A mixt. of methanol and higher alcohols is prepd. by contacting synthesis gas with a S-free catalyst prepd. by (A) impregnating a support with a Ni cpd., a Mo cpd., and opt. a cpd. of Li, Na, K, Rb, Cs and/or Be (I), where the metals are introduced together or separately as soln(s)., and the support is a solid Zn cpd., with specific surface at least 10 square m/g comprising ZnO, a stoichiometric Zn aluminate (ZnAl2O4), A Zn aluminate with a stoichiometric excess of Zn (ZnAl2O4.nZnO, where n = 0.01-10), or a mixed Zn aluminate of formula Zn1-xMxAl2O4 or ZnAl2O4.(n-y)ZnO.MOy, (B) drying, and (C) heat-activating. x = 0.01-0.5; y = 0.01-5; M = Mg, Zr, Ca, Sr, Ba, Co or Cu. USE - The alcohols are used in petrochemistry (prodn. of olefins, ethers, aldehydes, acids) or pure chemistry (prodn. of esters), but the main appln. is in fuels, utilising the good octane properties. |
