Abstract: The catalytic performance of methane aromatization in the absence of oxygen over Mo based catalysts using the fourth period transitional metal ions exchanged HZSM-5 as the supports have been studied in the paper. Moreover, the activity of the catalysts was correlated with the amount of deposited carbon over the catalysts after reaction. By introduction of transitional metal ions to the exchanged sites of H-ZSM-5, the metal ions acted as the promoters and controlled the production of deposited carbon, so enhanced activity and stability of the catalysts to some extent. Among the ions exchanged MoO3/MHZSM 5 catalysts, those exchanged with Cu2+, Fe3+, VO2+ and Mn2+ have a relatively high activity and stability .

Key words: Transitional metal ions, Ion exchanged zeolite, MoO3/MH-ZSM-5, Methane aromatization, Benzene
