열중량 분석법을 이용하여 반 회분식 반응기에서 승온속도를 0.5, 1.0 및 2.0 ℃/min로 변화시키면서 polypropylene의 열분해반응 속도실험을 수행하였다. 미분법을 이용하여 polypropylene의 열분해 전환율이 1%에서부터 100%일 때까지의 활성화에너지 및 반응차수를 구하였다. 반응이 급격하게 진행되는 구간에서 활성화에너지는 208-288 kJ/mol까지 점진적으로 증가하였으며 반응차수는 0.01이었다. 반 회분식 반응기에서 반응온도를 410-430 ℃로 변화시키면서 60분 동안 열분해반응 실험을 수행한 결과 반응온도가 증가할수록 생성된 열분해 오일의 양은 증가하지만 생성물의 탄소수 분포는 거의 일정하게 나타났으며, 특정한 탄화수소화합물에 대한 선택성은 나타나지 않았다.
Kinetic tests on pyrolysis of polypropylene were carried out by thermo gravimetric technique heating the sample at the rates of 0.5, 1.0, 2.0 ℃/min in a stirred batch reactor. The activation energy and the reaction order were determined at conversions from 1 to 100%. The activation energies increased slowly from 208 kJ/mol to 288 kJ/mol and the reaction order was 0.01. Polypropylene was thermally cracked in a semi-batch reactor at 410-430 ℃ for 60 minutes. As the reaction temperature increased, the yields of product oil increased. However, the selectivity of specific hydrocarbons was not observed.
