PROCESS FOR ACTIVATING A TITANIUM CONTAINING EPOXIDATION CATALYST

Process for activating an at least partly deactivated heterogeneous titanium - containing catalyst for the epoxidation of propene into propylene oxide, which process comprises adding a titanium compound to the liquid feed of an epoxidation reactor before this feed is contacted with the heterogeneous...

Zusammenfassung:	Process for activating an at least partly deactivated heterogeneous titanium - containing catalyst for the epoxidation of propene into propylene oxide, which process comprises adding a titanium compound to the liquid feed of an epoxidation reactor before this feed is contacted with the heterogeneous catalyst inside the reactor, wherein the solubility of the titanium compound in the liquid feed is higher than the amount of titanium compound added to this feed.
