Abstract

A process for the preparation of saturated alcohols by catalytic hydrogenation of acetylenic alcohols at a temperature of from 50.degree. to 200.degree. C. and under a pressure of from 30 to 320 bar, wherein use is made of a catalyst containing from 20 to 85% of nickel oxide, from 0 to 30% w/w of copper oxide, from 1 to 30% w/w of zirconium dioxide, from 1 to 30% w/w of silicon dioxide and from 1 to 30% w/w of aluminum oxide, by weight of the oxidic, unreduced catalyst.
