摘要

Process for manufacturing a mixture of saturated primary alcohols by reaction of carbon oxides with the 1996 in the presence of a catalyst formed essentially of the following elements: copper, cobalt, zinc, at least one metal selected from the group formed by the alkali metals and alkaline-earth - metal and optionally the zirconium and or at least one metal m chosen from the group formed by scandium, yttrium and the metals of the rare earths, and or n at least one metal selected from the group formed by the noble metals of group viii, the proportion ponderale of each element being of metallic copper 15 - 55, cobalt, 5 - 25, zinc 15 - 70, metal to 0,01 - 5, zirconium 0 - 55, metal m 0 - 20, metal n 0 - 1, the sum of the percentages by weight of zinc and zirconium with respect to the total weight of the metals because of 15 to 70 and the atomic ratios between these metals being cuco 0,2: 1 to 5: 1, zn (zn, zr) 0,05: 1 to 1: 1) and (zn, zr) co 0,5: 1 to 8: 1). / p & & p & the catalyst can be prepare by complexing or by coprecipitation of the catalytic elements.
