Abstract:
     The preparation method of high-activity hydrotreating catalyst is characterized by adding a neutral solution in the course of mix-kneading aluminium hydroxide monohydrate and metallic salt material, and uniformly stirring them, then mix-kneading them with peptizing acid so as to reduce addition quantity of peptizing acid and prolong mix-kneading time. The catalyst prepared with said method possesses larger specific surface area and more centralized pore distribution as compared with existent catalyst. Said invented catalyst can be used for residual hydrodenitrification and removal of carbon residue.
