摘要：
Hydroliquefaction of a high volatile bituminous coal (Raniganj) was carried out in a batch autoclave. The activities of Harshaw CoMo 0402 T, Fe//2O//3 and SnCl//2 catalysts were evaluated on the basis of the amounts of organic tetrahydrofuran and benzene insolubles. The 250 degree C** plus product fraction was separated into preasphaltenes, asphaltenes, neutral oil, tar acids and tar bases by Integrated Solvent Recycle Chromatography. The average molecular weight of each fraction was determined by Size Exclusion Chromatography. The neutral oil fraction (250 degree C** plus ) was further separated by Gradient Elution Chromatography. The effects of catalyst on the distribution of the above fractions are discussed.
