摘要
制备稀土金属离子助催的铜锌基甲醇水蒸汽重整催化剂并分别比较了铜锌和两种以稀土Ce3+,Zr4+为助催剂的铜锌催化剂上甲醇水蒸汽重整制氢的催化性能:在220℃反应条件下,Cu ZnO,Cu ZnO Ce2O3和Cu ZnO ZrO2的甲醇转化率分别为28.1%、37.3%和51.6%,后两个催化剂的氢选择性高达100%,CO的选择性为0.Cu ZnO ZrO2催化剂经60h的运转后,催化剂的性能不变,触氧实验表明该催化剂能满足甲醇燃料电池电动车启动温度低、CO2选择性高的要求.
Catalysts for steamreforming of methanol are prepared and selected. Research results show that the conversion of methanol is respectively 28.1%, 37.3% and 51.6% on the catalyst CZ, CZⅠand CZⅡ, and the selectivity of hydrogen is both as high as 100% on the catalyst CZⅠand CZⅡ at a lower temperature of 220 ℃, and at the same time the selectivity of CO is zero. CZⅡcatalyst show good stability and adaptability for the application on Fuel Cell Vehicles.
