Publication number: 20170137285Abstract: A reforming catalyst with improved surface area is provided by using high surface area alumina doped with a stabilizer metal as a catalyst support. The surface area of the catalyst can be higher than a typical reforming catalyst, and the surface area can also be maintained under high temperature operation. This can allow use of the catalyst for reforming in a higher temperature environment while maintaining a higher surface area, which can allow for improved dispersion and/or activity of an active metal such as rhodium on the catalyst support. The catalyst can be suitable for production of syngas from natural gas or other hydrocarbon-containing feeds.Type: ApplicationFiled: November 4, 2016Publication date: May 18, 2017Inventors: Matthew S. IDE, John F. BRODY, Jianxin WU, Joshua W. ALLEN, Frank HERSHKOWITZ, Arsam BEHKISH, Arun K. SHARMA, Anastasios I. SKOULIDAS

Patent number: 7772335Abstract: The invention relates to a method for converting an oxygenated hydrocarbon feedstock into an olefin product comprising: (a) forming a CHA framework type aluminosilicate sieve catalyst made from a substantially fluoride-free synthesis mixture comprising silicon and aluminum sources, a slurry medium, and a template, wherein the sieve is substantially free from framework phosphorus and exhibits a Si/Al ratio from about 40-60; (b) optionally formulating the molecular sieve catalyst with an oxidized aluminum-containing precursor matrix material and a clay binder to form a molecular sieve catalyst composition; (c) activating the catalyst by removing/decomposing the template; and (d) contacting the activated catalyst with the feedstock under conditions sufficient to form an olefin product comprising ?about 65% by weight, on a water-free basis, of ethylene and propylene and having an ethylene-to-propylene ratio ?about 1.2. Ethylene- and propylene-containing polymers can be formed from the olefin product.Type: GrantFiled: March 27, 2009Date of Patent: August 10, 2010Assignee: ExxonMobil Chemical Patents Inc.Inventors: Guang Cao, John F.

Patent number: 6927187Abstract: The invention is directed to a method of synthesising silicoaluminophosphate molecular sieves and in particular those of framework type CHA and AEL. The method uses synthesis templates that comprise one or more tertiary dialkylbutylamines, wherein the alkyl groups are not butyl. The use of such templates. especially N,N-dimethylbutylamine, results in SAPO-11 of a desirable platelet morphology.Type: GrantFiled: July 11, 2003Date of Patent: August 9, 2005Assignee: ExxonMobil Chemical Patents Inc.Inventors: Guang Cao, Matu J. Shah, John F. Brody

Patent number: 5476982Abstract: The present invention is directed to a novel catalyst composition and its use in the dehydrogenation of paraffins to olefins. The catalyst comprises an alloy of a Group VIII noble metal and a metal selected from the group consisting of zinc and gallium on a support selected from the group consisting of silica, zinc oxide modified silica and zinc oxide modified silica-pillared clays when said alloy is a zinc alloy, and silica, gallium oxide modified silica and gallium oxide modified silica-pillared clays when said alloy is a gallium alloy. The instant catalyst is an active and selective catalyst for the catalytic dehydrogenation of paraffins to olefins, especially gaseous paraffins, having the added benefit of retaining high activity and selectivity even following repeated regeneration by calcination in oxygen containing gas at temperatures of 450.degree. C. to 650.degree. C., preferably 450.degree. C. to 500.degree. C.Type: GrantFiled: June 14, 1994Date of Patent: December 19, 1995Assignee: Exxon Research & Engineering Co.Inventors: John L. Robbins, Elise Marucchi-Soos, Jack W. Johnson, John F. Brody
