Patent number: 6673734Abstract: A catalyst component, a catalyst, and a process for making the component and catalyst are disclosed herein. Also disclosed herein is a fluid catalytic cracking process for converting petroleum feedstocks to lower boiling products wherein the feedstock is contacted with the catalyst. The catalyst component is a crystalline microporous oxide catalyst to which a compound for promoting dehydrogenation and increasing Lewis acidity is effectively added. This catalyst component can be included in an inorganic oxide matrix material and used as a catalyst. Preferably, the compound for promoting dehydrogenation and increasing Lewis acidity is effectively added to a non-framework portion of the crystalline microporous oxide.Type: GrantFiled: August 31, 2000Date of Patent: January 6, 2004Assignee: ExxonMobil Research and Engineering CompanyInventors: William L. Schuette, Albert E. Schweizer

Patent number: 5318695Abstract: A fluid catalytic cracking process for producing relatively low emissions fuels. The feedstock is exceptionally low in nitrogen and aromatics and relatively high in hydrogen. The catalyst is an amorphous silica-alumina or a zeolitic material having a relatively small unit cell size. The feedstock can be characterized as having less than about 50 wppm nitrogen; greater than about 13 wt. % hydrogen; less than about 7.5 wt. % 2+ring aromatic cores; and not more than about 15 wt. % aromatic cores overall.Type: GrantFiled: November 30, 1992Date of Patent: June 7, 1994Assignee: Exxon Research and Engineering CompanyInventors: Paul E. Eberly, William E. Winter, William L. Schuette, William A. Wachter, Tan-Jen Chen

Patent number: 4243557Abstract: An improved catalyst, and process utilizing said catalyst for catalytically cracking a sulfur-containing hydrocarbon feed, and for the fixation of sulfur by the catalyst and transfer thereof from the catalyst regeneration zone to the reaction zone of a catalytic cracking unit. The catalyst comprises an admixture of composite particles, one present in major concentration for providing principally cracking and combustion promoting functions, and the other present in minor concentration for providing principally sulfur fixation and transfer functions. The particle present in major concentration, on the one hand, is constituted essentially of one or more Group VIII noble metals, preferably platinum, composited with a support comprised of a crystalline alumino silicate component distributed in an active cracking catalyst matrix, suitably one constituted of silica-alumina.Type: GrantFiled: December 26, 1978Date of Patent: January 6, 1981Assignee: Exxon Research & Engineering Co.Inventors: Elroy M.

Patent number: 4176049Abstract: A process which comprises recracking a cracked naphtha feed containing up to about 60 percent, suitably from about 20 to about 40 percent olefins, over a crystalline aluminosilicate zeolite catalyst to further crack the naphtha and saturate at least about 50 percent of the olefins, preferably from about 90 percent to about 100 percent of the olefins, based on the weight of said cracked naphtha feed. In a preferred combination a gas oil is catalytically cracked in a first stage to produce a cat cracked naphtha product of high olefin content, and an intermediate boiling component thereof is recracked as a feed in a second stage over a zeolite catalyst to saturate the olefins, and hydrodenitrogenate and hydrodesulfurize said cat cracked naphtha. The recracked cat cracked naphtha is then hydrotreated at low to mild severities and then catalytically reformed (hydroformed) to produce high octane gasoline.Type: GrantFiled: April 3, 1978Date of Patent: November 27, 1979Assignee: Exxon Research & Engineering Co.Inventors: William E.
