<p>A main hydrogenation catalyst for coal liquefaction hydrogen supplying solvent and a method of preparation thereof, the carrier of the catalyst is alumina, and the active components are metal sulfide of Group VIB or Group VIII. The catalyst which contains the active component in sulfide state is made by co-extruding, kneeding, impregnating, drying, calcining, sulfuring and oil mixing, and it satisfies with the demand of imperfection hydrogenation reaction of the coal liquefaction solution. It can not create the powder during loading, transportation and filling, and the hydrogenation reaction can be directly processed after filling without sulfurization.</p> |
