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.
