A process and a plant are specified, with which free fatty acids can be obtained in a simple manner by hydrolysis of fatty acid alkyl esters, especially fatty acid methyl esters (FAME), or alternatively of fatty acid triglycerides present in oils and fats of vegetable and animal origin. According to the invention, a portion of the free fatty acids already produced is recycled back into the reaction mixture, which results in self-acceleration of the hydrolysis reaction.

Process for preparing fatty acids by ester hydrolysis

A plant and a process for carrying out the continuous production of fatty alcohol from fatty acid ester by catalytic trickle-bed hydrogenation, comprising shaft reactors each containing at least one catalyst fixed bed, which are connected with each other via pipe conduits such that they can be traversed by the educt/product mixture one after the other, in freely selectable order.
