1. 서론
최근, 전 세계는 온실가스 배출 감축의 중요성을 깊이 인식하고 있으며 기후 온난화로 인한 환경 재난을 막기 위해 다양한 노력들을 기울이고 있다. 이산화탄소 (CO_2) 배출 감축 및 저감 기술로는 에너지절약, 고효율 에너지 이용 기술, 신에너지 및 청정에너지와 같은 비화석연료 사용, 재생에
coal’s temperature underground reaches about 122 degrees Fahrenheit, and after a sufficient amount of time, most of the biogenic methane has been generated. Also at this time nearly two thirds of the moisture has been expelled and the coal has reached a rank of subbituminous (Rightmire, 1984).
After the coal’s temperature has exceeded 122 degrees Fahrenheit due to the geothermal gradient and
Coalbed methane is a form of natural gas that is trapped within coal seams.
In recent decades it has become an important source of energy in United States, Canada, and other countries.
It is called sweet gas.
Enhanced coal bed methane recovery
is a method of producing additional coalbed methane from source rock.
This technique may be used in conjunction with carbon capture

1.1. IGCC
가스화 복합발전기술(IGCC:Integrated Gasification Combined Cycle)은 석탄, 중질잔사유 등의 저급원료를 고온·고압의 가스화기에서 수증기와 함께 한정된 산소로 불완전연소 및 가스화시켜 일산화탄소와 수소가 주성분인 합성가스를 만들어 정제공정을 거친 후 가스터빈 및 증기터빈등
