PROCESS FOR PRODUCING MIXTURES OF METHANOL AND HIGHER ALCOHOLS AND MIXTURES OBTAINED THEREBY. Process for the production of mixtures of methanol and higher alcohols to be used, more particularly, alone or in admixture with gasoline, as fuels, comprising 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.degree.C to 500.degree.C, preferably from 350.degree.C to 450.degree.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. |
