The effects of a variety of preparation parameters on the catalytic activity and selectivity for synthesis gas conversion to higher alcohols of potassium promoted copper-cobalt-chromium oxides catalysts have been investigated. Specifically, the effects of 1) the metal salts used as precursors, 2) the amount of citric acid used as a "complexant", 3) the amount of potassium promoter, and 4) catalyst calcination temperature have been studied. Alcohol selectivities as great as 70 wt % with a production yield of 0.12 g/g cat/hr were obtained. alcohols accounted for 50 to 60 wt % of the alcohols produced. It was found that special attention must be paid to calcination temperature and, to a lesser extent, the other parameters mentioned.

Investigation of the catalytic behavior and chemical nature of alkali promoted copper and copper-cobalt-chromium oxide catalysts for the conversion of synthesis gas to methanol and higher alcohols
