Evaluation of Co-promoted Ni/Al2O3 Catalyst for CO2 Reforming of Ethanol

The performance of Co-promoted Ni/Al2O3 catalyst prepared by co-impregnation method has been investigated for syngas generation through ethanol dry reforming in a tubular fixed-bed reactor at 973 K and various partial pressures of reactants. Both γ-Al2O3 support and 3%Co-10%Ni/Al2O3 catalyst exhibit...
