본 연구에서는 열중량분석법을 이용하여 회분식 반응기에서 승온속도를 0.5, 1.0 및 2.0 ℃/min로 변화시키면서 polystyrene의 열분해반응 속도실험을 수행하였다. 미분법을 이용하여 polystyrene의 열분해 전환율이 1%에서부터 100%일 때까지의 활성화에너지 및 반응차수를 구하였다. 반응이 급격하게 진행되는 구간에서 활성화에너지는 점진적으로 증가하였다. 회분식반응기에서 반응온도를 380-400 ℃로 변화시키면서 60분동안 열분해반응 실험을 수행한 결과 반응온도가 증가할수록 생성된 열분해 오일의 양은 증가하지만 생성물의 탄소수 분포는 거의 일정하게 나타났으며, styrene 단량체와 이량체에 해당하는 탄화수소화합물의 선택성이 매우 높게 나타났다.
Kinetic tests on pyrolysis of polystyrene 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 until the conversion increased to a certain extent. Polystyrene was thermally cracked in a semi-batch reactor at 380-400 ℃ for 60 minutes. As the reaction temperature increased, the yields of product oil increased but those of light hydrocarbon oil were almost constant. Also, the selectivity of hydrocarbons corresponding to the styrene monomer and dimer was very high.
