Re-Design Pyrolysis Reactor Prototype for the Conversion of Plastic Waste into Liquid Fuel

Abstract

Abstract In this research, a pyrolysis reactor with a capacity of 5 kg has been designed. Innovation in the pyrolysis reactor is the adsorbents that are used (lime CaCO3 + iron fiber Fe2O3) in the reactor. This study aims to determine the optimal reaction conditions. Tests carried out at 200-400°C temperature intervals and a range of 40-90 minutes. The best product is 86.40% liquid yield at 350°C with a processing time of 90 minutes. ASTM distillation studies of the oil produced showed that 67% fraction was in the range of the light naphtha, 12% fraction was in the range of heavy naphtha and 21% fraction was in the range of the medium naphtha. Comparing the physical parameters of the sample oil with standard fuels, it was observed that the fractions collected were in the range of gasoline, kerosene and diesel oil. This research contributes significantly to increasing knowledge about the feasibility of pyrolysis, providing opportunities for the recycling sector to spread take-off systems, in the Circular Economy.
