Abstract

Conformément au procédé de l'invention, on conduit l'hydrogénation à l'aide d'un catalyseur sous forme de couche solide et l'on fait passer la substance à hydrogéner sous forme liquide sur le catalyseur. Application à la préparation de la lysine.In accordance with the process of the invention, the hydrogenation is carried out using a catalyst in the form of a solid layer and the substance to be hydrogenated in liquid form is passed over the catalyst. Application to the preparation of lysine.
