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 e(19.5)-e(59.0)s(-1). Jindongnan lean coal conversions were 8-52% at activation energies of 100-462 kJ/mol. Their corresponding frequency factors were e(13.0)-e(55.8)s(-1). The conversion of corn-stalk skins were 1-84% at activation energies of 62-169 kJ/mol with frequency factors of e(10.8)-e(26.5)s(-1). Datong bituminous coal, Jindongnan lean coal and corn-stalk skins had approximate Gaussian distribution functions with linear ln k(0) to E relationships.
采用热重分析和分布式活化能模型研究了煤和生物质的热分解。积分法得出，大同烟煤在100 - 486 kJ/mol的活化能下转化率为3 - 73%，相应的频率因子为e(19.5)-e(59.0)s(-1)。晋东南贫煤在100 - 462 kJ/mol的活化能下转化率为8 - 52%，其相应的频率因子为e(13.0)-e(55.8)s(-1)。玉米秸秆皮在62 - 169 kJ/mol的活化能下转化率为1 - 84%，频率因子为e(10.8)-e(26.5)s(-1)。大同烟煤、晋东南贫煤和玉米秸秆皮具有近似高斯分布函数，ln k(0)与E呈线性关系。
