Catalytic Liquefaction of coal with Highly dispersed Fe_2S_3 Impregnated in-Situ

摘要

Daliuta subbituminous coal, from Shenfu, Shanxi province of China, was liquefied in a 50 mL micro-autoclave apparatus at 440 deg.C, initial hydrogen pressure of 6.0 Mpa, soaking time of 30 min, using a mixture of tetralin and cyclohexane as solvent. The experiments were carried out ]to investigate the effects of in-situ impregnated Fe_2S_3 on the liquefaction conversion, oil and gas yields of the coal, and the aromatic, aliphatic, and polar compouds fraction content in the oil.
