摘要： A process for hydroformylating short-chain olefins, especially C2 to C5 olefins can be performed in at least one reactor in which the catalyst system is in heterogenized form on a support. The support is composed of a porous ceramic material, and the process steps a) to c) are conducted when the process is shut down.

摘要： The present invention relates to a simple process for regenerating a hydroformylation catalyst consisting of a heterogenized catalyst system on a support consisting of a porous ceramic material. The invention also relates to a process for the start-up of the hydroformylation reaction after regeneration according to the invention.
