Plasma-CaO Coupling for CH4-CO2 transformation into Syngas and/or Hydrocarbons Oxygenates. Catalyst Structural and Textural Modifications Under Plasma Discharge

摘要

This study shows that plasma-catalysis can be considered as an alternative method for the production of oxygenated compounds and CO2 valorization, despite the low selectivity to methanol. CaO particle size, CH4/CO2 ratio or temperature had little effect on methanol yield. However, the presence of the catalyst in the plasma discharge led to the formation of carbonate oxide, proof of the CO2 diffusion into CaO pores.
