Abstract

The invention discloses a method for preparing a hydrocracking catalyst. The method comprises the following steps of carrying out hydrothermal treatment on alumina dry gel powder, uniformly mixing the treated alumina dry gel powder and at least one acidic cracking material powder, dipping the mixture into a hydrogenation active ingredient-containing metal salt solution, carrying out filtration, drying and crushing, adding a peptizing agent or a binder into the crushed product, and carrying out molding, drying and calcination to obtain the hydrocracking catalyst. The hydrocracking catalyst has high hydrogenation active ingredient content, a large pore volume, a large aperture size and a large specific surface area, and is suitable for hydrocracking of a heavy vacuum distillate having a higher boiling point.

Description

technical field [0001] The invention relates to a method for preparing a hydrocracking catalyst, in particular to a method for preparing a hydrocracking catalyst capable of processing heavy distillate oil with high activity. Background technique [0002] Hydrocracking technology has the characteristics of strong adaptability to raw materials, great flexibility in production operations and product plans, and good product quality. It can directly convert various heavy and low-quality feedstocks into high-quality jet fuel, diesel, and lubricating oil base materials that are urgently needed by the market. As well as chemical naphtha and tail oil steam cracking raw materials for ethylene production, it has become one of the most important heavy oil deep processing processes in modern oil refining and petrochemical industries, and has been increasingly widely used at home and abroad. [0003] However, due to the deterioration of crude oil quality year by year, a substantial increa...
