Distributed Activation Energy Model 分布活化能模型

The distributed activation energy model (DAEM) for biomass pyrolysis assumes that the decomposition of biomass is carried out through a large number of independent reactions, each with its own frequency factor and activation energy. ■ A comprehensive model consisting of three parallel DAEM reactions for lignocellulosic biomass pyrolysis has been developed. ■ A critical study of the Miura-Maki integral method for the estimation of the DAEM parameters has been carried out. ■ A method based on a pattern search algorithm has been presented to estimate the DAEM kinetic parameters. ■ The Logistic distribution has been used to present the activation energy distribution for cellulose pyrolysis.

 

Iterative Linear Integral Isoconversional Method 迭代线性积分等转化率方法

The isoconversional methods's popularity is due to mainly its capability of yielding activation energies as a function of conversion degree without modelistic assumptions. An iterative linear integral isoconversional methods has been developed for the estimation of the kinetic parameters of a complex reaction process. The advantages of the isoconversional method is (1) the method is free of temperature integral approximation; (2) the method is linear; (3) the results obtained from the method are very close to the true values; (4) the conversion rate data is not required.
