| titleOfInvention | A method for recovering an active component from a catalyst for producing ethylene oxide after use, and a method for producing a catalyst using the recovered component. |
| abstract | The present invention proposes a suitable method for appropriately grasping the catalyst deterioration time, for recovering a deteriorated catalyst component, and for reusing the catalyst. The present invention relates to an ethylene oxide containing silver, rhenium, alumina, silica and cesium, and at least one element selected from the group consisting of tungsten, molybdenum, chromium and vanadium (active auxiliary agent A). A method for recovering rhenium and cesium from a spent catalyst after producing a raw material gas containing ethylene, molecular oxygen and a chlorine compound using a production catalyst and producing ethylene oxide, which is included in the spent catalyst This is a method for recovering rhenium and cesium, characterized by treating a catalyst having a chlorine content (in terms of Cl) of 0.05% by mass or more with water at 20 to 100 ° C. for 0.1 to 10 hours.
