1467084 Reforming hydrocarbons SIEMENS AG 29 April 1975 [30 April 1974] 17891/75 Addition to 1402207 Heading C5E [Also in Division B1] Hydrocarbon feeds are converted to a gas mixture containing carbon monoxide and methane and/or hydrogen by passage with a gaseous component comprising free or combined oxygen at cracking temperature over a catalyst comprising a refractory oxidic support and an active component containing the oxides of lanthanum, cobalt, nickel, uranium, cerium and thorium. The catalyst may be in the form of sintered tiles having through bores. The oxygencontaining component may be air, carbon dioxide or steam. The process is particularly suited to cracking the hydrocarbon, i.e. petrol, feed to an internal combustion engine. In such a case, the oxygen-containing component may be a mixture of air and the exhaust gas from the engine. The Examples describe the cracking of a petrol feed at 800‹ C. |
