Abstract
A novel catalyst, Ni/Ce-ZrO2, exhibits very high catalytic activity and sta bility even in the stoichiometric steam reforming of methane (H2O/CH4 = 1). Furthermore, when it was employed in oxy-steam reforming, it gave enhanced CH4 conversion (99.1%) at 750 degreesC and the activity was maintained for 100 h. The high catalyst stability is mainly ascribed to the synergistic e ffect of the Ce modifier resulting from high capacity to store oxygen and h igh ability to produce mobile oxygen.
