Popis: Liquefaction of coal was studied using 3 coals (2 Japanese, 1 Chinese) in the presence of various metal oxide catalysts under conditions of 7-15 MPa of hydrogen and 380-450 C. Tin oxide showed the highest activity on the hydroliquefaction of a Japanese bituminous coal. The conversion of coal reached 100%, and the yield of n-hexane-soluble oil fraction was about 80%. With the 3 coals, it was found that the conversion decreased as the amount of fixed carbon increased. The tin oxide catalyst was reduced to metallic tin, the particles of which were molten and mixed with coal ash. The recovered ash containing tin particles showed almost the same activity as fresh tin oxide catalyst.
