摘要:The main aim of this paper is to do the comparative analysis of predicted results obtained by using the various probability distribution functions. The predicted n th order distributed activation energy model (DAEM) results are obtained after applying the asymptotic expansion technique on the DAEM. Pyrolysis of loose biomass under the isothermal condition is considered to know the validity of distributed activation energy model (DAEM) for the different type of distribution functions of activation energies f ( E ).
