Abstract
The ATR reactions of iso-octane were initially carried out with Rh-based catalysts (0.5 wt% of Rh) supported onto three kinds of supports, Al2O3, CeO2, and ZrO2. Observed activities were increased in the order of Rh/ Al2O3 > Rh/CeO2 > Rh/ZrO2. Stabilities against carbon coking of these catalysts, however, proved to be increased in the order of Rh/CeO2 > Rh/ZrO2 > Rh/- Al2O3. To derive synergic properties from each of - Al2O3 and CeO2 supports, a CeO2(20 wt%)/-Al2O3 supported Rh catalyst (0.5 wt% Rh) was synthesized and tested for the ATR reactions of iso-octane, showing enhanced activity and stability compared to those with Rh/ -Al2O3. The Rh/-Al2O3 and Rh/-Al2O3/CeO2 catalysts were eventually examined for the ATR reactions of commercial gasoline (GS Caltex, Korea) which contained sulfur, aromatics, and other impurities that could potentially deactivate the catalysts. It turned out that the Rh/-Al2O3 catalyst was significantly deactivated to decrease its activity after 4 h, while the Rh/-Al2O3/CeO2 catalyst proved to be excellent in terms of stability and activity.
