| 摘 要： | 在采用溶胶-凝胶法制备镍基催化剂的基础上研究富氢气氛下CO选择性甲烷化反应行为及工艺条件;考察了反应温度和空速对富氢气氛下CO选择性甲烷化工艺的影响,并通过正交实验确定了相对较适宜的工艺条件。在反应温度为280℃,空速为1800h-1的条件下,CO可以降至0,H2对CO选择性大于96%。完全可以满足质子交换膜燃料电池对氢源的要求。

| Abstract: | The reaction behavior and technological conditions for selective methanation of carbon monoxide in the hydrogen-rich gas over the nickel-based catalyst prepared by sol-gel method were studied.The effects of reaction temperature and space velocity on the process were investigated.The optimum technological conditions were determined by orthogonal tests to be temperature of 280℃ and space velocity of 1800 h-1.Carbon monoxide could be reduced to zero,and the selectivity to hydrogenation of carbon monoxide was over 99% under above conditions,which could completely meet the qualitative requirement of hydrogen for proton exchange membrane fuel cell. |
