Effect of Ni content on activity of Ni/Ce0,8La0,2O1,9 catalyst in autothermal reforming of ethanol

The Ni catalysts (0‒15 wt.%) supported on Ce0,8La0,2O1,9 were synthesized for autothermal reforming of ethanol (ATR of C2H5OH) and characterized by X-ray fluorescence analysis, N2 adsorption/desorption, X-ray diffraction and thermal analysis. The effect of Ni content on activity of Ni/Ce0,8La0,2O1,9 catalyst in ATR of C2H5OH was studied. It was demonstrated that Ni content in the catalyst composition determines the temperature of 100% ethanol conversion, distribution and yield of reaction products. The performance of catalysts in ATR of C2H5OH was correlated with their physicochemical characteristics. The optimal content of active component was selected. The complete ethanol conversion was achieved at 300 С with maximum hydrogen yield of ~60% at 60 °С over Ni/Ce0,8La0,2O1,9 catalysts with 10‒15 wt.% Ni
