摘要

Abstract

The aimof this study is to determine the effect of the main chemical components of biomass: cellulose

hemicellulose and lignin

on chemical kinetics of biomass pyrolysis. The experimentswere designed based on a simplexlattice mixture design. The pyrolysis was observed by using a thermogravimetric analyzer. The curves obtained from the employed analytical method fit the experimental data (R

0.9). This indicated that this method has the potential to determine the kinetic parameters such as the activation energy (E

)

frequency factor (A) and reaction order (n) for each point of the experimental design. The results obtained fromthe simplex-latticemixture design indicated that cellulose had a significant effect on E

and A

and the interaction between cellulose and lignin had an important effect on the reaction order

n. The proposed models were then proved to be useful for predicting pyrolysis behavior in real biomass and so could be used as a simple approximation for predicting the overall trend of chemical reaction kinetics.
