초록
열 중량 분석기를 이용하여, 상온에서부터 600 ℃까지 10, 20, and 30 ℃/min의 승온 속도로 바이오매스/플라스틱 혼합물의 혼합열분해를 수행하였다. 바이오매스는 폐목재 우드칩(WWC)을 사용하였고, 플라스틱은 선형저밀도 폴리에틸렌(LLDPE)을 시료로 사용하였다. LLDPE 단독 분해시 430∼550 ℃, WWC 단독 분해시는 230∼600 ℃에서 분해되었으나, 두 가지 시료를 혼합하여 혼합열분해 한 결과, WWC에 해당하는 분해 온도는 일정한 반면 LLDPE 분해구간의 분해온도가 상승하였다. 이러한 실험결과는 높은 온도범위에서 LLDPE와 WWC이 혼합열분해 되는 동안에 상호작용이 일어났음을 의미한다.
Copyrolysis of biomass/plastic mixture was carried out from room temperature to 600 ℃ with varing the heating rates of 10, 20, and 30 ℃/min using a thermogravimetric analyzer. Waste wood chip (WWC) and linear low density polyethylene (LLDPE) were selected as a biomass and plastic, respectively. Individual pyrolysis temperature ranges were 430∼550 ℃ and 230∼600 ℃ for LLDPE and WWC, respectively. For the copyrolysis of WWC and LLDPE, the decomposition temperature range of WWC was not varied, while the decomposition temperature range of LLDEP was increased to a higher temperature. The results imply that the interaction might occur between LLDEP and WWC during copyolyis of LLDPE and WWC.
