20120035382 | METHOD FOR SEPARATION AND PARTIAL RETURN OF RHODIUM AND CATALYTICALLY EFFECTIVE COMPLEX COMPOUNDS THEREOF FROM PROCESS STREAMS - The invention relates to a method for separating and partially returning transition metals and/or catalytically effective complex compounds thereof from a reaction mixture by combining one at least one-stage membrane separation and an adsorption, wherein a current comprising a catalyst, comprising a transition metal, is divided over at least one one-stage membrane separation step in a transition metal enriched retentate stream that resupplies the reaction mixture and a transition metal depleted permeate stream and the transition metal depleted permeate stream is further supplied to an adsorption step. The invention further relates to a method for producing tridecanals. | 02-09-2012 |
20120046503 | METHOD FOR ENRICHING A HOMOGENEOUS CATALYST FROM A PROCESS FLOW - The invention relates to a method for enriching a homogenous catalyst from a process flow comprising said homogenous catalyst as a component, wherein the process flow is conducted over at least one membrane and wherein the membrane wholly or partially comprises a polymer that has planar polymer units connected to one another via a rigid link and wherein the linker is contorted, such that at least one planar polymer unit is connected to at least one second planar polymer unit via the link, in a non-co-planar arrangement. The invention furthermore relates to a method for producing tridecanal. | 02-23-2012 |

20140343327 | JET LOOP REACTOR HAVING NANOFILTRATION - The invention relates to a device for the continuous, homogeneous-catalysis reaction of a liquid with a gas and optionally an additional fluid, wherein the device comprises at least one reactor having an external liquid circulation driven by a pump, and wherein the device has at least one membrane separation stage that preferably holds back the homogeneous catalyst. The aim of the invention is to specify a device that allows homogeneous-catalysis gas/liquid phase reactions, in particular hydroformylations, which operate with membrane separation of the catalyst to be performed economically at an industrially relevant scale. Said aim is achieved in that a jet loop reactor is provided as the reactor, and that the pump and the membrane separation stage are arranged in the same external liquid circuit. | 11-20-2014 |
20150018576 | METHOD AND DEVICE FOR THE HYDROFORMYLATION OF ISOBUTENE AND FOR THE SEPARATION OF THE PRODUCT MIXTURE - The invention relates to a method for producing a product mixture ( | 01-15-2015 |
