Conversion of methane to more valuable chemicals has received much attention in recent years with the discovery of vast reserves of shale gas. Despite the potential importance, most catalytic methane conversions exhibit low carbon efficiency due to their high coke selectivity. Selective production of olefins and aromatics through non-oxidative methane conversion at high temperatures can be an alternative to the methane economy. In this presentation, we will discuss how we could effectively convert methane with iron based catalysts. Modifying the reaction conditions allow us to control the reaction pathways for production of olefins and aromatics. A range of products produced during direct and non-oxidative conversion of methane including C1-C5 alkanes, C2-C5 alkenes, C2 alkynes and (alkyl-) aromatics. We have prepared several types of iron catalysts to maximize catalytic reactions. Reaction measurements of the iron based catalysts at 950-1080 °C were also done to elucidate the differences in reactivity to both the gas phase and the catalytic reaction. |
