Abstract

In order to find out the appropriate kinetic model for biomass pyrolysis, pyrolysis experiments of four samples (untreated biomass, HCl-washed, 3%KCl-treated and 10% KCl-treated) of sweet sorghum bagasse were performed by Thermogravimetry (TG) separately at different heating rates. The pyrolysis data was processed by the methods of Ozawa、Coats-Redfern integration and Achar-Brindley-Sharp differential, and the kinetic parameters were calculated. The results showed that the activation energy from deduced mechanism functions is more approach to the Ozawa’s than that from tentative mechanism functions, and the deduced mechanism functions can more realistically reflect the dynamic process four samples of sweet sorghum bagasse pyrolysis.
