(EN) PHOSPHORUS-CONTAINING HIGH-SILICON MOLECULAR SIEVE, PREPARATION METHOD THEREFOR AND APPLICATION THEREOF
(57) Abstract
(EN)

A phosphorus-containing high-silicon molecular sieve, a preparation method therefor and an application thereof; in terms of oxides and by using the dry basic weight of the molecular sieve as a baseline, the molecular sieve comprises about 86.5-99.8% by weight of silicon, about 0.1-13.5% by weight of aluminum and about 0.01-6% by weight of phosphorus; the XRD spectrum of the molecular sieve has at least three diffraction peaks, the diffraction angle position of a first strong peak being at about 5.9-6.9°, the diffraction angle position of a second strong peak being at about 10.0-11.0°, and the diffraction angle position of a third strong peak being at about 15.6-16.7°. When the phosphorus-containing high-silicon molecular sieve is used to prepare a hydrocracking catalyst, the molecular sieve exhibits improved hydrocracking activity in the presence of a nitrogen-containing substance.
