  • Patent number: 5087786
    Abstract: A process for the halogen-assisted conversion of lower alkanes to higher molecular weight hydrocarbons is provided. A first reaction mixture including lower alkanes, a hydrogen halide and an oxygen-containing gas are contacted with a catalytic composition of crystalline copper aluminum borate at appropriate reaction conditions to form an intermediate composition including halogenated alkanes. The halogenated alkanes are subsequently contacted with a catalytic composition of a pentasil molecular sieve material under appropriate reaction conditions to form a product mixture including hydrocarbons having molecular weights greater than the lower alkanes.
    Type: Grant
    Filed: April 25, 1990
    Date of Patent: February 11, 1992
    Assignee: Amoco Corporation

  • Patent number: 5001293
    Abstract: A method for converting halocarbons, especially lower halocarbons like chloromethane, especially methyl chloride, to hydrocarbons, especially higher molecular weight hydrocarbons, wherein a reaction mixture including the halocarbons is contacted with a borosilicate-containing catalytic composition having a specified composition in terms of mole ratios of oxides and a specified X-ray diffraction pattern to form a product mixture of the desired hydrocarbon(s).
