Pyrolysis Kinetics of Microalgae Residues—A Comparative Study on DAEM Using Different Distribution Functions
摘要
Distributed activation energy model (DAEM) is highly capable of describing closely the pyrolysis of very complicated lignocellulosic materials such as microalgae residues. Various distribution functions can be used for this purpose. In this study, TGA data obtained from pyrolysis of two microalgae residues Chlamydomonas (C. sp. JSC4) and Chlorella sorokiniana (C. sorokiniana CY1) was kinetically and comparatively analysed by fitting to Gaussian, Logistic and Weibull DAEMs. The three models offered reasonable and similar kinetic parameters. In addition, the kinetics analyses with n # 1 resulted in slightly better fit qualities and more reasonable kinetic parameters than n = 1.
