초록
유전체 장벽 방전 반응기에서 규칙적인 메조기공 갖는 촉매를 사용하여 플라즈마 에너지를 이용한 메탄의 직접전환 반응 연구를 수행하였다. 촉매는 MgO/OMA (ordered mesoporous alumina), MgO/γ-Al2O3와 MgO/α-Al2O3를 사용하여 반응하였다. Pulse 고전압을 이용한 플라즈마 반응기에서 촉매 MgO/OMA를 사용하였을 때 C2 화합물의 선택도는 67%로 최고의 성능을 나타내었다. 금속산화물 종류, 규칙적인 메조기공 구조, 알루미나의 상변화 그리고 전원공급방식에 따른 효과를 고려하여 반응기 성능 및 생성물 분포를 비교하였다. BET (Brunauer, Emmett, Teller), X 선 회절, 주사전자현미경, 열 무게 분석으로 촉매의 반응 전후의 특성을 분석하였다.
The direct synthesis of C2 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/γ-Al2O3 and MgO/α-Al2O3 as catalysts. When MgO/OMA was applied, it showed excellent performance in the plasma reactor using pulse-type power supply and the selectivity of C2 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 C2 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.
