Kinetic tests on the pyrolysis of waste ship lubricating oil were carried out by thermogravimetric analysis (TGA) at heating rates of 0.5, 1.0, and 2.0 ℃/min. Pyrolysis started at 250 ℃ and the main decomposition temperature region of the waste ship lubricating oil was between 280 and 430 ℃ at each heating rate. The corresponding kinetic parameters, activation energy and free exponential factor, were determined by differential the method over the degree of conversions. The activation energies were between 121 and 139 kJ/mol as the conversion of the pyrolysis reaction increased from 5% to 95%. Free exponential factor was in the range of 107~ 108when the activation energy distribution was almost constant. Waste ship lubricating oil was pyrolyzed in a micro-scale tubing bomb reactor between 420 ℃ and 440 ℃ for 60 min. As the reaction temperature increased, the yield of pyrolyzed gas increased. The selectivity of specific hydrocarbons was not observed and the carbon number distribution of the pyrolyzed oil was below C19.

열중량 분석기(TGA)를 이용하여 승온속도를 0.5, 1.0 및 2.0 ℃/min으로 변화시키면서 선박용 폐윤활유에 대한 열분해반응 특성 연구를 수행하였다. 분해반응은 250 ℃부터 시작되었으며, 각각의 승온속도에서 열분해반응은 280 ~ 430 ℃구간에서 급격하게 진행되었다. 미분법으로 열분해반응 활성화에너지 및 빈도인자를 구하였다. 열분해반응 전환율이 5 ~ 95%일 때 활성화에너지는 121 ~ 139 kJ/mol내에 분포하였다. 활성화에너지의 변화가 거의 없는 구간에서 빈도인자의 차수는 107~108이내의 값을 나타냈다. 미분반응기를 이용하여 반응온도 420 ~ 440 ℃구간에서 반응시간 60 min동안 열분해반응 실험을 수행한 결과 온도가 증가할수록 생성된 열분해 가스의 양은 증가하였다.
