Patent number: 6024865Abstract: A product of reduced sulfur content is produced from a feedstock which is comprised of a mixture of hydrocarbons and includes sulfur-containing aromatic compounds as unwanted impurities. The process involves separating the feedstock by fractional distillation into a lower boiling fraction which contains the more volatile sulfur-containing aromatic impurities and at least one higher boiling fraction which contains the less volatile sulfur-containing aromatic impurities. Each fraction is then separately subjected to reaction conditions which are effective to convert at least a portion of its content of sulfur-containing aromatic impurities to higher boiling sulfur-containing products by alkylation with an alkylating agent in the presence of an acidic catalyst. The higher boiling sulfur-containing products are removed by fractional distillation.Type: GrantFiled: September 9, 1998Date of Patent: February 15, 2000Assignee: BP Amoco CorporationInventors: Bruce D.

Patent number: 4818373Abstract: A method for updating a concentrate of tar sands bitumen containing fine mineral matter and optionally coarse mineral matter in which solvent-diluted bitumen is contacted for a short time in a riser with hot attrition-resistant substantially catalytically inert acid-resistant fluidizable particles, causing a selective vaporization of the lighter high hydrogen content components of the bitumen. The preferred particles are composed of silica-alumina, most preferably a mixture of mullite and crystalline silica or mullite, crystalline silica and an acid-resistant form of alumina. A portion of the heavier asphaltenes and most of the components which contain metals, sulfur and nitrogen remain on the attrition-resistant fluidizable particles. Fine mineral matter in the bitumen feed also deposits on the fluidized particles instead of being carried over with the vaporized hydrocarbon product.Type: GrantFiled: November 6, 1985Date of Patent: April 4, 1989Assignee: Engelhard CorporationInventors: David B. Bartholic, William J. Reagan

Patent number: 4804459Abstract: A method for upgrading a concentrate of tar sands bitumen containing colloidal clay in which solvent-diluted bitumen is contacted for a short time in a riser with hot attrition-resistant substantially catalytically inert fluidizable microspheres, causing a selective vaporization of the lighter high hydrogen content components of the bitumen. A portion of the heavier asphaltenes and most of the components which contain metals, sulfur and nitrogen remain on the attrition-resistant microspheres. Colloidal clay in the bitumen feed also deposits on the microspheres instead of being carried over with the vaporized hydrocarbon product. The contact material, with deposit, is passed to a burner provided with high velocity air jets which attrites the colloidal clay away from the microspheres and the material removed by attrition is recovered. The heated microspheres are reintroduced into the riser for further contact with incoming diluted bitumen charge.Type: GrantFiled: June 25, 1987Date of Patent: February 14, 1989Assignee: Engelhard CorporationInventors: David B. Bartholic, William J. Reagan

Patent number: 4781818Abstract: Improved noncatalytic nonreactive alumina-silica solid for removing carbonaceous and metallic contaminants including nickel and vanadium from hydrocarbon feedstock by short term, high temperature contact comprises mullite and crystalline silica. In the decarbonizing and demetallizing process, impurities are deposited on the particles of the solid and the major portion of the feedstock is vaporized. After burning carbonaceous deposit from the particles, the hot particles containing nickel and vanadium are recycled into contact with incoming charges of contaminated feedstock. Periodically metals are removed from coke-depleted particles by extraction with a mineral acid at elevated temperature without dissolving or otherwise destroying the alumina-silica particles. The particles are then reintroduced into the system.Type: GrantFiled: January 21, 1988Date of Patent: November 1, 1988Assignee: Engelhard CorporationInventors: William J. Reagan, David W. White, William R. Schultz, L. Alan Jarnagin
