Performance of Modified Mo/HZSM-5 in Methane Aromatization under Non-oxidative Condition

The catalysts with different molar ratios of Si to Al(n_(Si)/n_(Al)) of HZSM-5(Hydrogen Zeolite Socony Mobile-Five) have different catalytic performances in methane aromatization under non-oxidative conditions.At n_(Si)/n_(Al)=40,the Mo/HZSM-5 catalyst has higher selectivity and benzene formation rate and is more stable.The effects of different treatment methods on Mo/HZSM-5(w_(Mo)=0.03) are also(investigated.) Results show that the catalysts modified by alkali and subsequently treated by acid have better c...
