Asymptotic approximations to the distributed activation energy model for non isothermal pyrolysis of loose biomass using the weibull distribution

摘要

This paper explains the influence of some relevant parameters to biomass pyrolysis, described by the asymptotic solution of non-isothermal n~(th) order distributed activation energy model using the Weibull distribution. Investigated parameters are the integral range, the frequency factors, heating rate, the reaction order, and the shape, scale and location parameters of the Weibull distribution. These parameters have been used for evaluation of the kinetic parameters of the non-isothermal Weibull DAEM from thermo-analytical data of biomass pyrolysis.
