Abstract
Process for producing mixtures of methanol and higher alcohols comprising feeding, into the reaction zone equipped with a catalytic system, H.sub.2, CO and possibly inert products with a molar ratio H.sub.2 /CO of between 0.2 and 10, at a temperature of between 200.degree. and 460.degree. C., at a pressure of between 2,000 and 30,000 KPa, and at a space velocity of between 1,000 and 40,000 GHSV, wherein the catalytic system corresponds to the following empirical formula: EQU Zn.sub.x Cr.sub.y O.sub.t +z%M.sub.2 O wherein the x/y ratio is greater than 0.5 and less than 1, t is what is necessary for satisfying the valence with which the various elements appear in the catalyst, PA0 M is an alkaline metal selected from potassium and cesium, PA0 z, representing the percentage of alkaline oxide of the final catalyst, when the metal is potassium, is between 0.01 and 8 and, when the metal is cesium, between 0.01 and 20.6.
