ABSTRACT:
A fluidized-bed catalyst for the production of synthetic natural gas by the methanization of carbon monoxide which catalyst in the unreduced state contains nickel oxide on a carrier material resistant to temperature changes, and a hydraulic cement, said catalyst obtainable by compressing a composition comprising a carrier material and nickel oxide in admixture with hydraulic cement as binder in the wetted condition at a pressure above 1600 kp/cm.sup.2 into a formed body, calcining the so-compressed formed body, curing the so-calcined formed body by treatment with water or steam, recalcining the so-cured formed body and comminuting the same and recovering a comminuted material having a particle size fraction ranging from 40 to 350.mu.. Also disclosed is a process for production of synthetic natural gas by fluidized-bed methanization of carbon monoxide with hydrogen employing such a catalyst.
