  • Catalyst for converting methanol and synthesis gas to ethanol
    Patent number: 4361499
    Abstract: A process for selectively preparing ethanol by contacting methanol, hydrogen and carbon monoxide with a solid catalyst comprising rhodium and iron in the reduced state deposited on a support of alumina impregnated with a promoter amount of a heterocyclic amine at reaction conditions correlated so as to favor the formation of a substantial proportion of ethanol.
    Type: Grant
    Filed: September 11, 1980
    Date of Patent: November 30, 1982
    Assignee: Ethyl Corporation
    Inventors: Duane C. Hargis, Michael Dubeck
  • Catalytic composition for the selective formation of ethanol and methyl acetate from methanol and synthesis gas
    Patent number: 4309314
    Abstract: A process for the selective formation of ethanol and methyl acetate by contacting methanol, hydrogen and carbon monoxide with a catalyst comprising rhodium and iron in the reduced state deposited on a support of alumina containing a minor amount of an alkaline metal at reaction conditions correlated so as to favor the formation of a substantial proportion of ethanol and methyl acetate.
