富氢气体中一氧化碳选择催化氧化净化初探

Carbon monoxide removal from hydrogen-rich gas by selective catalytic oxidation

对甲醇重整制得的富氢气体中CO催化氧化净化进行了初步的探讨 ,制备了一种催化活性和选择性较好的0 5 %Pt/γ Al2 O3 催化剂 ,在反应温度为 15 0℃、pO2 /pCO=1 5时 ,产物中CO的含量低于气相色谱的最低检测限 ,且氢的消耗量较低。

The CO removal from methanol reformed H 2-rich gas by selective catalytic oxidation was studied. A Pt/γ-Al 2O 3 catalyst with good activity and selectivity was prepared., and at 150℃ reaction temperature,p O2 /p CO =1.5, the content of CO in purified gas is less than GC detected limit and the loss of H 2 is very low.
