Study on the Cu-Ni/Y₂O₃-ZrO₂ Catalytic Performance in Ethanol Steam Reforming

Abstract:

Y₂O₃-ZrO₂ support was prepared by two-step precipitation method with ammonia and oxalic acid. A series of Cu-Ni/Y₂O₃-ZrO₂ catalysts were prepared by impregnation method. The catalysts were investigated and then characterized by XRD and SEM results. The activity of catalysts in ethanol steam reforming was studied. The effects of the catalyst composition on the ethanol conversion rate were discussed and the catalysts inactivation phenomenon under the temperature ranging from 673K to 723K was then analyzed. The results show that 1Cu9Ni/1Y9Zr catalyst has higher activity in ethanol steam reforming, over which ethanol conversion rate is higher than 98% under the situation of 623K, while the inactivation of catalysts with Cu/Ni>3/7 at 673K~723K was caused by carbon deposition .
