In the direct catalytic hydrogenation of triglycerides, triglycerides are reacted continuously with hydrogen at pressures of from 50 to 300 bar and at temperatures of from 160 to 250 DEG C at molar ratios of hydrogen : fatty acid radicals in the triglyceride starting material of from 10 : 1 to 500 : 1 over catalysts which contain from 30 to 40 % by weight of copper, from 23 to 30 % by weight of chromium and from 1 to 7 % by weight of barium - % by weight in each case relative to oxidic catalyst composition - and if desired further transition metals in the form of their oxides and, after the calcination of the components forming the catalyst composition, have been converted with 1 to 10 % by weight - relative to oxidic catalyst - of at least one binder to give lumpy and/or granular moulded articles and activated with hydrogen or a hydrogen-containing gas mixture.
