摘要

The present invention relates to a metal modified Y zeolite, and a preparation method and uses thereof. The zeolite is an oxide and comprises 1-15 wt% of IVB group metal, wherein a ratio of the IVB group metal content on the surface of the zeolite to the IVB group metal content in the zeolite is less than or equal to 0.2; and/or a ratio of distorted tetrahedron-coordination framework aluminum to tetrahedron-coordination framework aluminum is (0.1-0.8) : 1.
