焙烧温度对Ru/CeO2催化剂在高通量甲醇水蒸气重整制氢反应中催化性能的影响
Effects of calcination temperature on catalytic performance of Ru/CeO2 catalysts for hydrogen production by high flux steam reforming of methanol
摘要
Abstract
The development of high efficiency catalyst is one of the key technologies of hydrogen production by high flux steam reforming of methanol.Using RuCl3 as raw material and CeO2 as support,Ru/CeO2 catalysts were prepared by deposition-precipitation method.The properties of the catalysts were analyzed by XRD,N2 adsorption/desorption,H2-TPR and XPS,and the effect of calcination temperature on the catalytic performance of the catalysts in high flux steam reforming of methanol for hydrogen production was investigated.The results show that with the increase of calcination temperature,the reducing performance of RuOx species increases first and then decreases,and the surface oxygen vacancy relative content increases first and then decreases.Among them,RuOx species in Ru/CeO2-500 catalyst have stronger reducing performance,higher surface oxygen vacancy relative content on the catalyst surface,and better catalytic activity.The methanol conversion rate of Ru/CeO2-500 catalyst is 91.8％under the conditions of reaction temperature of 420 ℃,mole ratio of water and alcohol of 1.2∶1.0 and weight hourly space velocity of methanol and water of 6.0 h-1.关键词
