OXIDATIVE DIMERIZATION OF METHANE ON A SUPPORTED PD-AG CATALYST USING A DIFFUSION CONTROLLED CERAMIC WALL REACTOR

Supported palladium-silver oxides were used as catalysts for the partial oxidation of methane by molecular oxygen in a tubular reactor with ceramic wall separation. The ceramic wall controls the O2 supply in the catalyst bed. The results indicate that the reactor configuration can play an important role in methane oxidation. C2H6, C2H4, CO2 and H2O were obtained at temperatures less than 300 °C. At this temperature any contribution from homogeneous gas phase reaction can be ruled out. © 1990 J.C. Baltzer A.G.
