Document Type and Number:
Japanese Patent JP5345474
Kind Code:
B2
Abstract:
The invention is to provide a support which can give a zeolite-based hydrocracking catalyst having a stable catalyst life and showing high cracking activity over a long period, and to provide a hydrocracking catalyst employing the support and a method for hydrocracking of hydrocarbon oil containing aromatics using the catalyst. The invention relates to 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 the followings (a) to (e), and to a hydrocracking catalyst employing the support and a method for hydrocracking of hydrocarbon oil containing aromatics using the catalyst.
(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, and (c) the modified zeolite has a lattice constant of 24.36-24.48 Å, (d) a degree of crystallinity of 30-95%, and (e) a specific surface area of 500-850 m 2 /g.
