Abstract
본 연구는 석탄액화와 가스화시 많이 발생하는 방향족탄화수소인 tetralin과 α-tetralone을 포함한 이산화탄소와의 삼성분계의 액상에 대한 상평형과 이성분 이산화탄소-α-tetralone계의 고압상평형 및 혼합물 밀도데이터를 얻기 위해 상평형실험을 수행하였다. 이산화탄소-α-tetralone계는 온도 313.2K, 343.2K 그리고 373.2K에서 압력을 3-5MPa씩 증가시키면서 30MPa 근처까지 실험을 수행하였으며, 삼성분계인 이산화탄소-α-tetralone-tetralin계의 상평형실험은 343.2K에서 실험을 수행하였다. 이 때 압력을 2-4MPa씩 증가시키면서 각각의 압력에서 조성을 변화시켜 혼합물임계점 근처까지 실험을 수행하여 액상에서의 고압상평형데이터를 얻을 수 있었다.
High pressure vapor-liquid equilibrium data for binary and ternary including supercritical carbon dioxide with tetralin and α-tetralone of aromatic hydrocarbon were measured. The binary vapor-liquid equilibrium and mixture density data of carbon dioxide-α-tetralone system were obtained at temperature of 313.2 K. 343.2 K and 373.2 K and pressure from 5 MPa to 30 MPa. The liquid phase of the experimental ternary phase equilibrium data of carbon dioxide-α-tetralone-tetralin system was investigated at temperature of 343.2 K and pressure from 6 MPa to near mixture critical pressure.
