摘要： 研究了金属壁载PdZn/Al2O3/FeCrAl催化剂在不锈钢平板式微型制氢反应器中对甲醇水蒸气重整制氢的催化性能. 结果表明,在反应温度为350 ℃, 甲醇GHSV=1.6 L/(g·h), 水/醇摩尔比为1.2时,甲醇转化率可达100%, H2选择性达99%以上,出口CO含量低于0.5%, 同时催化剂具有很好的稳定性.

Abstract: Methanol steam reforming for hydrogen production over metal wall-coated PdZn/Al2O3/FeCrAl catalyst was investigated in a stainless steel microreformer. The results showed that the methanol conversion of 100%, selectivity of 99% to H2, outlet CO molar fraction of 0.5%, and high stability were achieved over the PdZn/Al2O3/FeCrAl catalyst under the reaction conditions of 350 ℃, methanol GHSV of 1.600 L/(g·h), and H2O/methanol molar ratio of 1.2.
