ScholarBank@NUS Repository. | Abstract: | The effects of HZSM5 Si/Al ratio, cobalt additive and HCl-acidified pretreatment on methane conversion and selectivity to aromatics have been investigated for non-oxidative conversion of methane to aromatics. The HZSM5 (E) with low Si/Al ratio (Si/Al = 20) has better methane conversion and benzene selectivity than HZSM5 (D) (Si/Al = 55). The synergistic effect is exhibited in 3% Mo-1% Co-HCl/HZSM5 (E) catalyst, on which a high methane conversion of 10.7% can be achieved, in comparison with 5.3% methane conversion on 3% Mo/HZSM5 (E). The catalysts have been characterized by XPS and the reaction mechanism is discussed. © 2001 Published by Elsevier Science B.V.
