Abstract
The effects of chromium, zinc and cobalt additives on the properties of skeletal copper catalysts for the reactions of methanol synthesis(MS), water gas shift (WGS) and methanol steam reforming (MSR) have been studied. Catalysts were prepared by doping Cr, Zn and Coadditives on the surfaces of fully leached skeletal copper. Small amounts of Cr2O3 were found to significantly enhance the activity for thewater gas shift reaction. Improvements were also observed for methanol steam reforming and methanol synthesis reactions. The presenceof ZnO on the surface of skeletal copper was shown to greatly enhance methanol synthesis, suggesting that very active Cu-ZnO sites werecreated. ZnO also enhanced the activity for both the water gas shift and methanol steam reforming reactions. On the other hand, addition ofCo had no effect on methanol synthesis activity and gave poor selectivity for methanol steam reforming. More significantly, the Co additivereduced the activity of skeletal Cu to the extent that more than 1.1 wt.% Co additive on the surface resulted in negligible activity for theWGS reaction. The reason for the different performance with the Co additive is thought to be the reduction of surface CoO to metallic cobaltunder the reducing conditions of catalyst pretreatment and reaction. Temperature programmed reduction (TPR), titration with N2O, and COchemisorption measurements support this reasoning. This investigation of the role of additives in methanol steam reforming and the water gasshift reactions provides support for a recently proposed pathway for methanol steam reforming reaction over Cu catalysts via a formaldehydeor methyl formate intermediate.
不要怀疑,只要不是机器翻译我就有可能给你了。

大家请注意,某些查不到的词可能是两个单词中间缺少空格而引起的。

楼主不会是把整篇论文都翻译了吧。

摘要
该文研究了在甲醇合成(MS),水煤气转移(WGS),和甲醇蒸汽重组(MSR)中,铬,锌和钴添加剂对于结构铜催化的影响。通过将铬,锌和钴添加剂掺杂于完全过滤的铜表面完成催化。实验发现,少量的三氧化二铬可以增强水煤气转换反应的活动性。在甲醇合成和甲醇蒸汽重组地试验中获得了同样的结论。在结构铜表面中的氧化锌的存在可以增强甲醇的合成,可以生成非常活跃的 Cu-ZnO单元。氧化锌也可以增强水煤气转移和甲醇蒸汽重组反应中的活动性。另一方面,钴添加剂不能影响甲醇合成的活动性,同时会降低甲醇蒸汽重组的选择性。更重要的是,钴添加剂在一定程度上降低了结构铜的活动性,表面上超过1.1 wt.%的钴添加剂对WGS反应中的活动性的影响是可以忽略的。上述试验中,钴添加剂有不同的性能表现,推测是由于在降低催化的预处理和反应时导致的氧化钴表面减少所引起的。温度可控下降(TPR),氧化氮滴定和化学吸收作用测量支持了上述推断。在甲醇蒸汽重组和水煤气转移中添加剂的作用的发现为进来新提出的在钴催化剂上利用甲醛甲脂甲酸作为媒介进行做甲醇蒸汽重组的设想提供了支持。
