The invention relates to a catalyst separation method, in particular to a method and a system for separating a catalyst from an oxo product in oxo synthesis, and belongs to the technical field of oxo synthesis. A method for separating an oxo reaction catalyst and an oxo product. The oxo catalyst and the oxo product are separated by a two-stage separation method. The final separation of the oxo product, and the recycle of the catalyst, the recycle amount of the catalyst accounts for 1/3 to 1/4 of the total feed amount. The invention adopts a two-stage system to separate the catalyst solution in the oxo product, fully separates the catalyst from the oxo product, has short high temperature residence time, does not have any catalyst loss, and simultaneously recycles olefins and alkanes. |
