Jet loop reactor having nanofiltration

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.

主权项

1. A process, comprising:
performing a homogeneous-catalytic reaction of a liquid with a gas and optionally a further fluid, in a device to obtain a target product, wherein said device comprises: a reactor having a pump-driven external liquid circuit; and a membrane separation stage configured to retain a homogeneous catalyst, wherein the reactor is a jet loop reactor, and the pump and membrane separation stage are configured in the same external liquid circuit, and discharging the target product from the liquid circuit together with a permeate of the membrane separation stag; wherein said process comprises reacting a compound having an olefinic double bond with synthesis gas to form an aldehyde, alcohol, or both, by hydroformylation.
