Patent number: 7393805Abstract: 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: April 11, 2007Date of Patent: July 1, 2008Assignee: UOP LLCInventors: Edwin P. Boldingh, Antoine Negiz, Gregory F. Maher, Paula L. Bogdan, Dean E. Rende

Patent number: 7304011Abstract: Compositions for reduction of NOx generated during a catalytic cracking process, preferably, a fluid catalytic cracking process, are disclosed. 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.
