초록
질소 분위기의 고온(350~900 ℃)의 등온 열중량 분석기를 사용하여 도시 폐기물 폐목재의 탈휘발 특성을 측정 및 고찰하였다. 탈휘발은 온도범위 250~350 ℃에서 주로 발생하였다. 휘발분의 양은 온도가 증가할수록 증가하였으나, 527 ℃ 이상에서는 일정해졌다. 화학반응 율속의 shrinking particle model로 탈휘발반응을 잘 표현할 수 있었다. 탈휘발 활성화 에너지는 13.1~18.5 kJ/g mol이었다.
Devolatilization characteristics of municipal wood waste were measured by using an isothermal thermogravimetric analyzer(TGA) and discussed. Volatile matter was mainly released at temperatures between 250 ℃ and 350 ℃. The volatile content increased with an increase of temperature but levelled off at temperatures ≥527 ℃. The rate of devolatilization could be expressed by a shrinking particle model which was ruled by the reaction rate. The activation energy ranged from 13.1 to 18.5 kJ/g mol.
