초록
Medium-density fiberboard의 최적 열분해 조건을 찾기 위해 유동층 반응기를 이용하여 다양한 실험조건에서 급속열 분해 실험을 수행하였다. 열분해 온도를 425 ℃와 575 ℃ 사이에서 변화시켰을 때, 525 ℃에서 최대 바이오오일 수율 52 wt%를 얻을 수 있었다. 열분해 온도가 높을수록 생성되는 바이오오일의 품질이 좋은 것으로 나타났다. 높은 온도에서 열분해 반응을 수행할 경우, 상당한 양의 oxygenates 및 acids 물질들이 분해되고, 대신 aromatics와 phenolics 같은 고부가가치 물질들이 생성되었다. 기체상 생성물의 대부분은 CO와 CO2였다. 열분해 온도가 높을수록 CO와 C1-C4 탄화 수소 생성량이 많았다.
Fast pyrolysis of medium-density fiberboard was carried out using a fluidized-bed reactor under various conditions to find an optimum pyrolysis condition. When the pyrolysis temperature was varied between 425 ℃ and 575 ℃, the maximum bio-oil yield of 52 wt% was obtained at 525 ℃. The quality of the bio-oil product increased with increasing pyrolysis temperature. Pyrolysis at a high temperature removed significant amounts of oxygenates and acids, producing more valuable species such as aromatics and phenolics. The main gaseous products were CO and CO2. The yields of CO and C1-C4 hydrocarbons increased with increasing the pyrolysis temperature.
