Abstract
본 연구에서는 열중량분석법을 이용하여 1기압과 2기압에서 승온속도를 0.5, 1.0 및 2.0℃/min로 변화시키면서 폐윤활유의 열분해반응 속도 실험을 수행하였다. 전환율이 1%에서부터 100%일 때까지의 활성화에너지 및 반응차수를 구하였으며 반응기 급격하게 진행되는 구간에서 활성화에너지는 1기압일 대 점진적으로 증가하였고 2기압에서는 거의 변화가 없었다. 회분식 반응기에서 반응압력이 1기압과 2기압일 때 반응온도를 400-460℃로 변화시키면서 2시간동안 열분해반응 실험을 수행한 결과 반응온도가 증가할수록 생성된 열분해 오일의 양은 증가하지만 탄수소가 낮은 탄화수소화합물의 양은 감소하였다. 회분식반응기에서 폐윤활유의 최적 열분해 반응조건은 440℃, 1기압이였다.
Kinetic tests on pyrolysis of waste lubricating oil were carried out with thermo gravimetric technique at the heating rates of 0.5, 1.0, 2,0℃/min and pressure of 1 and 2 atm. The activation energy and the reaction order were determined at conversions of 1 to 100%. The activation energies were increased slowly at 1 atm, but took a constant value until a given degree of conversion at 2 atm. Waste lubrication oil was thermally cracked in semi-batch reactor of 400-460℃ at 1 and 2 atm for 2 hours. As the reaction temperature increased, the yields of products oils increased, but the product of light hydrocarbon oils decreased. The optimum temperature of pyrolysis of waste lubricating oil was 440℃ at 1 atm.
