摘要: In the gas-phase hydrogenation of free fatty acids and mixtures thereof with acid esters to alcohols on particulate fixed-bed catalysts based metal oxides in presence an at least 50-fold excess recycled hydrogen temperatures 250° 350° C. under pressues from 200 500 bars, acid-sensitive zinc oxide are used corrosive effect starting materials containing catalyst is largely prevented by increasing process temperature within range indicated and/or reducing ratio material hydrogen.
