Publication number: 20110105820Abstract: Methods and compositions for stabilizing the activity of catalytic compositions during catalytic processes, such as alkylation. A catalytic composition comprising a partially deactivated ionic liquid catalyst may be regenerated by reaction with a metal to form reactivated catalyst and an inorganic catalyst precursor; and the catalytic composition may be amended in-process by addition of an organic catalyst precursor for reaction with the inorganic catalyst precursor to form fresh ionic liquid catalyst. The organic catalyst precursor may be protected from water, e.g., during handling, by hydrophobic material(s).Type: ApplicationFiled: November 3, 2009Publication date: May 5, 2011Inventor: Thomas V.

Patent number: 7875754Abstract: A method of operation for producing high yield of alkylate product using catalytic reactors. The catalytic reactors which cycle between reaction mode and catalyst regeneration mode have their contents exchanged with each other at the beginning of each cycle in order to increase the yield of the desired product. This exchange increases the yield by minimizing the contact of reactant in reaction mode with regenerant utilized in regeneration mode. Thus, reducing/preventing the undesirable alternate reaction between the two, which consumes the reactant making it unavailable for the production of the desired product.Type: GrantFiled: July 27, 2006Date of Patent: January 25, 2011Assignee: Lummus Technology Inc.Inventor: Vincent James D′Amico
