Patent number: 5833840Abstract: A catalyst composition which comprises a crystalline metallosilicate having the structure of zeolite Beta, phosphorus and a matrix that is substantially free of crystalline aluminum phosphate which has improved resistance to steam deactivation at which has higher cracking activity than analogous catalysts prepared without phosphorus. The crystalline metallosilicate may be used in the as-synthesized form or in the calcined form. Also included is the method to produce the catalyst composition and methods for the use of catalysts prepared by the present method in organic conversion processes. Specific embodiments of the invention involve various techniques for preparation of catalyst containing phosphorus and crystalline metallosilicates having the structure of zeolite Beta. Catalysts prepared according to the method of this invention are useful for organic compound, e.g., hydrocarbon compound, conversion processes.Type: GrantFiled: June 5, 1995Date of Patent: November 10, 1998Assignee: Mobil Oil CorporationInventors: Robert P.

Patent number: 5573657Abstract: A hydrogenation process for reducing the unsaturation of lubricants uses a catalyst which is based on an ultra-large pore crystalline material. The crystalline material has pores of at least 13 .ANG. diameter arranged in a uniform manner and exhibits unusually large sorption capacity demonstrated by its benzene adsorption capacity of greater than about 15 grams benzene/100 grams (50 torr and 25.degree. C.). A preferred form of the catalyst has a hexagonal structure which exhibits a hexagonal electron diffraction pattern that can be indexed with a d.sub.100 value greater than about 18 .ANG.. The hydrogenation catalysts based on these materials are capable of reducing the unsaturation in poly alpha olefin lubricants to a low level.Type: GrantFiled: September 20, 1994Date of Patent: November 12, 1996Assignee: Mobil Oil CorporationInventors: Thomas F. Degnan, Richard C. Dougherty, George H. Hatzikos, Stuart S. Shih, Tsoung Y. Yan

Patent number: 5470810Abstract: This invention relates to the catalyst composition resulting from the addition of phosphorus, and optionally, a matrix material, to a porous crystalline material having the structure of MCM-22, along with the method for making the catalyst composition, and the method for using the catalyst composition in catalytic cracking. It is desirable to improve the hydrothermal stability of the catalysts which are based upon porous crystalline materials having the X-ray structure of MCM-22 to increase the activity that the catalyst maintains after repeated cycles of steaming such as is experienced in the FCC process. It has been found that phosphorus addition to a porous crystalline material having the structure of MCM-22 improves the hydrothermal stability of the resulting catalyst. This improved catalyst is useful in organic conversion processes, e.g., catalytic cracking processes.Type: GrantFiled: February 2, 1994Date of Patent: November 28, 1995Assignee: Mobil Oil CorporationInventors: Thomas F. Degnan, Anthony S. Fung, George H. Hatzikos, Gordon J. Kennedy, Jocelyn A. Kowalski

Patent number: 5393717Abstract: There is provided a process for regenerating a coked catalyst comprising a zeolite and a noble metal such as platinum. The process involves treating the coked catalyst under somewhat mild oxidation conditions, whereby a sufficient portion of the coke is removed from the catalyst to restore the hydrocarbon sorption properties of the zeolite component to the level observed in the non-coked form. Surprisingly, the original activity of the catalyst is substantially restored, even though a substantial amount of coke remains on the regenerated catalyst.Type: GrantFiled: May 18, 1993Date of Patent: February 28, 1995Assignee: Mobil Oil Corp.Inventors: Minas R. Apelian, Anthony S. Fung, George H. Hatzikos, Clinton R. Kennedy, Chung-Hur Lee, Thomas R. Kiliany, Poh K. Ng, David A. Pappal

Patent number: 5256277Abstract: Paraffins, especially paraffins in the C.sub.4 -C.sub.8 range, are isomerized to iso-paraffins over an isomerization catalyst comprising a noble metal such as platinum on a support material comprising an inorganic, non-layered, porous, crystalline phase aluminosilicate material with pores of at least 13 .ANG. and which exhibits, after calcination, an X-ray diffraction pattern with at least one peak at a d-spacing greater than 18 .ANG.. These materials have a high surface area and sorption capacity marked by a benzene adsorption capacity of greater than about 15 grams benzene per 100 grams at 50 torr and 25.degree. C. In its preferred form, the support material has a uniform, hexagonal arrangement of pores with diameters of at least about 13 .ANG. and a hexagonal electron diffraction pattern that can be indexed with a d.sub.100 value greater than about 18 .ANG. which corresponds to at least one peak in the X-ray diffraction pattern.Type: GrantFiled: July 24, 1991Date of Patent: October 26, 1993Assignee: Mobil Oil CorporationInventors: Kenneth J.
