Abstract

Reducing the emission of carbon dioxide, which is the main contributor to the green house effect, is becoming a global hot issue. Great attention has been thus given to utilization of carbon dioxide rather than just capturing and isolating it because it could convert carbon dioxide to high-value chemicals. In this paper, recent research trends are investigated on the catalytic conversion of carbon dioxide to syngas in the context of $CH_4$, dry-reforming, trireforming, and the electro-catalytic conversion of carbon dioxide through SOFC(Solid Oxide Fuel Cell) system. Research trends for utilizing syngas to high-value-added useful products, mainly fuel such as DME(Dimethyl Ether) are also discussed.

온실 가스의 주원인인 이산화탄소 발생의 저감은 범세계적으로 중요한 문제가 되었다. 이산화탄소를 단순히 분리하고 외부와 격리시키는 것보다는 이를 이용하여 고부가가치의 화학제품으로 전환 가능하다는 점에서 이산화탄소의 자원화에 대해 많은 관심을 받고 있다. 본 논문에서는 이산화탄소의 촉매 전환을 통한 합성가스 생산의 방법으로서 이산화탄소 개질, 삼중 개질 그리고 내부 개질 고체 산화형 연료 전지(Solid Oxide Fuel Cell) 시스템과 연계하여 전기와 합성가스를 동시에 생산하는 기술로 정하고 이에 대한 최근 연구 동향을 정리하였다. 또한 합성가스로부터 Fischer-Tropsch 합성을 통한 장쇄 탄화수소 생성과 Dimethyl Ether(DME) 생성을 중심으로 한 유용한 화학제품을 생산에 관한 연구 동향을 포함하였다.
