Liquid fuel production from high density polyethylene plastic waste

Abstract

This research aims to determine the effect of heat exchanger diameter variations on the volume and physical properties of fuel derived from plastic waste. The plastic waste is converted using the thermal cracking method, which involves heating the raw material without oxygen. This process produces charcoal and oil from the gas condensation in the heat exchanger. The type of plastic used is High-Density Polyethylene (HDPE) waste. The variations of heat exchanger diameter used are 1/2inch, 3/4 inch, and 1 inch. The physical properties investigated include density, viscosity, and heating value. From the test results, it was found that density of the oil fuel produced from plastic waste decreased with increasing heat exchanger diameter. However, the volume and heating value of the fuel produced increased. Generally, the physical properties of plastic pyrolysis oil produced from the thermal cracking process of plastic waste resemble those of gasoline
