Abstract
A phosphorus-containing molecular sieve has a phosphorus content of about 0.3-5 wt %, a pore volume of about 0.2-0.95 ml/g, and a ratio of B acid content to L acid content of about 2-10. The molecular sieve has a specific combination of characteristics, including a high ratio of B acid content to L acid content, thereby exhibiting higher hydrocracking activity and ring-opening selectivity when used in the preparation of a hydrocracking catalyst.
