Methanol Steam Reforming over Cu-based Catalysts Ⅰ. Effect of Catalyst Composition

在H2O/CH3OH摩尔比为1.3、液空速为1.5h-1、反应温度为220℃条件下,对甲醇水蒸汽重整制氢Cu/Zn/(Fe,Mn,Cr)/AlO催化剂性能进行了考察.研究表明,Cr的加入可以显著提高甲醇的转化率,降低出口气体中的CO含量.与Cu60Zn30Al10催化剂相比,Cu30Zn15Cr45Al10催化剂出口气体中CO的含量降低54%,甲醇的转化率提高约20%.

The performance of the Cu/Zn/（ Fe, Mn, Cr）/AIO catalysts were investigated at 220 ℃ for methanol steam reforming . The mole ratio of steam to methanol was 1.3, and the liquid space velocity was 1.5 h^- 1. The adding of Cr can enhance conversion of methanol and reduce CO production rate . CO content decreased 54% while the methanol conversion increased 20% under 220 ℃ with Cu30Zn15Cr45Al10 catalyst.
