Laboratory-prepared Rh/Na-Y and Rh/Al2O3 catalysts were examined in CO2 reforming of CH4 at atmospheric pressure (1 atm) and high pressure (27 atm). It was found that the use of higher pressure substantially decreased CO2 and CH4 conversion and increased catalyst deactivation during CO2 reforming of CH4, compared to runs at 1 atm for both Rh/Na-Y and Rh/Al2O3 catalysts. Deactivation was related to carbon formation, and the type of support also affects both the amount and structure of carbon deposits.
