COPRECIPITATION METHOD FOR PREPARING CATALYTIC COMPOSITION, CATALYTIC COMPOSITION, AND A METHOD FOR HYDROTREATMENT OF HYDROCARBON FEEDSTOCK

摘要

FIELD: petrochemical process catalysts. ^ SUBSTANCE: method comprises association and interaction of at least one dissolved non-precious metal group VIII metal component and at least two dissolved group VIB metal components in reaction mixture to form oxygen-resistant precipitate, which is then sulfidized. ^ EFFECT: simplified preparation procedure, avoided necessity of manipulations under inert atmosphere, and increased catalytic activity of prepared composition. ^ 22 cl, 6 ex
