Abstract

The invention relates to a hydrocracking catalyst and its preparation and application. The catalyst contains a matrix containing a heatproof inorganic oxide, a Y-type molecular sieve and a carrier of an MFI-structured molecular sieve, wherein the most probable pore of the carrier is 1-30 nm; and pore concentration ratio is 22-48. The most probable pore is measured by a BET method. The pore concentration ratio is the ratio of height of a peak to half-width of the peak in a distribution curve of volume of the pore measured by the BET method changing with the pore. The preparation method of the catalyst comprises preparation of matrix containing the heatproof inorganic oxide, the Y-type molecular sieve and the carrier of the MFI-structured molecular sieve. A preparation method of the carrier comprises mixing of a precursor of the heatproof inorganic oxide, the Y-type molecular sieve, the MFI-structured molecular sieve, a peptizer and water and extrusion molding, wherein temperature of a molded body at the exit of an extruder is 40-150 DEG C. In comparison with the prior art, the hydrocracking catalyst provided by the invention has high catalytic activity and middle distillate selectivity when used in hydrocarbon oil processing and has stronger ability of reducing condensation point of tail oil.

Description

technical field [0001] The invention relates to a hydrocracking catalyst and its preparation and application. Background technique [0002] In recent years, the trend of heavy and inferior crude oil has become increasingly obvious worldwide. At the same time, the demand for middle distillates, reforming and steam cracking raw materials has continued to increase. This promotes the rapid development of heavy distillate processing technology, and catalyst is the most important and key factor. [0003] Catalysts used for the conversion of heavy oil or macromolecules require not only a large pore size and sufficient pore volume, but also a concentrated pore size distribution of the pores in the catalyst (that is, a high pore size concentration). [0004] Since the catalysts used for the conversion of heavy oil or macromolecules are generally obtained by loading catalytically active components on the carrier, the preparation has larger pore size and pore volume, and has a higher ...
