ABSTRACT:
Esters of unsaturated fatty acids or mixtures thereof can be hydrogenated by a catalysed liquid-phase hydrogenation with hydrogen to give saturated or partially saturated esters of fatty acids or ester mixtures of fatty acids by carrying out the hydrogenation continuously at a pressure of 50 to 350 bar and a reaction temperature of 40 to 150.degree. C. on oxygen-free and support-free shaped bodies which are arranged in a fixed bed and made of pressed powders of elements of the iron subgroup of subgroup VIII of the Periodic Table of the Elements or their alloys with each other or their alloys with elements of subgroup VI; in addition, hydrogenation-inert elements can be present. The shaped bodies have a compressive strength of 20 to 250N on the curved shaped body surface and have an internal surface area of 10 to 90 m.sup.2 /g.
