CATALYTIC HYDROREFINING PROCESS FOR CRUDE OIL

摘要

A catalytic hydrorefining process for untreated crude oil or crude oil freed from naphtha and lighter fractions which comprises subjecting collectively untreated crude oil or crude oil freed from naphtha and lighter fractions to catalytic hydrorefining comprising hydrodemetallization, hydrocracking and hydrodesulfurization, characterized by using as the hydrocracking catalyst a catalyst which comprises a carrier made of a composite consisting of zeolite and ultrafine particles of a titanium-group metal oxide applied on the surfaces of mesopores of the zeolite and at least one member selected from among Group 6, 8, 9 and 10 metals of the periodic table which is supported on the carrier.
