  • Process for upgrading methane to higher hydrocarbons
    Patent number: 5053576
    Abstract: There is provided a process for the direct partial oxidation of methane with oxygen, whereby organic compounds comprising higher hydrocarbons are produced. The catalyst used in this reaction is a ZnZSM-5 catalyst. This catalyst may be prepared by ion exchanging or impregnating a ZSM-5 catalyst with a suitable zinc salt such as zinc nitrate.
    Type: Grant
    Filed: December 26, 1989
    Date of Patent: October 1, 1991
    Assignee: Mobil Oil Corporation
    Inventors: Scott Han, Robert E. Palermo, Judy A. Pearson, Dennis E. Walsh
  • Process for upgrading methane to higher hydrocarbons
    Patent number: 5023392
    Abstract: There is provided a process for the direct partial oxidation of methane with oxygen, whereby organic compounds comprising higher hydrocarbons are produced. The catalyst used in this reaction is a CuZSM-5 catalyst. This catalyst may be prepared by ion exchanging or impregnating a ZSM-5 catalyst with a suitable copper salt such as copper nitrate.

  • Conversion of methane
    Patent number: 5015798
    Abstract: There is provided a process for the direct partial oxidation of methane with oxygen, whereby organic compounds comprising higher hydrocarbons including C.sub.5 + liquid hydrocarbons are produced. The catalyst used in this reaction may be a ZSM-5 catalyst. The process involves the use of an initial cofeed, such as propane, in admixture with the methane and oxygen to induce the formation of liquid hydrocarbons. As the reaction progresses, the flow of cofeed is shut off, and liquid hydrocarbons continue to be produced.
