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 100–486kJ/mol. The corresponding frequency factors were e 19.5 –e 59.0 s −1 . Jindongnan lean coal conversions were 8–52% at activation...
