PROCESS FOR PRODUCING CARBON MONOXIDE-CONTAINING STREAMS
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 AN OLIGOMERIZATION CATALYST HAVING A HYDROTHERMAL TREATMENT STEP
The present invention relates to a process for producing an oligomerization catalyst that includes a step of hydrothermal treatment. The present invention relates also to an oligomerization catalyst produced by the process and to the use thereof in the oligomerization of C2 to C12 olefins.
A process for producing an oligomerization catalyst includes hydrothermal treatment. An oligomerization catalyst produced by the process is useful for the oligomerization of C2 to C12 olefins.
20 olefins involves withdrawing a biphasic stream (liquid/gaseous) and expanding in two stages. Before, between, or after the two stages, the liquid phase is cooled. Only after expansion and cooling is the homogeneously dissolved rhodium catalyst system separated from the residual stream in a three-stage removal.

Process for regeneration of hydrogenation catalysts
The invention provides a process for regenerating a catalyst used for the hydrogenation of an aromatic species, consisting of several steps. First the system is purged with nitrogen, then air is metered in stepwise, and the addition of nitrogen is subsequently ended until only air is present.
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 invention provides a process for regenerating a catalyst used for the ring hydrogenation of an aromatic species, especially an aromatic ester, wherein a gas stream containing a particular amount of oxygen is used for the regeneration.
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 a portion of the overall permeate stream is recycled to the feed vessel and/or beyond the feed vessel but upstream of the conveying device, and the remainder of the overall permeate stream is removed, with the recycled permeate having a higher concentration of the component to be separated off than the removed permeate. The presently disclosed method can especially be used for separation of a homogeneously dissolved catalyst from a liquid reaction mixture.
