Abstract
In the catalytic hydrogenation of fatty acid methyl ester mixtures, the mixtures are continuously reacted with hydrogen under pressures of from 100 to 300 bar and at temperatures of from 160.degree. to 270.degree. C. with molar ratios or hydrogen to fatty acid methyl ester mixture of from 10:1 to 500:1. The reaction is carried out over catalysts which contain from 30 to 40% by weight copper, from 23 to 30% by weight chromium, from 1 to 10% by weight manganese, from 1 to 10% by weight silicon and from 1 to 7% by weight barium (% by weight, based in each case on total weight of the oxidic catalyst) and, if desired, other transition metals in the form of their oxides. After calcination of the components, the catalyst is converted into shaped particulate and/or granulated elements with from 1 to 10% by weight, based on oxidic catalyst, of at least one binder in addition to 1 to 10% by weight graphite. The catalyst is activated with hydrogen or a hydrogen-containing gas mixture. This process enables production of fatty alcohols in high yield from fatty acid methyl ester mixtures containing fatty acid residues in the C.sub.8 to C.sub.22 carbon chain range without prior separation of the mixtures into individual boiling fractions.
