The combustion reactivity of plane tree seeds (PTS) biomass feedstock was studied using
the thermogravimetry (TG). The effects of atmosphere (O2/Ar) and different oxygen concentrations
(O2:Ar = 20:80 % and O2:Ar = 50:50%) on the combustion characteristics were
investigated. The results indicate that oxygen concentration show effectiveness on combustion
of PTS. When combustion atmosphere changes from O2:Ar = 50:50% to O2:Ar = 20:80%
(reducing oxygen concentrations), the burnout temperature increases by 29.50 oC for tested
biomass and combustion process becoming more challenging. The obtained results demonstrate
the ease of ignition of investigated lignocellulosic material for O2:Ar = 50:50% ratio
compared with O2:Ar = 20:80% ratio, and the actual trend is maintained under the condition
when the heating rate increased. The reducing of oxygen concentration strongly influenced
on the amount of final residue products, particularly at higher heating rates (beyond 10 oC
min–1). At ...the same time, the kinetic analysis of combustion profiles of PTS reveals different
complex dependencies of both, the apparent activation energy (E) and the pre-exponential
factor (logA) with conversion (α), especially in devolatilization and combustion of volatiles
reaction regions. The large variation in Eα attributed to multiple parallel reactions was addressed
through application of deconvolution technique utilizing the Fraser-Suzuki function
as well as nonlinear mechanistic modeling, which also involves determination of composition
of studied biomass. It was shown that Fraser-Suzuki equation very successfully and accurately
fits the kinetic rate curves of entire combustion process, assuming the best selected
the nth-order reaction model.
