The Effect of Pressure on CO2 Reforming of Methane and the Carbon Deposition Route Using Noble Metal Catalysts (book chapter)
Dry reforming of methane and 13C-labeled methane were studied over Pt/ZrO2, Pt/Ce-ZrO2, and 1wt%Rh/Al2O3 at several pressures. It appears that carbon deposited on the catalysts resulted from both methane and CO2. The presence of approximately equal ratios of 13C- and 12C-containing products suggests that the oxygen exchange reaction between CO adn CO2 is very fast. Temperature-programmed oxidation of carbon formed on the catalysts indicates that Co disproportionation contributes significantly to carbon deposition at lower and higher pressures. The Rh/alumina supported catalyst is the most resistant toward carbon desposition both at lower and higher pressures. In all catalysts, methane and CO2 conversion as well as H2/CO ratios decreased wtih increasing pressure.
