The utility model relates to a catalyst separation system, in particular to a separation system of a catalyst and a carbonyl synthesis product in carbonyl synthesis, belonging to the technical field of carbonyl synthesis. The separation system adopts a two-stage separation method to separate the oxo catalyst and the oxo product. The first-stage separation is mainly for pre-separation and recovery of olefins, and the second-stage separation is mainly for the final separation of the catalyst and the oxo product, and the catalyst is recycled. , the catalyst circulation amount accounts for 1/3 to 1/4 of the total feed amount. The utility model adopts a two-stage system to separate the catalyst solution in the oxo product, fully separates the catalyst from the oxo product, has a short high temperature residence time, does not have any catalyst loss, and simultaneously recycles olefins and alkanes. |
