The compositions comprise a fluid catalytic cracking catalyst composition, preferably containing a Y-type zeolite, and a particulate NOx composition containing particles of a zeolite having a pore size ranging from about 3 to about 7.2 Angstoms and a SiO2 to Al2O3 molar ratio of less than about 500. Preferably, the NOx reduction composition contains NOx reduction zeolite particles bound with an inorganic binder. In the alternative, the NOx reduction zeolite particles are incorporated into the cracking catalyst as an integral component of the catalyst. Compositions in accordance with the invention are very effective for the reduction of NOx emissions released from the regenerator of a fluid catalytic cracking unit operating under FCC process conditions without a substantial change in conversion or yield of cracked products, e.g., gasoline and light olefins.Type: GrantFiled: April 15, 2004Date of Patent: December 4, 2007Assignee: W.R. Grace & Co. -Conn.Inventors: George Yaluris, Michael Scott Ziebarth, Xinjin Zhao

Patent number: 7273828Abstract: A process for preparing a transalkylation catalyst, the catalyst itself, and a transalkylation process for using the catalyst are herein disclosed. The catalyst comprises rhenium metal on a solid-acid support such as mordenite, which has been treated with a sulfur-based agent. Such treatment reduces the amount of methane produced by metal hydrogenolysis in a transalkylation process wherein heavy aromatics like A9+ are reacted with toluene to produce xylenes. Reduced methane production relative to total light ends gas production results in lower hydrogen consumption and lower reactor exotherms.Type: GrantFiled: May 27, 2004Date of Patent: September 25, 2007Assignee: UOP LLCInventors: Edwin P. Boldingh, Antoine Negiz

Patent number: 7202189Abstract: A catalyst, a process for using the catalyst whereby the catalyst effectively transalkylates C7, C9, and C10 aromatics to C8 aromatics are disclosed. The catalyst comprises a support such as mordenite plus a metal component. The catalyst provides an enhanced life and activity for carrying out the transalkylation reactions at relatively low temperatures. This is achieved by reducing the maximum particle diameter of cylindrical pellets to 1/32 inch (0.08 cm) or a trilobe to 1/16 inch (0.16 cm).Type: GrantFiled: August 24, 2004Date of Patent: April 10, 2007Assignee: UOP LLCInventors: Antoine Negiz, Edwin P.
