A METHOD OF PRODUCING AN ECTRUDED CATALYST CONTAINING COBALT OXIDE AND MOLYBDENUM OXIDE ON AN ALUMINA CARRIER WHICH COMPRISES MIXING ALUMINA, A CARBONCONTAINING MATERIAL SELECTED FROM THE GROUP CONSISTING OF CARBONCEIUS REDUCING AGENTS AND MATERIALS WHICH DECOMPOSE TO CARBONACEOUS REDUCING AGENTS AT CALCINATION TEMPERATURE, A MOLBDENUM COMPOUND CHOSEN FROM THE GROUP CONSISTING OF MOLYBDENUM OXIDE AND A MLYBDENUM COMPOUND WHICH UPON HEATING FORMS MOLBYDENUM OXIDE, AND A COBALT COMPOUND CHOSEN FROM THE GROUP CONSISTING OF COBALT OXIDE AND A COBALT COMPOUND WHICH UPON HEATING FORMS COBALT OXIDE WITH 2.5% TO 10% BY WEIGHT BASED ON THE FINISHED CATALYST OF A STRONG ACID AND SUFFICIENT WATER TO FORM A PASTE OF PROPER CONSISTENCY FOR EXTRUSION, EXTRUDING SAID PASTE THROUGH AN ORIFICE TO FORM, AN EXTRUSION SHAPE, AND CALCINING SAID EXTRUDED SHAPE AT A TEMPERATURE IN THE RANGE OF 400*TO 1,000*F. TO EVAPRATE THE WATER, TO AT LEAST PARTIALLY ACTIVATE THE ALUMINA BY DRIVING OFF WATER OF HYDRATION AND TO STABLIZE THE COBALT BY CONVERTING IT TO ITS OXIDE.
