Abstract

The invention discloses a preparation method of a hydrocracking catalyst. The method is to first hydrothermally treat the alumina dry rubber powder at low temperature in an ammonia-containing water vapor atmosphere, then impregnate the hydrothermally treated alumina dry rubber powder with a solution containing a hydrogenation active metal component, dry it, and combine it with a molecular sieve Under the action of peptizer or binder, the catalyst is obtained through full rolling, molding, drying and roasting. The method of the invention can improve the pore structure of the catalyst, has a large specific surface area and pore volume, is beneficial to the optimal coordination of the hydrogenation component and the cracking component, has high catalytic activity, and is more suitable for treating high dry point and poor quality Hydrocracking of vacuum distillates is a catalytic process for increasing the production of high-quality heavy naphtha and improving the quality of tail oil products.

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 for heavy distillate oil. Background technique

[0002] Hydrocracking technology has the characteristics of strong adaptability of raw materials, great flexibility of product schemes, high selectivity of target products, good product quality, and high added value. It can directly convert various heavy and low-quality raw materials into clean fuel oil and high-quality chemical raw materials. It has become one of the most important heavy oil deep processing techniques in modern oil refining and petrochemical industries, and has been increasingly widely used at home and abroad. Although the processing capacity of my country's existing hydrocracking units has exceeded 50.0Mt / a, due to the deterioration of domestic crude oil quality year by year, the import of high-sulfur crude oil has increased significantly, and enviro...
