ABSTRACT:
In a process of recovering and cleaning catalysts in the continuous production of fat alcohols by a catalytic hydrogenation of fatty acids or fatty acid derivatives at temperatures of 240.degree. to 330.degree. C. and pressures of 200 to 700 bar in the presence of copper-chromium oxide catalysts, wherein the reaction is carried out in the presence of material which has been already reacted, the resulting dispersion is circulated through the filter which is due for cleaning until the contents of the stirring vessel is free of solids and the filter cake is substantially free of product, the liquid from which solids have been removed is separated into cleaning liquor and recovered product by a simple sedimentation in a liquid-liquid separator or by a distillation, the recovered product is fed to the main product, the catalyst which is moistened with the cleaning liquor and substantially free of product is withdrawn and, if required, is dryed.
