Abstract:
A slurry hydroconversion process is provided in which a carbonaceous chargestock such as a hydrocarbonaceous oil or coal comprising a catalyst containing vanadium or molybdenum or mixtures thereof, is converted to a hydroconverted oil product. A heavy oil portion comprising metal-containing solids is separated from the oil product and partially gasified to produce a carbon-free metal-containing ash which is extracted with oxalic acid. The resulting metal-containing oxalic acid extract is recycled to the hydroconversion zone as catalyst precursor.
Abstract:
A catalyst comprising a composition comprising a catalytic metal component, carbon and hydrogen deposited on a low surface area metal or metal alloy support is provided. Hydrocarbon treating and conversion processes utilizing the catalyst are also provided. The catalyst is particularly suitable for slurry processes.
Abstract:
A combination slurry hydroconversion, coking and coke gasification process is provided wherein solid fines having an average particle size of less than 10 microns in diameter or the ashes thereof recovered from a gaseous product derived from the coke gasification are used as a catalyst in the hydroconversion stage.
Abstract:
A catalytic slurry hydroconversion process for producing normally liquid hydrocarbons from a heavy hydrocarbonaceous oil and from coal is performed in at least two stages in series. The heavy oil is introduced into the first hydroconversion stage and the coal is introduced into any of the hydroconversion stages other than the first stage.
Abstract:
A process for catalytically hydroconverting coal to produce coal liquids is effected by forming a mixture of an oil soluble metal compound, a hydrogen donor solvent and coal, converting the compound to a catalyst within said mixture and reacting the mixture with hydrogen. The recovered hydrogen donor solvent may be recycled to the hydroconversion zone without intervening hydrogenation. Preferred compounds are molybdenum compounds.
Abstract:
Systems and methods are provided for slurry hydroconversion of a heavy oil feed, such as an atmospheric or vacuum resid. The systems and methods allow for slurry hydroconversion using catalysts with enhanced activity and/or catalysts that can be recycled as a side product from a complementary refinery process.
Abstract:
The present invention relates to a process for desulfurizing bitumen and other heavy oils such as low API gravity, high viscosity crudes, tar sands bitumen, or shale oils with alkali metal compounds under conditions to promote in-situ regeneration of the alkali metal compounds. The present invention employs the use of superheated water and hydrogen under conditions to improve the desulfurization and alkali metal hydroxide regeneration kinetics at sub-critical temperatures.
Abstract:
This invention relates to reducing the amount of thiols (mercaptans) in petroleum streams, specifically, mercaptans above the five carbon molecular weight range.
Abstract:
TAN containing oils, e.g., crudes, are treated by flashing to remove substantially all of the water therefrom, thermally treating the recovered liquid to reduce the naphthenic acid content thereof, and re-combining light gases recovered from the flashing step with the treated liquid.
Abstract:
Disclosed is a method which combines catalytic cracking and olefin production using a coked catalytic cracking catalyst as a dehydrogenation catalyst to dehydrogenate an alkane feed stream and form an olefin rich product stream. The method uses a staged backmixed regeneration system to form the dehydrogenation catalyst and to fully reactivate deactivated cracking catalyst for reuse in the cracking reaction. The catalyst preferably comprises a crystalline tetrahedral framework oxide component.
