Here, a non-thermal plasma-catalytic methane dehydroaromatization process is presented, where we show that this chemistry can be performed at lower bulk gas temperatures, compared to the high temperatures required for methane conversion under thermal catalytic conditions. We observed that the bulk gas temperature directly influences the behavior of the plasma discharge, and led to lower methane conversions when catalysts were absent. However, incorporation of Mo/H-ZSM-5 in the plasma discharge significantly enhances methane conversion under these conditions, while shifting the product distribution toward the formation of aromatics. This presentation will highlight our current understanding of this plasma-catalytic methane dehydroaromatization mechanism and how plasma stimulation can facilitate methane dehydroaromatization pathways at lower reaction temperatures over a Mo/H-ZSM-5 catalyst.
