Waste polyvinyl chloride (PVC) is hard to treat because of Cl compound in PVC. Traditionally, treatment of waste PVC is performed through disposing in landfill and incineration. When implements the thermal disposal of the PVC, Cl is transformed to HCl and it evokes the corrosion of pipes and causes environmental problems. Pyrolysis can be a promising alternative on the aspect that Cl compounds can be controlled in the process compared with the traditional treatment of PVC. And the pyrolysis oil from PVC have a potential to be a chemical source of BTX and alternative fuel. The aim of this study was to reduce the Cl content in the pyrolysis oil. To achieve the aim of the study, pyrolysis experiments of PVC were performed to determine the effect of temperature on pyrolysis oil properties. To identify the thermal degradation characteristic of PVC, thermogravimetric analysis (TGA) was also conducted. According to TGA results, thermal degradation presented in the range of 200-800 ℃ and Cl releases among 200-350 ℃. To obtain the low Cl containing oil, 2-step pyrolysis was performed. |
