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.
