Catalysts for reduction of CO or CO2 by H2 under pressure at higher temperatures consist of an intimate mixture of alkali or alkaline-earth oxides with other metallic oxides. For example, ZnO is mixed with K chromate or MnO2 with neutral B or tungstate, the mixture pasted with 10% of a 10-20% dextrin solution, granulated, and dried at <320°. Suitable gas mixture contains 50 vol. H2:40 vol. CO. During the reduction, performed at 330°-400°, the CO2 and CH4 formed are removed by refrigeration under high pressure. The liquid product separates into 2 layers which can be further separated. The main fraction (about 60%) consists of PrOH, BuOH, and AmOH, higher alcohols are also formed.
