Abstract

In the direct catalytic hydrogenation of glyceride oils, the glyceride oils are continuously reacted with hydrogen under pressures of from 20 to 300 bar and at temperatures of from 160.degree. to 250.degree. C. with molar ratios of hydrogen to fatty acid residues in the glyceride oil substrate of from 10:1 to 500:1, the reaction being carried out over catalysts which contain from 30 to 40% by weight copper, from 23 to 30% by weight chromium, from 1 to 7% by weight barium (% by weight, based in each case on oxidic catalyst mass) and, if desired, other transition metals in the form of their oxides and which, after calcination of the components forming the catalyst mass, are converted into shaped particulate and/or granulated elements with from 1 to 10% by weight, based on oxidic catalyst, of at least one binder, and which have been activated with hydrogen or a hydrogen-containing gas mixture.
