Process for synthesizing a mixture of primary alcohols from a synthesis gas in the presence of a catalyst containing copper, cobalt, zinc and aluminum

Abstract

Process for manufacturing primary alcohols by reacting carbon oxides with hydrogen, in the presence of a catalyst containing, as essential elements, copper, zinc and aluminum, in respective atomic ratios of Zn/Al=0.4:1 to 2:1 Co/Al=0.2:1 to 0.75:1; Cu/Al=0.1:1 to 3:1, the proportion by weight of each metal with respect to the total metals weight being: copper: 10-50%; cobalt: 5-25%; aluminum: 5-30%; zinc: 10-70%, the homogeneity of the catalyst being such that the variations of the atomic ratios Al/Co, Cu/Cc, Zn/Co within the catalyst, at the scale of 5 nanometers are lower than 15% with respect to the average value of said ratio. The catalyst may be prepared by complexing or by coprecipitation of the catalyst elements.
