CATALYTIC COMPOSITION BASED ON METAL MIXTURE, PREPARATION THEREOF, AND USE Russian patent published in 2004 - IPC

FIELD: hydrogenation-dehydrogenation catalysts. SUBSTANCE: catalytic composition comprising voluminous catalytic particles including at least one non-precious group VIII metal and at least two group VIB metals is prepared by combining above components, which react with each other in presence of protonic liquid, at least one metallic component preserves at least partially in solid state throughout whole preparation procedure. Metals of VII and VIB groups constitute about 50 to about 100% (as oxides) on the total weight of above-indicated voluminous catalytic particles and solubility of these metal components, which are at least partially solid during reaction, is less than 0.05 mole per 100 ml water at 18^o. EFFECT: increased catalytic activity in hydrogenation processes. 19 cl, 1 dwg, 2 tbl, 7 ex
