    摘要: Anode catalysts for conversion of hydrocarbon feeds in solid oxide fuel cell membrane reactors. An anode catalyst may be a mixture of a metal with a metal oxide, for example a mixture of copper or copper-nickel alloy or copper-cobalt alloy with Cr2O3. Mixed oxides can be prepared by dissolving into water soluble salts of the different metals, chelating the metal ions with a chelating agent, neutralizing the solution, removing water by evaporation to form a gel which then is dried, and finally heating the dried gel to form a mixed oxide of the different metals. The chelating agent can be citrate ions, and ammonia can be added to the solution until the pH of the solution is about 8. The mixed oxide so formed then is reduced, for example by hydrogen, to form a composite comprising the metal (Cu, Cu—Co, Cu—Ni) and metal oxide, here Cr2O3. Typically, the composite oxides so formed comprise approximately spherical nanoparticles, and the reduced composites are nanoparticles comprising very small particles of the metal within a network of the oxide, Cr2O3.

    摘要: The presence of complexes predominantly of iron and one or more of chromium, nickel and oxygen and mixtures thereof on the surface of a stainless steel exposed to a feed stream containing hydrocarbons at elevated temperatures tends to give rise to decomposition products of the hydrocarbon. The amount of iron complexes may be reduced in situ without stopping the process by adding to the feed stream 0.001 to 1 vol % a silane and optionally from 0 to 500 ppm based on the weight of the feed stream of sulphur or a sulphur containing compound.
