摘要：

Hydrogen production by ethanol steam reforming was studied using Ni catalysts supported over MgAl2O4 doped with Ce or Pr. Ni/MgAl2O4-CeO2 catalyst obtained from nickel nitrate impregnation was selected as the best one (final steady conversion = 95.8 %, carbon formation = 0.4 wt% and activity decay = 6.6 %) under the experimental conditions used in this work. Product distribution and ethanol conversion in ethanol steam reforming over a MAP-Ac; b MAP-Nt; c MAC-Ac and d MAC-Nt catalysts.
