내부순환유동층 반응기에서의 폐타이어 가스화 특성
Gasification Characteristics of Waste Tire in an Internally Circulating Fluidized Bed
이승엽, 김용전, 김상돈
오리피스 형태의 드래프트 관을 갖는 내부순환유동층 반응기에서 폐타이어의 가스화 반응을 수행하였다. 대기압하에서 반응온도(750-900℃), 수증기/탄소 비(0.94-1.67), 산소/탄소 비(0.23-0.47)의 변화에 따른 생성가스의 조성, 수율, 발열량, 탄소전환율, cold gas efficiency 등을 측정하였다. 애뉼러스 영역의 생성가스는 21.5-39.2% H2, 3.8-12.2% CO, 34.8-19.6% CO2, 12.5-15.3% CH4, 25.0-15.0% C2H4, 0.4-0.2% C2H6, 1.7-0.1% C3H6의 조성(vol%, N2 free)을 가진다. 애뉼러스 영역의 생성 가스 수율은 0.389-0.490 m3/kg tire, 발열량은 24.5-21.7 MJ/m3, 탄소 전환율은 27.2-34.4%, cold gas efficiency는 46.9-51.6%의 값을 나타내었다.
Waste tire was gasified in an Internally Circulating Fluidized Bed (ICFB) with draft tube(orifice type). The effects of reaction temperature(750-900℃), steam/carbon ratio(0.94-1.67) and oxygen/carbon ratio(0.23-0.47) on composition, gas yield, calorific value, carbon conversion and cold gas efficiency of the product gas have been determined. The product gas in the annulus region contains 21.5-39.2% H2, 3.8-12.2% CO, 34.8-19.6% CO2, 12.5-15.3% CH4, 25.0-15.0% C2H4, 0.4-0.2% C2H6, 1.7-0.1% C3H6(vol%, N2 free basis) with a gas yield of 0.389-0.490 m3/kg-tire, calorific value of 24.5-21.7 MJ/m3, carbon conversion of 27.2-34.4% and the cold gas efficiency of 46.9-51.6%.
