Effect of transition metals (Mo, Mn and Co) on mesoporous ZSM-5 catalyst activity in carbon dioxide reforming of methane

Abstract

This paper investigates the effect of transition metals (Mo, Mn and Co) on mesoporous ZSM-5 support in carbon dioxide reforming of methane reaction. The mesoporous ZSM-5 support was synthesized by micro emulsion technique and the metals were loaded by wet impregnation method. It was observed that ZSM-5 supported Co catalyst had higher surface area in comparison to other catalysts, which could favour well dispersion and wider utilization of active component. In addition, the ZSM-5 supported Co catalyst exhibited the highest methane and carbon dioxide conversions of 69 % and 65 % respectively at 850°C. The Co species were more active to decompose methane and carbon dioxide compared to Mo and Mn loaded catalysts. Hence, loading Co on mesoporous ZSM-5 produce an active catalyst in carbon dioxide reforming methane reaction.
