Two Chinese coals with different reductive properties and mineral compositions were selected as the experimental samples to determine their pyrolytic characteristics. The minerals in two coals were successively leached with water, HCl and HF solutions to investigate the influence of minerals on the pyrolytic properties of the two coals. The results show that the alkali and alkaline earth metals (AAEM) minerals play an obvious catalytic role on the pyrolysis of different reductive coals, in particular, the secondary devolatilization phase. The pyrolysis process of all coal samples studied can be described by three independent first order kinetic model and the kinetic parameters of these samples during pyrolysis are affected by the minerals removed in different leaching step.
