(209e) Study of the Activity of Mo-Oxide Catalysts for the Reforming of Hydrocarbons

Mo-oxide catalysts have been found to display activity and stability for the partial oxidation of liquid hydrocarbons at 1 atm and moderate temperatures. The mechanism of reaction appears to be that proposed by Mars-van Krevelan, which is based on a series of redox cycles taking place on the oxide surface. To improve the catalytic performance, high surface Mo-oxide catalysts were prepared using different methods reported in the literature. In addition, several support materials were tested to determine their effect on the catalytic performance. The hydrocarbons used in this work were isooctane (as model gasoline) and a mixture of dodecane and tetralin (as model jet-A fuel). The results indicate that hydrogen yields above 90% and conversions close to 100% can be reached at temperatures as low as 700°C for model gasoline, and 750°C for model jet-A fuel.
