  • Stabilized catalyst carrier and improved carrier configuration for catalytic combustion system
    Patent number: 5509798
    Abstract: A catalyst member for use in processes for the catalytic combustion of gaseous carbonaceous fuels is made from a stabilized carrier having a plurality of gas flow passages extending therethrough defined by channel walls and a catalyst material disposed on the channel walls, wherein the carrier is stabilized against interaction with the catalyst material. The stabilized carrier may be prepared from a monolith comprising silica, magnesia and alumina that has a coating of alumina on the channel walls and by subjecting the coated monolith to stabilizing conditions. The stabilizing conditions may include exposure to high temperature steam.
    Type: Grant
    Filed: October 4, 1994
    Date of Patent: April 23, 1996
    Assignee: Engelhard Corporation
    Inventors: Jennifer S. Feeley, Dianne O. Simone, Leonard M. Quick, Martha M. Hamil
