Assignee:

Ashland Oil, Inc. - Ashland KY

International Classification:

B01J 2120

US Classification:

165142

Abstract:

An apparatus for upgrading residual portions of crude oils comprising metal contaminants and Conradson Carbon contributing components by the combination of thermal visbreaking with fluid inert solids and catalytic upgrading of naphtha and higher boiling components of thermal visbreaking in separate systems of riser conversion and solids regeneration includes an external solids heat exchange apparatus arrangement utilized to partially cool hot regenerated solids utilized in the solids regeneration systems.

Nov 14, 1979

Appl. No.:

6/094227

Inventors:

George D. Myers - Ashland KY
Lloyd E. Busch - Ashland KY

Assignee:

Ashland Oil, Inc. - Ashland KY

International Classification:

C01G 1118

US Classification:

208113

Abstract:

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.

International Classification:

C10G 1105
C10G 4716

US Classification:

208111

Abstract:

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. A suspension of hydrocarbon vapors and catalyst particles is then passed through the riser discharge for a desired contact time before separation by ballistic separation with a cup about the riser upper to the riser end.

US Classification:

208 73

Abstract:

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. Steam generated by the combination operation effectively reduces the energy requirement of the combustion process.

US Classification:

208120

Abstract:

A process for economically converting carbo-metallic oils to lighter products. The carbo-metallic oils contain 650. degree. F. and material which is characterized by a carbon residue on pyrolysis of at least about 1 and a Nickel Equivalents of heavy metals content of at least about 4 parts per million. This process comprises flowing the carbo-metallic oil together with particulate cracking catalyst through a progressive flow type reactor having an elongated reaction chamber, which is at least in part vertical or inclined, for a predetermined vapor riser residence time in the range of about 0. 5 to about 10 seconds, at a temperature of about 900. degree. to about 1400. degree. F. , and under a pressure of about 10 to about 50 pounds per square inch absolute sufficient for causing a conversion per pass in the range of about 50% to 90% while producing coke in amounts in the range of about 6 to about 14% by weight based on fresh feed, and laying down coke on the catalyst in amounts in the range of about 0. 3 to about 3% by weight. The spent, coke-laden catalyst from the stream of hydrocarbons formed by vaporized feed and resultant cracking products is separated, the sorbed hydrocarbons are stripped from the catalyst particles by contacting them in one or more fluidized beds with hot combustion gases.

Abstract:

A process for the production of high octane gasoline and/or valuable lower molecular weight products from carbometallic oils comprising contacting hydrogen and a carbometallic feed in a progressive flow reaction zone with hot conversion catalysts capable of activating hydrogen. The hydrogen gas may be introduced into the feed prior to or simultaneous with contacting the feed with catalysts. Alternately, the hydrogen gas may be introduced to the catalysts prior to or simultaneously with its contact with the carbometallic feed.
