Title:
METHOD FOR REGENERATING SOLID CATALYST
Document Type and Number:
WIPO Patent Application WO/2002/072255
Kind Code:
A1
Abstract:
A method for regenerating a solid catalyst having been used for producing propylene oxide through an epoxidation reaction of propylene with an organic peroxide in a reactor packed with a solid catalyst, which comprises allowing a liquid to flow through the catalyst packed in the above reactor at a temperature not lower than the maximum temperature of the epoxidation reaction. The method permits the generation of a catalyst with extremely high efficiency, without the need for taking the catalyst to be regenerated out of the reactor.
