Abstract
Ni–Ce/Al2O3 and Ni–Ce–Fe/Al2O3 catalysts prepared by impregnation were tested in auto-thermal reforming (ATR) of ethanol. With ceria promotion, conversion of ethanol near 100% and selectivity to hydrogen at 103.6% can be achieved at 600 °C in ATR of ethanol, while with both iron and ceria promotion, selectivity to hydrogen at 118.4% is observed, which are higher (57.17% improvement on hydrogen selectivity) than that of the conventional Ni catalyst. In addition, higher stability is also observed during a 31-h test. The improvements are attributed to the restrained acidity and high dispersion of nickel alumina spinel phase.
