Abstract

The paper focuses to explain the in uence of some relevant parameters of biomass pyrolysis on the numerical solution of isothermal nth order distributed activation energy model (DAEM). The upper limit of \dE", the frequency factors, the reaction order, the shape and location parameters of the Weibull distribution are studied. These parameters have been used for estimating the kinetic parameters of the isothermal Weibull DAEM from thermo analytical data of loose biomass. Moreover, asymptotic approach has been adopted to nd the solution of DAEM.
