Cumene disproportionation over micro/mesoporous catalysts obtained by recrystallization of mordenite

► Micro/mesoporous catalysts were prepared by recrystallization of MOR zeolite. ► Recrystallized MOR showed improved catalytic performance in cumene disproportionation. ► The enhanced activity is due to higher accessibility of the acid sites. ► The increased lifetime is due to the improved transport and coating with mesoporous phase.
