Abstract: The effects of conversion of CH4 over Mo-Ni/HZSM-5 catalysts under a non-oxidizing condition with different temperatures,different conditions of pretreatment and different loadings of Ni were investigated.The results indicate that when Ni/Mo molar ratio is 0.05,the conversion of CH4 at 973 Kcan reach 11.3%,and the selectivity of aromatic hydrocarbon can reach 97.1% It′s shown that adding a certain quantity of Ni is beneficial to the conversion of CH4,the maximun conversion of CH4 at 1023 Kcan reach 15.9%.The effect of reaction with pretreatment by using N2 is better than that in the cases of H2,CH4 or air.The results of NH3-TPD-MSshow that the centre numberes of strong acidity and weak acidity both on the Mo-Ni/HZSM-5 catalysts are more than that on the Mo/HZSM-5 catalyst.This might be one of the reasons that the activity of methane aromatization is increased over Mo-Ni/HZSM-5 catalyst.
