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_aO_b-AI₂O₃; and (c) M¹_aO_b—ZrO₂-AI₂O₃, where M¹_aO_b is either CaO or MgO.
