - This paper presents the 3D printing technology for various textile materials. The application of this technology is vital in manufacturing various clothing items, primarily for specific purposes: hikers, firefighters, soldiers, and athletes. The installation of sensors, life function parameters monitoring and the usage of the new materials are the basis for the future development of the textile industry. Today, thermoplastic and textile materials are increasingly used in practice. Polylactic Acid (PLA) thermoplastic materials were used in the paper - in spool, Polyvinyl Chloride (PVC) and Nylon (in strips); while from textile materials, polyester, viscose and silk in the form of finished fabrics were considered. The technology of preparation of textile fibres for 3D printing using laser is shown. This technology makes it easier to combine textiles and molten filament. The pros and cons of joining different materials are discussed. Further research would go in the direction of making constructive solutions and testing the mechanical properties of various textile-polymer composites.

AB  - The review of non-destructive testing of pressure vessel for compressed air is given, as well as the assessment and analysis of defects on the integrity of the vessel itself. The focus here is on welded joints, as the most critical areas in pressure vessels, especially if thickness is large, like in the case considered here (50 mm), cylindrical air storage vessels made of HSLA steel. Toward this end conventional NDT methods, such as UT and Radiography are used in the first phase of this research, providing valuable data for structural integrity assessment based on detected unacceptable defects in welded joints. Anyhow, since few unacceptable defects were found by conventional UT, there was a need to use advanced NDT UT methods, such as Phased Array Ultrasonic Testing (PAUT), to evaluate defect position and size more precisely. In this way risk of failure can be assessed more reliable, which is of utmost importance for pressure vessel where probability of failure is low, but the consequence of failure is potentially catastrophic, like in the case considered here.
