Abstract:
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.

Claim (Index 10):
A process for the continuous production of fatty alcohol from fatty acid ester, in particular wax ester, by catalytic trickle-bed hydrogenation, the process comprising the steps of:\n a) providing fatty acid ester and fresh and recirculated hydrogen; b) producing an educt mixture of fatty acid ester and hydrogen at a pressure in the range from 50 to 250 bar; c) heating of the mixture to a temperature in the range from 150 to 250\u00b0 C.; d) passing of the mixture through a first and then through a second shaft reactor, which each contain at least one catalyst fixed bed designed as trickle bed, wherein the educt mixture is converted into a product mixture which contains fatty alcohol, hydrogen and, depending on the fatty acid ester used, also further alcohols; e) cooling of the product mixture; f) separation of the hydrogen from the liquid product mixture containing fatty alcohol; g) recirculation of the hydrogen for use in step b); and h) discharging the liquid product mixture containing fatty alcohol from the process for the further treatment; wherein the exchange of the catalyst is effected without interruption of operation, in that in step d) traveling of the reaction zone through the catalyst fixed beds of the shaft reactors is observed by determining the respective temperature profile forming along the bed length and varying in time and, when the reaction zone has passed over from the first into the second reactor and when traveling of the reaction zone in the second reactor has progressed to such an extent that an inactive zone has formed above the same in the catalyst fixed bed, its length is sufficient to serve as protection zone for trapping catalyst poisons, the first reactor is put out of operation by introducing the mixture from step c) directly into the second reactor, that the consumed catalyst in the first reactor is replaced by fresh catalyst, and the reactor is again put into operation in that it is connected downstream of the other reactor.
