Abstract
Disclosed herein is a method of regenerating a titanium-containing molecular sieve catalyst. Particularly, this invention provides a method of regenerating a titanium-containing molecular sieve catalyst used in epoxidation of olefin through simple treatment using a mixture solvent comprising aqueous hydrogen peroxide and alcohol. According to the method of this invention, when the catalyst having decreased activity is regenerated, the activity of the regenerated catalyst is equal to that of new catalyst and can be maintained stable for a long period of time.
