PROBLEM TO BE SOLVED: To provide a solid catalyst regeneration method capable of extremely efficiently regenerating a solid catalyst, which is used for forming propylene oxide by the epoxidizing reaction of propylene and organic peroxide in a reactor filled with the solid catalyst, without taking out the catalyst to be regenerated from the reactor. SOLUTION: In the solid catalyst regeneration method for regenerating the solid catalyst used for forming propylene oxide by the epoxidizing reaction of propylene and organic peroxide in the reactor filled with the solid catalyst, a liquid is allowed to flow through the solid catalyst charged in the reactor at a temperature not lower than the highest reaction temperature of epoxidizing reaction. |
