Abstract

Disclosed is a hydrocracking catalyst, a preparation method and an application thereof. The catalyst comprises a carrier, silicon dioxide and active ingredients loaded on the carrier, wherein the carrier comprises Y molecular sieves and SAPO-34 molecular sieves. The preparation method of the hydrocracking catalyst comprises the following steps: (1) mixing materials comprising Y molecular sieves and SAPO-34 molecular sieves, and then subjecting the mixture to molding, drying and calcinating to obtain a carrier; (2) introducing silane and the active ingredients into the carrier prepared in the step (1), subsequently performing the drying and calcinating to prepare the hydrocracking catalyst. The catalyst prepared with the method can be used for hydrocracking reaction, thereby significantly increase yield of jet fuel.
