Patent number: 8492603Abstract: A process for the dimerization of isoolefins, including: contacting an isoolefin with a solid catalyst composition passivated with at least one of an ether, an alcohol, and water; wherein the solid catalyst composition comprises at least one of a solid phosphoric acid catalyst and a resin of a macroporous matrix of polyvinyl aromatic compound crosslinked with a divinyl compound and having thereon from about 3 to 5 milli equivalents of sulfonic acid groups per gram of dry resin; and wherein at least 50% to less than 100% of acid groups in the solid catalyst composition are neutralized with a metal of Al, Fe, Zn, Cu, Ni, or mixtures thereof. The catalyst may be metalized prior to placement in a reactor or may be metalized in situ.Type: GrantFiled: January 12, 2009Date of Patent: July 23, 2013Assignee: Catalytic Distillation TechnologiesInventors: Lawrence A. Smith, William M. Cross

Publication number: 20130184411Abstract: High strength presulfided catalyst for hydrogenating hydrocarbon resins without an in situ sulfiding step. The catalyst particles have a supported metal catalyst structure with presulfided interstitial surfaces with about 20 weight percent of a low molecular weight hydrocarbon resin, based on the weight of the porous supported metal catalyst structure, filling from 90 to 95 percent of the pore volume to improve a crush strength of the catalyst particles. The presulfided catalyst can be stored and/or shipped in an airtight container with an inert atmosphere. The catalyst particles are made by preparing the oxidized catalyst, presulfiding the catalyst, contacting the catalyst with the low molecular weight hydrocarbon resin in an inert atmosphere, sealing the catalyst in a storage/shipping container, loading the reactor with the presulfided, filled catalyst, and contacting the catalyst with an unsaturated hydrocarbon resin under hydrogenation conditions.Type: ApplicationFiled: January 17, 2012Publication date: July 18, 2013Applicant: ExxonMobil Chemical Patents Inc.Inventors: Jose M. Vargas, Thomas R. Barbee, Yuan-Ju Chen
