    摘要: The invention relates to a method for producing alcohols by homogeneously catalysed hydroformylation of olefins to aldehydes and subsequent hydration of the aldehydes. The invention further relates to a system for carrying out the method. The main focus is on the separation technique for work-up of the hydroformylation mixture. The problem addressed by the invention is that specifying a work-up method for hydroformylation mixtures that utilises the specific advantages of known separation technologies but at the same time largely avoids the specific disadvantages of said separation technologies. The most important objective is to create a catalyst separation system that is as complete and at the same time conservative as possible and that operates in a technically reliable manner and entails low investment and operating costs. The method should be unrestrictedly suitable for processing the reaction output from oxo systems in “world scale” format. The problem is solved by combining membrane separation units and a thermal separation unit, the thermal separation unit being operated in such a manner that 80% to 98% of the mass introduced with the product stream into the thermal separation unit exits the thermal separation unit again as a head product.

    摘要: 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.

    摘要: The invention relates to processes for preparing aldehydes by hydroformylation of alkenes, in which an alkene-containing feed mixture is subjected to a primary hydroformylation with synthesis gas in the presence of a homogeneous catalyst system, the primary hydroformylation being effected in a primary reaction zone from which a cycle gas containing at least some of the products and unconverted reactants of the primary hydroformylation are drawn off continuously and partly condensed, with recycling of uncondensed components of the cycle gas into the primary reaction zone, and with distillative separation of condensed components of the cycle gas in an aldehyde removal stage to give an aldehyde-rich mixture and a low-aldehyde mixture. The problem that it addresses is that of developing the process such that it achieves high conversions and affords aldehyde in good product quality even in the case of a deteriorating raw material position. More particularly, a solution is to be found for making legacy oxo process plants capable of utilizing lower-value raw material sources. This problem is solved by separating the low-aldehyde mixture into a retentate and a permeate by means of a membrane separation unit in such a way that alkenes present in the low-aldehyde mixture become enriched in the permeate, while alkanes present in the low-aldehyde mixture become enriched in the retentate. The alkene-rich permeate is then transferred into a secondary reaction zone and subjected to a secondary hydroformylation therein with synthesis gas in the presence of an SILP catalyst system. The reaction product obtained from the secondary hydroformylation is recycled into the aldehyde removal stage.
