Title:
IMPROVED INTEGRATED PROCESS FOR HYDROGENATION AND CATALYTIC CRACKING OF HYDROCARBON OIL
Document Type and Number:
WIPO Patent Application WO/2009/089681
Kind Code:
A1
Abstract:
An improved integrated process for hydrogenation and catalytic cracking of
hydrocarbon oil includes, under the existence of hydrogen and hydrogenation
condition, residual oil, catalytic cracking recycled oil and optional fractional
oil are contacted with catalyst. The reaction products are separated to obtain
gas, hydrogenated naphtha, hydrogenated diesel oil, and hydrogenated tail
oil. Under the catalytic cracking condition, the hydrogenated tail oil and optional
conventional catalytic cracking feed stock are contacted with catalytic cracking
catalyst. The reaction products are separated to obtain dry gas, liquefied gas,
catalytically cracked gasoline, catalytically cracked diesel oil, and catalytically
cracked recycled oil. It is characterized in that, before contacting hydrogenated
tail oil and/or conventional catalytic cracking feed stock with catalytic cracking
catalyst, the process includes a step of cutting hydrogenated tail oil and/or
conventional catalytic cracking feed stock into at least one light fraction
and one heavy fraction. The process is especially for hydrocarbon oil conversion
for producing more gasoline and diesel oil.
