  • Conversion of light hydrocarbons to higher hydrocarbons
    Patent number: 5157189
    Abstract: A process is disclosed for catalytically converting light hydrocarbons, such as natural gas, to saturated or unsaturated higher molecular weight hydrocarbons, such as ethylene, propylene, ethyl benzene, and styrene. The process employs gaseous catalyst or a mixture of catalysts selected from hydrogen sulfide, hydrogen halides other then hydrogen fluoride, halogen other than fluorine, sulfur vapor, and/or sulfur containing hydrocarbons.
    Type: Grant

  • Process for the pyrolytic oxidation of methane to higher molecular weight hydrocarbons and synthesis gas
    Patent number: 4973786
    Abstract: A process is disclosed for catalytically converting methane to synthesis gas and one or more saturated or unsaturated higher molecular weight hydrocarbons, such as ethane, ethylene, and acetylene. The process employs a homogeneous gas phase hydrogen halide catalyst other than hydrogen fluoride to faciltiate the pyrolytic oxidation of methane. Alternatively the homogeneous gas phase catalyst may consist of a mixture of gaseous hydrogen halide and gaseous halogen, or a halogen gas.
