Abstract
The thermal decomposition of coals and biomass was studied using thermogravimetric analysis with the distributed activation energy model. The integral method resulted in Datong bituminous coal conversions of 3-73% at activation energies of 100-486 kJ/mol. The corresponding frequency factors were e19.5-e59.0 sâ1. Jindongnan lean coal conversions were 8-52% at activation energies of 100-462 kJ/mol. Their corresponding frequency factors were e13.0-e55.8 sâ1. The conversion of corn-stalk skins were 1-84% at activation energies of 62-169 kJ/mol with frequency factors of e10.8-e26.5 sâ1. Datong bituminous coal, Jindongnan lean coal and corn-stalk skins had approximate Gaussian distribution functions with linear ln k0 to E relationships.
