  • Reforming sulfur-containing hydrocarbons using a sulfur resistant catalyst
    Patent number: 7901565
    Abstract: A method of reforming a sulfur containing hydrocarbon involves contacting the sulfur containing hydrocarbon with a sulfur tolerant catalyst containing a sulfur tolerant precious metal and a non-sulfating carrier so that the sulfur tolerant catalyst adsorbs at least a portion of sulfur in the sulfur containing hydrocarbon and a low sulfur reformate is collected, and contacting the sulfur tolerant catalyst with an oxygen containing gas to convert at least a portion of adsorbed sulfur to a sulfur oxide that is desorbed from the sulfur tolerant catalyst.
    Type: Grant
    Filed: July 11, 2006
    Date of Patent: March 8, 2011
    Assignee: BASF Corporation
    Inventors: Thomas Giroux, Earl Waterman, Robert Joseph Farrauto
  • Reforming sulfur-containing hydrocarbons using a sulfur resistant catalyst
    Patent number: 7901566
    Abstract: A method of reforming a sulfur containing hydrocarbon involves contacting the sulfur containing hydrocarbon with a sulfur tolerant catalyst containing a non-sulfating carrier and one or more of a sulfur tolerant precious metal and a non-precious metal compound so that the sulfur tolerant catalyst adsorbs at least a portion of sulfur in the sulfur containing hydrocarbon and a low sulfur reformate is collected, and contacting the sulfur tolerant catalyst with an oxygen containing gas to convert at least a portion of adsorbed sulfur to a sulfur oxide that is desorbed from the sulfur tolerant catalyst.
