초록

본 연구에서는 하수슬러지의 열분해로 촤를 제조하였고, 열분해 반응 조건이 슬러지 촤의 특성에 미치는 영향을 조사하였다. 열분해 온도가 300 ℃에서 800 ℃로 증가함에 따라 슬러지 char의 비표면적은 증가하였으나, 700 ℃에서는 일시적으로 감소하였다. 열분해 속도는 char의 비표면적과 기공부피에 미치는 영향이 크지 않은 것으로 나타났다. 반면, 열분해 반응시간이 증가함에 따라 비표면적과 기공부피는 증가하였으나, 평균 기공크기는 감소하는 결과를 나타내었다.

In this study, char was produced via pyrolysis of sewage sludge and the effects of reaction conditions(temperature, heating rate, reaction time) on characteristics of char were investigated. As temperature increased from 300 ℃ to 800 ℃, the surface area of sludge char increased in general but decreased at 700℃ temporarily. The effect of heating rate on specific surface area and pore volume of char was not large. Meanwhile, specific surface area and pore volume increased with reaction time but average pore diameter decreased.
