가스 하이드레이트 형성 원리를 이용한 철강공정 배기가스 중 CO2 분리기술에 대한 최근 연구 동향

Gas hydrates are crystalline solids composed of water and gas molecules. Water molecules are linked through hydrogen bonding and create cavities(host lattice) that can capture a large variety of guest molecules under appropriate conditions, generally high pressure and low temperature. Recently, many researchers try to apply gas hydrates to industrial processes to capture greenhouse gases due to the facts that the process is eco-friendly and target gas molecules can be preferentially captured. In this paper, we introduced recent studies on and - mixture hydrates to evaluate the feasibility of industrial application of gas hydrate technology to capture process. Specifically, we put emphasis on the technical feasibility of separation in steel industry using gas hydrate formation principles.
