SULFUR TOLERANT CATALYSTS FOR HYDROGEN PRODUCTION BY CARBON DIOXIDE REFORMING OF METHANE-RICH GAS

摘要

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) M1 aOb-AI2O3; and (c) M1 aOb-ZrO2-AI2O3, where M1 aOb is either CaO or MgO.
