【 摘 要 】

The widespread use of plastics in the community has resulted in increased waste. Plastics are synthetic polymers that are formed as products of fossil fuel and that are difficult to decompose naturally. This research used the pyrolysis process on a fixed bed reactor to utilize plastic waste especially polystyrene type. The raw materials in this study are high impact polystyrene (HIPS), expanded polystyrene (EPS) and oriented polystyrene (OPS). The ratios of raw material (HIPS: EPS: OPS) are 1:0:0, 0:1:0, 0:0:1, 2:1:1, 1:2:1, 1:1:2, and 1:1:1 also heating rates at 2 °C/min, 4 °C/min, 6 °C/min, 8 °C/min and 10 °C/min. The highest yield at 0:0:1 ratio and with a heating rate of 10 °C/min. The heating rate of 10 °C/min generated the highest amount of yields in general at each ratio. Analysis of the compound using Gas Chromatography-Mass Spectrometry (GC-MS). The compound was dominated by aromatic hydrocarbons, with dominant compounds of ethylbenzene, p-xylene, styrene, 2-phenyl- 1propene, 1,3-diphenyl propane and methyl styrene.
