Claims
- 1. A process for the catalytic conversion of carbon monoxide with steam to form hydrogen and carbon dioxide in the presence of a catalyst which comprises the step of passing a reaction mixture comprising carbon monoxide and steam at a temperature of from 300.degree. to 1000.degree. F., but above the dew point temperature of said reaction mixture and at a pressure below the dew point pressure of said reaction mixture but within the range of from 1 to 200 atmospheres over a catalyst comprising a compound of molybdenum supported on a stabilized aluminous support comprising aluminum oxide in the gamma phase in intimate association with a rare earth metal oxide of the lanthanum series.
- 2. The process of claim 1, the further improvement wherein said catalyst includes a compound of cobalt in addition to a compound of molybdenum oxide.
- 3. A process for the conversion of carbon monoxide to carbon dioxide, as defined in claim 1, in which said compounds of cobalt and molybdenum are derived from heat decomposable salts of said metals and which are impregnated onto said stabilized alumina support and calcined to convert said salts to the oxide.
- 4. A process for the conversion of carbon monoxide to carbon dioxide, as defined in claim 1, in which the compounds of cobalt and molybdenum includes one or more sulfides.
- 5. A process for the conversion of carbon monoxide as defined in claim 1, in which the carbon monoxide and steam mixture contains sulfur compounds.
- 6. A process for the conversion of carbon monoxide as described in claim 1, in which the compound of sulfur is hydrogen sulfide.
- 7. A process for the conversion of carbon monoxide, as defined in claim 1, the further step of converting said oxide of molybdenum to the sulfide, including contacting said catalyst with a carbon monoxide steam reaction mixture containing a sulfur-bearing compound.
- 8. A process of CO conversion as defined in claim 1, in which the catalyst upon loss of some of its activity due to the deposition of carbonaceous materials thereon, is regenerated by the steps of oxidizing said catalyst in situ, thereafter sulfiding said catalyst by contacting same with a gas containing a sulfur compound.
