Patent number: 4894141Abstract: A process for upgrading topped crude oils and residual portions comprising material boiling above 552.degree. C. (1025.degree. F.) by the combination of partial demetallizing and decarbonizing of the residual oil before effecting zeolite catalytic cracking thereof is described in conjunction with a product separation process, a combined hydrocarbon gas product concentration section and the use of parallel arranged CO boilers to produce sulfur free flue gas and steam.

Patent number: 4435279Abstract: Novel riser reactor design with associated multiple feed inlet means for contacting regenerated catalyst particles with low quality naphtha, C.sub.5 minus wet gas product of hydrocarbon conversion and a residual oil feed comprising components boiling above about 1025.degree. F. and comprising metal contaminants. Low quality naphtha from thermal cracking is charged either separately or in admixture with C.sub.5 and lower boiling wet gas product of hydrocarbon conversion to the bottom portion of the riser conversion zone for contact with freshly regenerated zeolite cracking catalyst. The vaporous material thus charged conveys the regenerated catalyst at an acceptable velocity to an expanded section of the riser wherein residual oil is charged by a plurality of nozzle means penetrating the wall of the riser in the transition section to the expander user section.Type: GrantFiled: August 19, 1982Date of Patent: March 6, 1984Assignee: Ashland Oil, Inc.Inventors: Lloyd E.

Patent number: 4354923Abstract: A process is disclosed for the production of high octane gasoline and/or other valuable lower molecular weight products from carbo-metallic oils. Examples include crude oil, topped crude, reduced crude, residua, the extract from solvent de-asphalting and other heavy hydrocarbon fractions. These carbo-metallic oils contain quantities of coke precursors and heavy metal catalyst poisons substantially in excess of what is normally considered acceptable for FCC processing (fluid catalytic cracking) and substantial amounts of sulfur, nitrogen and other troublesome components may also be present. Such carbo-metallic oils are converted to the desired products in a catalytic conversion process. Named "RCC" (Reduced Crude Conversion) after a particularly common or useful carbo-metallic feed, the present process is by no means restricted to reduced crude or to oils of petroleum origin, having utility in the processing of oils from coal, shale and other sources.Type: GrantFiled: November 14, 1979Date of Patent: October 19, 1982Assignee: Ashland Oil, Inc.Inventors: George D.
