  • NANO PT-CE OXIDE CATALYST FOR ACTIVATION OF METHANE AND A PROCESS FOR THE PREPARATION THEREOF
    Publication number: 20150197421
    Abstract: The present invention provides a process and a catalyst for the production of synthesis gas (a mixture of CO and H2) by partial oxidation of methane. The process provides a direct single step selective vapor phase partial oxidation of methane to synthesis gas over Pt—CeO2 catalyst between temperature range of 350° C. to 800° C. at atmospheric pressure. The process provides a methane conversion of 28-95% with H2 to CO mole ratio of 1.6 to 2.
