PROCESS FOR PRODUCING MIXTURES OF METHANOL AND HIGHER ALCOHOLS AND MIXTURES OBTAINED THEREBY. A B S T R A C T Process for the production of mixtures of methanol and higher alcohols to be used, more particularly, alone or in admixture with gasoline, as fuels, compris- ing the steps of reacting H2 and CO, possibly in the presence of CO2, with a molar ratio H2:CO comprised between 0.1 and 20, preferably between 0.5 and 5, at a temperature from 300°C to 500°C, preferably from 350°C to 450°C and under a pressure from 2000 to 16000 KPa, in the presence of a catalyst based on chromium, zinc and at least one alkali metal, wherein the weight ratio of Zn to Cr, considered as oxides, is comprised between 5:1 and 1:1 and the alkali metals or the alkali metals as oxides are in an amount equal to 0.5%-5% by wt relative to the total of the elements considered as oxides.
