Significant improvements to the activity of skeletal copper catalysts for the water gas shift reaction were achieved by adding small amounts of Cr2O3 to the surface of copper.The presence of Cr2O3 also promoted the activities of skeletalcopper catalysts for both methanol synthesis and methanol steam reforming reactions.Overloading the Cu surface with Cr2O3 reduced the copper surface area,thereby reducing the positive catalytic effect.
Negligible activities were observed for the water gas shift reaction when greater than 1.0 wt.% cobalt additive was deposited on the surface of skeletal Cu.TPR and N2O titration measurements suggest that the Co additive acts as metallic cobalt in skeletal copper catalysts for methanol synthesis and related reactions.This investigation of the role of additives in skeletal Cu catalysts for methanol steam reforming and water gas shift reactions suggests that a formaldehyde intermediate is present in the methanol steam reforming reaction and that hydrolysis of formaldehyde to formic acid dominates over dimerization of formaldehyde to methyl formate in the reaction mechanism.

水气转换反应中骨架铜催化剂的活性的显著提高可通过加入少量氧化铬在铜的表面来实现.在甲醇合成和甲醇蒸汽重整反应中,氧化铬的存在都提升了骨架铜催化剂的活性.铜表面过量的氧化铬减少了铜的表面积,因此降低了实际催化效果.
在水气转换反应中,以大于1.0 %重量比的钴添加剂沉积在骨架铜表面仅有几乎可以忽略的活性.程序升温还原和一氧化氮滴定表明钴添加剂在甲醇合成和有关反应中是骨架铜催化剂中的金属钴起作用.This investigation of这项骨架铜催化剂中添加剂在甲醇蒸汽重整和水气转换反应中的作用的研究暗示着甲醇蒸汽重整反应中存在甲醛中间体,并且反应机理中甲醛到甲酸的水解比甲醛到甲酸甲酯的二聚化反应更占优势.
