A PROCESS FOR REGENERATION OF ?GG??? SILICATE CATALYST

摘要

Titanosilicate catalyst is used in the oxidation reactions such as allylchloride epoxidation, phenol hydroxylation, Cyclohexanone ammoximation. During the reaction the catalyst is deactivated which further decrease in the efficiency of the oxidation reactions. The present invention provides a method for an efficient regeneration of catalyst titanosilicate catalyst at low temperature below 100°C using a gaseous mixture containing ozone.without isolating the catalyst from the reactor system.
