摘要

A support for hydrocracking catalyst of hydrocarbon oil, which comprises a modified zeolite obtained by incorporating titanium into a faujasite-type zeolite, wherein the modified zeolite satisfies conditions (a) to (e) as described, and to a hydrocracking catalyst employing the support and a method for hydrocracking of hydrocarbon oil containing aromatics using the catalyst.

主权项

1. A support for hydrocracking catalyst of hydrocarbon oil, which consists essentially of a modified zeolite obtained by incorporating titanium into an ultra stabilized Y zeolite (USY), wherein the modified zeolite satisfies the followings (a) to (e):
(a) the modified zeolite has a titanium content of 1-17% by mass in terms of metal oxide amount, (b) the modified zeolite contains aluminum and silicon in an Al/Si atomic ratio of 0.14-0.35, (c) the modified zeolite has a lattice constant of 24.36-24.48 Å, (d) the modified zeolite has a degree of crystallinity of 30-95%, and (e) the modified zeolite has a specific surface area of 500-850 m2/g.
