This paper studies the influence of promoting admixtures of the Cs formiate on the catalyst activity, selectivity, stability, crystal structure and morphology of Cu-Zn-Al catalyst of low-temperature CO conversion. We test two methods of introducing the promoter, notably into the calcinated as well as into the carbonate catalyst mass. On the experimental side, we determine that Cs introduction in the amount of 1 % allows reducing the catalyst activity in a side reaction of methanol formation by 2-2,5 times. The Cs introduction into the carbonate mass yields better results than into the calcinated one. Since it results in reducing the formation of byproduct methanol and gives a less negative action on the activity, thermostability, crystallinity, specific total surface and copper surface of the catalyst.
