Patent number: 7795483Abstract: The present invention is a process for producing phenyl-alkanes by paraffin adsorptive separation followed by paraffin dehydrogenation and then by alkylation of a phenyl compound by a lightly branched olefin. The adsorptive separation step employs a silicalite adsorbent and, as the desorbent, a C5-C8 linear paraffin, a C5-C8 cycloparaffin, a branched paraffin such as isooctane, or mixtures thereof. The effluent of the alkylation zone comprises paraffins that are recycled to the adsorptive separation step or to the dehydrogenation step. This invention is also a process that that sulfonates phenyl-alkanes having lightly branched aliphatic alkyl groups that to produce modified alkylbenzene sulfonates. In addition, this invention is the compositions produced by these processes, which can be used as detergents having improved cleaning effectiveness in hard and/or cold water while also having biodegradability comparable to that of linear alkylbenzene sulfonates, as lubricants, and as lubricant additives.Type: GrantFiled: September 9, 2003Date of Patent: September 14, 2010Assignee: UOP LLCInventors: Santi Kulprathipanja, Richard E. Marinangeli, Stephen W. Sohn, Thomas R. Fritsch, R. Joe Lawson

Patent number: 5990369Abstract: The present invention relates to a process for the production of light olefins comprising olefins having from 2 to 4 carbon atoms per molecule from an oxygenate feedstock. The process comprises passing the oxygenate feedstock to an oxygenate conversion zone containing a metal alumninophosphate catalyst to produce a light olefin stream. The light olefin stream is fractionated and a portion of the products are metathesized to enhance the yield of the ethylene, propylene, and/or butylene products. Propylene can be metathesized to produce more ethylene, or a combination of ethylene and butene can be metathesized to produce more propylene. This combination of light olefin production and metathesis, or disproportionation provides flexibility to overcome the equilibrium limitations of the metal aluminophosphate catalyst in the oxygenate conversion zone. In addition, the invention provides the advantage of extended catalyst life and greater catalyst stability in the oxygenate conversion zone.Type: GrantFiled: February 9, 1998Date of Patent: November 23, 1999Assignee: UOP LLCInventors: Paul T. Barger, R. Joe Lawson, Bipin V. Vora

Patent number: 5523508Abstract: Linear alpha-olefin formation via oligomerization of ethylene using transition metal catalysis leads to a Schultz-Flory distribution of oligomers. At modest temperatures formation of heavy oligomers which are waxy solids only partly soluble in the LAO product mix causes reactor plugging and curtailing the time of continuous runs. Recycling a portion of a lighter oligomeric fraction obviates this problem and permits runs uninterrupted by solids formation.Type: GrantFiled: December 29, 1994Date of Patent: June 4, 1996Assignee: UOPInventors: Mark A. Krawczyk, Richard E. Marinangeli, R. Joe Lawson

Patent number: 5510559Abstract: An improved process is disclosed for the conversion of hydrocarbons, using a catalyst comprising a non-zeolitic molecular sieve which has been activity-moderated by controlled carbon deposition. It is of particular interest in skeletal isomerization to increase the proportion of olefins containing tertiary carbons in the product with low formation of undesirable by-products. Controlled carbon deposition increases selectivity to the desired olefin isomers. Product olefins may be further processed to obtain ethers, which enjoy high current interest as components for reformulated gasoline.Type: GrantFiled: May 17, 1994Date of Patent: April 23, 1996Assignee: UOPInventors: Paul T. Barger, Dorothy M. Richmond, Patrick T. Darby, II, R. Joe Lawson

Patent number: 5498810Abstract: A process combination is disclosed to selectively upgrade naphtha to obtain products suitable for further upgrading to reformulated fuels. A naphtha feedstock is hydrogenated to saturate aromatics, followed by selective isoparaffin synthesis to yield light and heavy naphtha and isobutane; isobutane and isopentane in the product are obtained in superequilibrium concentrations. The heavy naphtha may be processed by reforming, light naphtha may be isomerized, and isobutane may be upgraded by dehydrogenation, etherification and/or alkylation to yield gasoline components from the process combination suitable for production of reformulated gasoline.Type: GrantFiled: August 19, 1994Date of Patent: March 12, 1996Assignee: UOPInventors: Paula L.
