Methane is mainly used as a fuel, but with the development of gas exploration technology, interest as a feedstock for chemical production is increasing. Non-oxidative conversion of methane, which directly converts methane without oxidants is attracting attention as a next-generation technology because of its higher carbon and energy efficiency than the existing methane conversion technology (i.e., methane reforming). However, we need to explore the challenge of controlling radical-based chemical pathways at high reaction temperatures. In this presentation, we will discuss how to efficiently produce hydrocarbons from methane by optimizing the reactivity of the catalytic iron surface and gas phase. For this, we have changed reactor parameters to elucidate the roles of each reaction phase (i.e., solid to gas and/or gas to gas). We have also performed the selective hydrogenation of C2 species from 500 to 1020 °C to find a way to minimize coke formation during the methane conversion. |
