Abstract
The use of plastics is increasing, and the disposal of plastic waste is becoming a serious problem. Plastic wastes are not only poorly decomposable but also cause various pollution problems. Therefore, effective treatment of waste plastics is needed. In the case of waste plastics whose constituents are not uniform, it is best to make hydrocarbons using pyrolysis reactions.
In this paper, the pyrolysis characteristics of waste plastics were investigated using a fluidized bed pyrolysis reactor. First, thermal decomposition characteristics and trends of the waste plastics were analyzed through TGA, elemental analysis, proximity analysis of samples and XRF (X-ray fluorescence) analysis of ash. In the pyrolysis fluidized bed reactor(Fig1), the effects of various reaction parameters, like reaction temperature, the feed rate of waste plastics, and residence time after the reaction was investigated. And the complexed organic compounds between the product oils on the different experimental parameters and a detailed analysis of the oils were also investigated.
