STUDY OF DISTRIBUTED ACTIVATION ENERGY MODEL USING VARIOUS PROBABILITY DISTRIBUTION FUNCTIONS FOR THE ISOTHERMAL PYROLYSIS PROBLEM

Glavni cilj rada bio je usporedba rezultata dobivenih uporabom različitih vjerojatnosnih funkcija. Predviđen je model n-toga reda za model raspodjele aktivacijske energije (skr. MRAE), i to primjenom tehnike asimptotske ekspanzije. Piroliza nevezane biomase u izotermalnim uvjetima iskazala se pogodnom za vjerodostojan izračun takva modela. To vrijedi za različite slučajeve raspodjele funkcija aktivacijske energije – f (E).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 nthorder 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)
