摘要： A process for the catalytic hydrogenation of butterfat where non-deacidified butterfat is continuously reacted with hydrogen under pressures of from 20 to 300 bar and at temperatures of from 180.degree. to 250.degree. C. with molar ratios of hydrogen to fatty acid residue in the butterfat 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. The percentages by weight in each case are based on the total oxidic mass of the catalyst. Other transition metals, especially zirconium and cerium, are additionally incorporated into the catalyst. The metals in the catalyst are converted to their oxides by calcination. The catalyst is converted into shaped particulate or granulated elements with from 1 to 10% by weight 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.The reaction products include alcohols, oxo- and hydroxyfatty alcohols corresponding to the natural fatty acid composition of the butterfat and the desired, valuable product, propylene glycol. This process is advantageous since it eliminates the need for preseparation of the relatively short-chain fatty acids (or deacidification) of the butterfat prior to hydrogenation.

摘要： The invention relates to a process for the hydrogenation of native fats, oils and fat derivatives, such as fatty acids and fatty acid esters, to fatty alcohols in a fixed-bed reactor, more particularly in co-current, hydrogen being recirculated in a stoichiometric excess, more particularly in an excess of 10 to 100 fold, and the fat, oil or fat derivative passing through the reactor only once. To minimize the specific hydrogen demand without having to accept significant losses in regard to specific reactor load, product selectivity and catalyst life, the hydrogen is passed successively through at least two fixed-bed reactors 4,10 without the gas issuing from the reactors 4 and entering the following reactors 10 being cooled and the fat, oil or fat derivative is simultaneously introduced into the reactors 4,10.
