- The catalytic performance of >Â 10Â wt% Mo/HZSM-5 was significantly improved.
- 16Â wt% Mo-doped HZSM-5 shows the best behavior in catalytic aromatization of CH4.
- Prereduction with 45Â vol% CH4/Ar/He is a highly efficient pretreatment method.
The catalytic activity and stability of Mo/HZSM-5 solid with Mo loading higher than 10 wt% in methane aromatization are significantly improved after pretreatment with a CH4/Ar/He (9:1:10, v/v) gas mixture. A 16 wt% Mo loading is found to provide the best catalytic performance for the aromatization of methane and better than previously reported in the literature (similar reaction conditions) over Mo-impregnated HZSM-5zeolites. After 30 h of continuous reaction at 700 °C and using a space velocity of 1500 ml gâ 1 hâ 1, the 16 wt% Mo-based catalyst provides an aromatic yield of 7.8% and a CH4 conversion of 9.5%.
