Ni-Mo-Nd-ZrOx催化剂在乙醇水蒸气重整制氢反应中的性能
Performances of Ni-Mo-Nd-ZrOxcatalysts in steam reforming of ethanol for hydrogen production
摘要
Abstract
Nd-ZrOx support was synthesized through coprecipitation and then Ni-Mo-Nd-ZrOx catalysts were prepared through impregnation. The activities of the catalysts in ethanol steam reforming were studied in a fi xed bed reactor. The catalysts were characterized by means of XRD and TPR to investigate their crystalline phases and reducibility. The results showed that the major components of the support was solid solution (Zr0.9Nd0.1)O1.95 and there was a small amount of cubic phase Nd2O3;Ni component was highly dispersed on the support surface in the form of cubic NiO and a little of NiNd2O4 spinel formed. Cubic Ni was found on the catalysts after reduction with hydrogen at 600℃. The catalysts showed high catalytic activities in the ethanol steam reforming. Under the conditions of (Ni9.69Mo0.323)/(Nd8Zr32)Ox as the catalyst and reaction temperature 600℃,the conversion of ethanol and the selectivity to H2 were nearly 100% and 69.14% respectively,and carbon deposition,sintering and catalyst deactivation were not found in the reaction process.关键词
