초록
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%.
