Abstract
Alcohols, particularly linear saturated primary alcohols, are manufactured from CO and H.sub.2 in the presence of a catalyst comprising at least 4 essential elements, copper, cobalt, a third metal selected from chromium, iron, vanadium and manganese, and at least one alkali metal. A preferred method for manufacturing the catalyst is also described; it comprises the use of a complexant, such as citric acid.
Claims12
A process for manufacturing linear saturated primary alcohols, by reacting carbon monoxide with hydrogen at a pressure between 20 and 250 bars and a temperature between 150.degree. and 400.degree. C., in the presence of a catalyst, characterized in that the catalyst contains at least 4 essential elements:
- (a) copper
- (b) cobalt
- (c) at least one element M selected from chromium, iron, vanadium and manganese, and
- (d) at least one alkali metal A, in the following atomic proportions:
- Cu.sub.x Co.sub.y M.sub.z A.sub.v where x is from 0.1 to 1, y from 0.1 to 1, z from 0.2 to 1 and v from 0.001 to 0.25 times the sum (x + y + z).
