Promotion of Ni/MgAl2O4 Catalysts with rare earths for the ethanol steam reforming reaction

Abstract

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.
