Abstract
A catalyst composition containing alkali metal or alkaline earth metal uranate suitable for the conversion of mixtures of carbon monoxide and hydrogen has the formula EQU Cu.sub.a U M.sub.b A.sub.c O.sub.x where M is one or more metals selected from the group consisting of Th, Pd, Mn, Cr, Fe, Co, Zn, Ce, V, Ru, Rh, Al, Re, Os, Pt, Ir, Ag, Ti, La and Zr, A is an alkaline or alkali earth metal and PA1 a is from 0.01 to 5.0; PA1 b is from 0 to 5.0 with the proviso that when M is Th the value of b is less than 1; PA1 c is a number up to 5.0 selected so that the catalyst composition contains more than 2 percent by weight of Metal A; PA1 x is a number such that the valence requirements of the other elements for oxygen are satisfied. The catalyst composition can be used to prepare an alcohol composition containing at least 30 percent by weight of methanol, the remainder of said composition comprising higher alcohols, the distribution of which on a methanol-free basis is PA1 C.sub.2 -10 to 90 weight percent PA1 C.sub.3 -15 to 60 weight percent PA1 C.sub.4 -0.5 to 35 weight percent PA1 C.sub.5 -0 to 15 weight percent PA1 C.sub.6 -0 to 15 weight percent and wherein the percent of C.sub.3 is …
