Abstract
Process for manufacturing a mixture of methanol and higher alcohols by reacting carbon oxides with hydrogen in the presence of a catalyst containing simultaneously copper, cobalt, aluminum and at least one alkali or alkaline-earth metal A selected from lithium, sodium, potassium, rubidium, caesium, beryllium, magnesium, calcium, strontium and barium, in respective atomic ratios of Cu/Co=0.1-5, Al/co=0.7-4, A metals/Co=0.05-3.5, the proportion by weight of each metal to the total metals weight being respectively: copper: 10-65%, cobalt: 5-50%, aluminum: 5-40%, metal A: 0.1-15%, the homogeneity of the catalyst being such that the atomic ratio cobalt/aluminum does not vary by more than 15% with respect to its average value, on a scale of 5 nanometers.
