Hydrocracking catalyst carrier, preparation method thereof and hydrocracking catalyst

Abstract

The invention belongs to the field of petrochemical engineering and fine chemical engineering, and particularly relates to a hydrocracking catalyst carrier, a preparation method thereof and a hydrocracking catalyst. The preparation method comprises the following steps: mixing and kneading boron and silicon-containing pseudo-boehmite, a molecular sieve and a forming aid, forming, drying and roasting to obtain a hydrocracking catalyst carrier; and introducing active metal onto the prepared hydrocracking catalyst carrier, and drying and roasting to obtain the final hydrocracking catalyst. The hydrocracking catalyst prepared by adopting the hydrocracking catalyst carrier has the advantages of high strength and higher macroporous content, is used for flexibly producing high-quality heavy naphtha, aviation kerosene, diesel oil and hydrocracking tail oil, and has excellent activity and target product selectivity performance.
