Abstract:
     The present invention discloses a preparation method of hydrotreatment catalyst, in particular it is a preparation method of catalyst for residual hydrodenitrification and hydrogenation to remove carbon residue. Said invention is characterized by adding a neutral solution to prewet powdered material in the course of mix-kneading aluminium hydroxide monohydrate and metallic salt material, then adding acid solution and mix-kneading them into plastic body. On the premise of ensuring that said catalyst possesses high strength and stacking density its pore volume, specially its specific surface area are greater than that of catalyst prepared by using one-step solution addition process, and when it is used for treating residuum, its activity is obviously higher than that of existent catalyst.
