초록
본 연구에서는 합성천연가스(synthetic natural gas, SNG)를 생산하기 위한 공정 개발을 위해 RIST-IAE에서 제안한 공정의 4차 반응기에 대하여 합성가스(H2/CO2)를 이용하여 메탄화 반응을 수행하였다. 실험의 조건은 온도, 압력, 공간속도 등을 변화시켰으며, 이때 CO2 전환율, CH4 선택도, 반응 후 H2의 농도에 대해 고찰하였다. 그 결과 CO2 메탄화반응에 의한 CH4의 선택도는 공간속도가 낮을수록, 그리고 압력이 높을수록 증가하였다. 한편, 온도의 경우에는 320 ℃에서 최대 값을 보였다. 이러한 결과로부터 SNG 공정에 적합한 4차반응기의 최적 조건을 얻을 수 있었다.
In this work, we performed the methanation reaction using synthesis gas (H2/CO2) for the process to produce synthetic natural gas (SNG) for 4th methanation reactor in SNG process proposed by RIST-IAE. Experimental conditions were changed with temperature, pressure and space velocity. At this time, CO2 conversion, CH4 selectivity and H2 concentration after reaction were investigated. As a result, CH4 selectivity by the CO2 methanation increased with lower space velocity and higher pressure. On the other hand, in the case of temperature, the maximum value was shown at 320 ℃. From these results, it was found that the optimum condition of the fourth reactor suitable for the SNG process was obtained.
