摘要 利用原位傅里叶变换红外光谱技术对CuO/ZnO/CeO2/ZrO2催化剂上的甲醇水蒸气重整制氢反应机理进行了研究.结果表明:甲醇水蒸气重整制氢反应主要由甲醇脱氢解离、甲酸甲酯转化和逆水气变换三个过程组成.副产物CO主要是由CO2和H2经逆水气变换反应而生成的,这是造成甲醇水蒸气重整后的CO含量总是低于热力学平衡浓度的原因. The mechanism of methanol steam reforming for hydrogen-making over CuO/ZnO/CeO2/ZrO2 is investigated by in situ FT-IR .The experimental results show that methanol steam reforming for hydrogen-making consists of methanol dehydrogenation ,methyl formate hydrolysis and reverse water gas shift (RWGS) .The by-product CO formation is mainly due to the RWGS reaction ,which is the reason that the CO level in the reforming gas is below the equilibrium concentration .
