A mixture of solid FCC catalyst particulates and solid sulfur sorbent particulates are circulated through the reactor, regenerator, and reducer to provide for substantially continuous cracking and desulfurization of the hydrocarbon-containing fluid, as well as substantially continuous regeneration of both the FCC catalyst and the sulfur sorbent.Type: ApplicationFiled: July 5, 2002Publication date: January 8, 2004Inventors: Edward L. Sughrue, Gil J. Greenwood

Patent number: 6635168Abstract: The present invention is directed to certain catalyst compositions and processes that are capable of reducing sulfur compounds normally found as part of the gasoline fraction streams of fluid catalytic cracking processes. The present invention requires an equilibrium cracking catalyst composition comprises at least one Y-type zeolite having kinetic conversion activity of at least about 3 in combination with a Lewis acid containing alumina composite present in at least 50 weight percent of the composition. The resultant equilibrium catalyst composition has a kinetic conversion activity of at least about 2.Type: GrantFiled: April 13, 2001Date of Patent: October 21, 2003Assignee: W. R. Grace & Co.-ConnInventors: Xinjin Zhao, Wu-Cheng Cheng, John Allen Rudesill, Richard Franklin Wormsbecher, Pilip Stephen Deitz

Publication number: 20020092795Abstract: Compositions comprising a component containing (i) an acidic oxide support, (ii) an alkali metal and/or alkaline earth metal or mixtures thereof, (iii) a transition metal oxide having oxygen storage capability, and (iv) a transition metal selected from Groups Ib and/or IIb of the Periodic Table provide NOx control performance in FCC processes. The acidic oxide support preferably contains silica alumina. Ceria is the preferred oxygen storage oxide. Cu and Ag are preferred Group I/IIb transition metals. The compositions are especially useful in the cracking of hydrocarbon feedstocks having above average nitrogen content.Type: ApplicationFiled: February 22, 2002Publication date: July 18, 2002Inventors: Alan W. Peters, John A. Rudesill, Gordon Dean Weatherbee, Edward F. Rakiewicz, Mary Jane A. Barbato-Grauso
