Patent number: 6392114Abstract: An alkylating agent alkylates an alkylation substrate in a solid catalyst alkylation process in which an alkylation reactor produces a reaction effluent and a catalyst regeneration zone produces a hydrogen-containing regeneration effluent. The alkylation effluent passes to an alkylate fractionation zone, while the regeneration effluent passes to a hydrogen fractionation zone to remove hydrogen and produce a hydrogen-depleted stream that passes to the alkylate fractionation zone. The process recycles hydrogen, and can recycle halogen-containing species as well, within the process while preventing admixture of hydrogen with the alkylating agent. This invention is particularly applicable to alkylation processes that use an olefinic alkylating agent.Type: GrantFiled: December 30, 1999Date of Patent: May 21, 2002Assignee: UOP LLCInventors: Dale J. Shields, Paul A. Sechrist

Patent number: 6103947Abstract: Although alkenes commonly are used to alkylate alkanes using various solid acid catalysts, the process is severely hampered by short catalyst lifetimes attending substantial alkene oligomerization. This problem can be avoided by using an alkene-alkyl chloride mixture as the alkylating agent. Thus, alkylation of isobutane by a butyl chloride/butene mixture at a molar ratio of 1:3 in the presence of an AlCl.sub.3 -type Friedel-Crafts catalyst at 30.degree. C. maintains at least an 80% conversion of (alkene and alkyl chloride) for almost twice as long as is the case for a 1:19 molar ratio of butyl chloride/butene.Type: GrantFiled: December 22, 1998Date of Patent: August 15, 2000Assignee: UOP LLCInventor: Paul T.

Patent number: 5849977Abstract: A process for the alkylation of alkenes having from 2 to 6 carbon atoms with an alkane having from 4 to 6 carbon atoms to afford an alkylate comprises reacting in the liquid phase the alkene and alkane under alkylation conditions in the presence of a novel catalyst comprising: a) a refractory inorganic oxide, b) the reaction product of a first metal halide and bound surface hydroxyl groups of the refractory inorganic oxide, c) a second metal cation, and d) optionally a zerovalent third metal. The refractory inorganic oxide is selected form the group consisting of alumina, titania, zirconia, chromia, silica, boria, silica-alumina, and combinations thereof and the first metal halide is a fluoride, chloride, or bromide of aluminum or boron. The second metal cation is selected from the group consisting of: monovalent metal cations in an amount from 0.0026 up to about 0.20 gram atoms per 100 grams refractory inorganic oxide for lithium, potassium, cesium, rubidium, silver, and copper, and from 0.012 to about 0.Type: GrantFiled: April 10, 1996Date of Patent: December 15, 1998Assignee: UOPInventors: Joseph A.

Patent number: 5763729Abstract: Although olefins commonly are used to alkylate alkanes using various solid acid catalysts, the process is severely hampered by short catalyst lifetimes attending substantial olefin oligomerization. This problem can be avoided by using an alkyl chloride as the alkylating agent. Thus, alkylation of isobutane by olefin in the presence of a modified, AlCl.sub.3 -type Friedel-Crafts catalyst at 30.degree.C falls to about 77% in four hours, whereas alkylation with sec-butyl chloride at the same conditions fell to 88% over 30 hours.Type: GrantFiled: August 8, 1996Date of Patent: June 9, 1998Assignee: UOPInventor: Paul T.
