Abstract
Process for manufacturing alcohols by reaction of carbon monoxide with hydrogen in the presence of a catalyst containing from 20 to 60% of copper, from 5 to 50% of cobalt, from 5 to 30% of a metal selected from chromium, iron, vanadium and manganese, from 5 to 40% of a rare earth metal, from 0.1 to 5% of an alkali or earth-alkali metal and, optionally, zinc and/or a noble metal from group VIII and/or a binder selected from alumina, magnesia and cements.
Claims26
In a process for manufacturing saturated linear primary alcohols by contacting a gaseous mixture comprising carbon monoxide and hydrogen, and optionally carbon dioxide, with a multimetallic catalyst having a high selectivity for alcohol production, at a temperature of from 150.degree. to 400.degree. C. and a pressure of from 20 to 250 bar;
- the improvement wherein said multimetallic selective catalyst comprises at least five elements, said elements, and the proportion by weight of each element as metal relative to the total weight of said elements as metals, being:
- (a) copper, from 20 to 60%;
- (b) cobalt, from 5 to 50%;
- (c) at least one metal M selected from chromium, iron, vanadium and manganese, from 5 to 30%;
- (d) at least one rare earth metal N, from 5 to 40%;
- and
- (e) at least one alkali or alkaline earth metal A, from 0.1 to 5%;
- whereby the yield of saturated linear primary alcohols having at least two carbon atoms is increased.
