Synthesis of C2 chemicals from methane in a dielectric barrier discharge (DBD) plasma bed

초록

The direct synthesis of C<inf>2</inf> chemical directly from methane was studied by employing catalysts with ordered mesopores in a dielectric barrier discharge plasma reactor. The reaction was carried out using MgO/OMA (ordered mesoporous alumina), MgO/?-Al<inf>2</inf>O<inf>3</inf> and MgO/?-Al<inf>2</inf>O<inf>3</inf> as catalysts. When MgO/OMA was applied, it showed excellent performance in the plasma reactor using pulse-type power supply and the selectivity of C<inf>2</inf> chemicals was measured as 67%. The effects of metal oxide type, textural property of support, alumina phase and power supply type on catalytic performance were investigated especially in terms of C<inf>2</inf> chemical formation. BET (Brunauer, Emmett, Teller), X-ray diffraction, transmission electron microscope and thermogravimetric analysis were used to investigate the characterization of the catalyst before and after the reaction.
