A process for providing a carbon monoxide-containing stream involves a separation of synthesis gas into a hydrogen-rich gas stream and a carbon monoxide-rich gas stream containing carbon monoxide to an extent of 85% by volume or more. The separation is effected in an arrangement composed of three membrane separation stages. Prior to the performance of the membrane separation, the synthesis gas is pretreated for removal of secondary components present in the synthesis gas.

Process for producing carbon monoxide-containing streams

The invention provides an improvement in terms of control and process technology for a method of continuous removal of a component from a liquid mixture using a membrane unit comprising at least one membrane stage. The improvement is that at least some of the overall permeate stream obtained is recycled to the feed vessel and/or beyond the feed vessel but upstream of the conveying device. The presently disclosed method can especially be used for separation of a homogeneously dissolved catalyst from a liquid reaction mixture.

The present invention relates to a process for producing alcohols by hydrogenation of C4 to C20 aldehydes. The process according to the invention is performed in two consecutive hydrogenation stages, wherein the first hydrogenation stage employs an activated metal catalyst based on a nickel metal foam and the second stage employs a supported catalyst containing a catalytically active component from the group consisting of nickel, copper, chromium and mixtures thereof.

Process for the hydrogenation of aldehydes in at least two hydrogenation stages
