  • Oxidants for gasifying carbon-containing materials
    Patent number: 4367160
    Abstract: This invention relates to the treatment of carbon-containing materials. In one aspect this invention relates to the treatment of carbon-containing materials, such as coal, coke and hydrocarbons to produce oxides of carbon therefrom. In still another aspect, this invention relates to a process for the production of high purity synthesis gas, a mixture of hydrogen and carbon monoxide, from carbon-containing materials. More specifically, this invention relates to inorganic metal-oxygen containing materials useful as the oxidant, oxygen carrier and supplier, and heat transfer agent for the endothermic oxidative gasification of carbon-containing materials.
    Type: Grant
    Filed: October 7, 1981
    Date of Patent: January 4, 1983
    Assignee: Monsanto Company
    Inventors: Charles W. Rooks, George D. Davis, James C. Hill, Talmage D. McMinn, Jr.
  • Ammonia synthesis gas production
    Patent number: 4261856
    Abstract: Ammonia synthesis gas is prepared by contacting coal with air and steam in a fluidized bed. Heat for the reaction is provided by downward flowing hot char through the fluidized bed. The char is heated externally of the fluidized bed by combustion of fuel and/or a portion of the char. Control of the ratio of steam and air to the coal provides a gasification product of approximately 3 moles carbon monoxide plus hydrogen per mole of nitrogen.
    Type: Grant
    Filed: August 24, 1979
    Date of Patent: April 14, 1981
    Assignee: Monsanto Company
    Inventor: Talmage D. McMinn, Jr.
  • Ammonia synthesis gas production
    Patent number: 4253986
    Abstract: Ammonia synthesis gas is prepared by contacting coal with air and steam in a fluidized bed. Heat for the reaction is provided by downward flowing hot thermal refractory material through the fluidized bed. The refractory material is heated externally of the fluidized bed by combustion of fuel. Control of the ratio of steam and air to the coal provides a gasification product of approximately 3 moles carbon monoxide plus hydrogen per mole of nitrogen.

    Inventors: Ronald H. Kahney, Talmage D. McMinn, Jr.
  • Oxygen carrier composition
    Patent number: 3980580
    Abstract: An oxygen carrier composition based on the metals lead, magnesium and aluminum and a vapor phase process for dehydrocoupling toluene and/or toluene derivatives to form stilbene and/or stilbene derivatives and for demethylating toluene and/or toluene derivatives to form benzene and/or benzene derivatives.
