Title:
PHOSPHORUS-CONTAINING MOLECULAR SIEVE, PREPARATION METHOD THEREFOR, AND APPLICATION THEREOF
Document Type and Number:
WIPO Patent Application WO/2019/085777
Kind Code:
A1
Abstract:
A phosphorus-containing molecular sieve, a preparation method therefor, and an application thereof are provided. The molecular sieve has a phosphorus content of about 0.3-5% by weight of oxide, a pore volume of about 0.2-0.95 mL/g, and a ratio of Brønsted acid to Lewis acid of about 2-10. The molecular sieve has a high ratio of Brønsted acid to Lewis acid, thereby exhibiting higher hydrocracking activity and ring opening selectivity when used to prepare hydrocracking catalysts.
