Aromatic Light Hydrocarbon Fuel Generation from Municipal Polystyrene (PS) Waste Plastic by Using Low Temperature Fractional Distillation Process

摘要

Everyday the use of plastic is increasing because plastic has light weight and durability. After use, all plastics are thrown into garbage station because some plastic are one-off and creating plastic garbage. Worldwide PS waste plastic is generating 9-10%. Polystyrene plastic formula is C8H8 and this plastic has benzene compound. Thermal degradation processes PS waste plastic breakdown long chain to short chain hydrocarbon without using any kind of catalyst. Polystyrene waste plastic to light fractional fuel production processes was two steps process. 1st step process temperature range was 100-400 ºC for polystyrene waste plastic to polystyrene fuel production. 2nd step process was polystyrene fuel into light fractional aromatic hydrocarbon fuel production processes and temperature range was 40-60 ºC. Light fractional aromatic hydrocarbon fuel separation done by fractional distillation column process. 1st step PS waste plastic to liquid fuel density is 0.88 gm/ml and 2nd step light fractional liquid fuel density is 0. 84 gm/ml. Produced fuel was analyzed by Gas Chromatography and Mass Spectrometer, Fourier Transform Infrared Spectrometer and Differential Scanning Calorimeter to determine liquid fuel compound structure, fuel band energy and fuel boiling point.
