Title:
HYDROGENATION AND CATALYTIC CRACKING COMBINED PROCESS FOR RESIDUAL OIL
Document Type and Number:
WIPO Patent Application WO/2008/080303
Kind Code:
A1
Abstract:
A hydrogenation and catalytic cracking combined process for residual oil includes introducing
residual oil, acid solid impurities removed catalytic cracking heavy cycling
oil, optional fractional oil and optional distilled products of acid solid impurities
removed catalytic cracking oil slurry into a hydrogenation equipment for residual
oil, loading the resulted hydrogenated residual oil and optional vacuum gas
oil into a catalytic cracking equipment to obtain different products, recycling
the acid solid impurities removed catalytic cracking heavy cycling oil into
the hydrogenation equipment, distilling and separating the catalytic cracking
oil slurry, and recycling the distilled products thereof after removing acid
solid impurities into the hydrogenation equipment. This process combines hydrogenation
and catalytic cracking more efficiently, improves the quality of the hydrogenated
products of residual oil, prolongs the operating cycle of the equipment for hydrogenating
residual oil, increases the yield of hydrogenated diesel oil and catalytic cracking
light oil and reduces the coke amount during catalytic cracking.
