Abstract
The present invention discloses a process for regenerating titanium-containing catalysts, characterized in that a deactivated catalyst is treated in an acidic solution having a pH value of ≦3, and then dried and calcined. The process is simple in procedure and can make the catalytic activity, selectivity and stability of the regenerated catalyst be recovered to the level of its fresh catalyst.
