  • Increasing metal-tolerance of FCC catalyst by sulfur oxide removal
    Patent number: 5371055
    Abstract: An FCC catalyst system and a process using the catalyst system are disclosed. The catalyst system comprises a metal trap component, such as bastnaesite or barium titanate, and a sulfur oxide acceptor such as a magnesium spinel in addition to a zeolite. The metal trap and sulfur oxide components are preferably in separate particles. The catalyst formulation results in improved activity believed to result from the sulfur oxide acceptor protecting the metal trap component from the harmful effects of sulfur oxides such as the formation of stable metal oxides.
    Type: Grant
    Filed: February 18, 1994
    Date of Patent: December 6, 1994
    Assignee: W. R. Grace & Co.-Conn.
    Inventors: William E. Cormier, Gerald M. Woltermann, John S. Magee, Fred J. Baars, Lawrence L. Upson
