Abstract

The invention provides a hydrocracking catalyst containing a Ti-P-Y molecular sieve and a preparation method of the hydrocracking catalyst. The preparation method comprises the following steps: mixing and forming amorphous silica and alumina, a Beta molecular sieve and a tungsten-loaded Ti-P-Y molecular sieve prepared by the method, thus obtaining a catalyst carrier, wherein the weight percents of the amorphous silica and alumina, the Beta molecular sieve and the tungsten-loaded Ti-P-Y molecular sieve are respectively 30-70%, 5-15% and 10-30%; loading tungsten and nickel on the catalyst carrier, thus obtaining the hydrocracking catalyst, wherein the weight percents of NiO and WO3 are respectively 1-10% and 10-29%. The hydrocracking catalyst is prepared by the preparation method provided by the invention. The catalyst has relatively high hydrocracking activity and stability, can be used for preparing heavy naphtha with high potential aromatic content and tail oil with low BMCI (Bureau of Mines Correlation Index) and has relatively high chemical material total recovery.

Description

technical field [0001] The invention relates to a hydrocracking catalyst and a preparation method thereof, in particular to a hydrocracking catalyst containing Ti-P-Y molecular sieve and a preparation method thereof, belonging to the technical field of hydrocracking catalysts. Background technique [0002] From the 1990s to the present, hydrocracking technology has developed rapidly, especially the development of a series of continuously upgraded hydrocracking catalysts with high activity, low hydrogen consumption, high selectivity and long-term operation. At present, with the development of the national economy, my country's demand for chemical raw materials such as ethylene and aromatics continues to rise, and the yield of crude naphtha in my country is low, which will lead to insufficient supply of chemical raw materials in my country. Therefore, the design and development of high-quality heavy naphtha Oil catalytic reforming raw materials, and high-quality light naphtha a...
