  • NOx reduction compositions for use in FCC processes
    Publication number: 20050205465
    Abstract: 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: Application
    Filed: December 17, 2004
    Publication date: September 22, 2005
    Inventors: Alan Peters, John Rudesill, Gordon Weatherbee, Edward Rakiewicz, Mary Jane Barbato-Grauso

  • NO.sub.x reduction compositions for use in FCC processes
    Patent number: 6143167
    Abstract: 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 NO.sub.x 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/IIIb transition metals. The compositions are especially useful in the cracking of hydrocarbon feedstocks having above average nitrogen content.
