Rhodium added 6 wt% Mo/HZSM-5 catalyst (Rh/Mo = 0.2) exhibited highly stable and active performances in the methane dehydroaromatization reaction at 1023 K under 0.3 MPa with 2700 mL g(-1) h(-1) of the methane feed with 6% hydrogen addition due to the effective suppression of the coke deposition on the Bronsted acid sites of HZSM-5.
