  • Sulfur tolerant catalysts for hydrogen production by carbon dioxide reforming of methane-rich gas
    Patent number: 9339797
    Abstract: The present application describes a catalyst that is suitable for the CO2 reforming of methane-rich gases, such as biogas, that is resistant to poisoning by sulfur. The catalyst comprises from about 5 wt % to about 20 wt % Ni and 0 wt % to about 10 wt % Co supported on a support having a formula selected from: (a) Al2O3; (b) M1aOb—Al2O3; and (c) M1aOb—ZrO2—Al2O3, where M1aOb is either CaO or MgO.

  • CATALYSTS FOR FEEDSTOCK-FLEXIBLE AND PROCESS-FLEXIBLE HYDROGEN PRODUCTION
    Publication number: 20130058861
    Abstract: A series of ternary oxide and quaternary oxide catalysts were prepared and evaluated for various reforming processes. Representative examples of these catalysts were found to be active and stable for all the processes tested verifying the “feedstock and process flexible” nature of these catalysts. Thus, feedstock- and process-flexible reforming catalysts for hydrogen and/or syngas production have been developed.
