Stephen C Leviness, Willard N Mitchell: Catalyst rejuvenation in hydrocarbon synthesis slurry with reduced slurry recontamination. Exxon Research and Engineering Company, Jay Simon, September 22, 1998: US05811363 (32 worldwide citation)

A reversibly deactivated, particulate catalyst in a hydrocarbon synthesis slurry is rejuvenated by circulating the slurry from a slurry body through a rejuvenation zone in which hydrogen contacts the slurry and rejuvenates the catalyst to form a rejuvenated catalyst slurry and an offgas which contai ...

Charles W DeGeorge, Robert D Denton: Gas conversion using synthesis gas produced hydrogen for catalyst rejuvenation and hydrocarbon conversion. Exxon Research and Engineering Co, Jay Simon, Jonathan N Provoost, March 28, 2000: US06043288 (31 worldwide citation)

A gas conversion process in which both hydrocarbons and hydrogen are produced from a synthesis gas feed which comprises a mixture of H.sub.2 and CO, uses hydrogen from a portion of the feed for one or more of (i) hydrocarbon synthesis catalyst rejuvenation and (ii) hydroconversion upgrading of at le ...

Stanislaw Plecha, Charles H Mauldin, Larry E Pedrick: Titania catalysts their preparation and use in fischer-tropsch synthesis. Exxon Research and Engineering Co, Jay Simon, September 12, 2000: US06117814 (31 worldwide citation)

Supports for Fischer-Tropsch catalysts with increased strength and attrition resistance are formed by incorporating both silica and alumina into a support comprised primarily of titania; whereupon Fischer-Tropsch active metals can be composited with the support; the catalysts being particularly usef ...

Marty G Bienstock, John G Matragrano, Rutton Dinshaw Patel, Roby Bearden Jr: Thermal process for reducing total acid number of crude oil. Exxon Research and Engineering Co, Jay Simon, July 11, 2000: US06086751 (31 worldwide citation)

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.

Jayoung Koo, Michael J Luton: Method for producing ultra high strength, secondary hardening steels with superior toughness and weldability. Exxon Research and Engineering Company, Jay Simon, August 13, 1996: US05545269 (31 worldwide citation)

High strength steel is produced by a first rolling of a steel composition, reheated above 1100.degree. C., above the austenite recrystallization, a second rolling below the austenite recrystallization temperature, water cooling from above Ar.sub.3 to less than 400.degree. C. and followed by temperin ...
