| description | The invention relates to process for the regeneration of a catalyst comprising a titanium containing zeolite as catalytically active material comprising a stage comprising introducing a feed stream comprising propene, hydrogen peroxide or a hydrogen peroxide source, and an organic solvent into a reactor containing a catalyst comprising the titanium containing zeolite, subjecting the feed stream in the reactor to epoxidation conditions in the presence of the catalyst, removing a product steam comprising propylene oxide and the organic solvent from the reactor, stopping introducing the feed stream, washing the catalyst with a liquid aqueous system and calcining the washed catalyst. |
