A method for optimizing a method for selective hydrogenation of unsaturated hydrocarbons containing at least three carbon atoms is provided. Single fixed bed main reaction comprising at least two catalyst beds A1 and A2. The two hydrogenation reactors are connected in series and used in a cycled manner according to a series of steps to ensure continuous operation. Otherwise, using the protective reactor B, a method that can be used to bypass the catalyst bed A1, A2 (s) of the main reactor that has been at least partially deactivated. A method in which the catalyst beds A1, A2 of the bypassed main reactor are regenerated and / or exchanged with new catalysts in a simultaneous process. [Selection] Figure 2 |
