METHOD FOR REGENERATING SOLID CATALYST

摘要

A process for regenerating a solid catalyst which has been used for producing propylene oxide through an epoxidation reaction of propylene with an organic peroxide in a reactor packed with the solid catalyst , which comprises allowing a liquid to flow through the catalyst packed in the reactor at a temperature not lower than the maximum reaction temperature of the epoxidation reaction. According to the present invention, a catalyst can be regenerated with extremely high efficiency without taking the catalyst to be regenerated out of the reactor.
