摘要：Lewis-acid Zinc metal salt as catalyst, catalytic performance of thermal extraction was studied on Sima lean coal. The effects of different Zinc catalysts on the extraction rate of Sima lean coal were investigated in the conditions of extraction temperature 380°C, the solvent coal ratio was 6:1, and the residence time was 30min.The results showed that ZnSO4 can improve the thermal extraction rate of high rank coal to 46.1%, and the optimal quantity of catalyst was 5%. Recovered ZnSO4 can be recycled, and had good catalytic performance.
