Abstract

In this study, dynamic simulation of membrane reactor was performed for water gas shift reaction and temperature, hydrogen concentration, etc. were investigated as a function of time and position. Simulation results indicated that differences of hydrogen concentration, hydrogen partial pressure, and temperature in the radial direction, were larger in the entrance than in the exit. In addition, the hydrogen flux was the largest in the entrance, where the hydrogen partial pressure difference was the largest, and the conversion of carbon monoxide in the exit was about 0.65.

본 연구에서는 Water Gas Shift (WGS) 반응이 일어나는 분리막 반응기 (MR) 대상공정에 대해서 동적모사 (dynamic simulation)를 실시하고 시간과 위치에 따른 온도 및 수소 농도 변화 등을 살펴보았다. 모사 결과에 의하면 도입부에서 반경방향으로의 수소 농도, 수소 분압 및 온도차가 가장 컸으며 출구에서 가장 작았다. 또한, 수소분압의 차이가 가장 큰 도입부에서 수소의 flux가 가장 크게 나타나며 출구에서 일산화탄소의 전환률은 0.65였다.
