Cell phone case waste, as one of the leading sources of e-waste, can have serious consequences for both humans and the environment. It should be processed or converted into something more useful. The goal of this research is to look into the effect of particle size on the production of liquid fuels from cell phone case waste via pyrolysis and distillation processes. In each experiment, approximately 150 g of cell phone case waste was pyrolyzed at 450°C. At a weight ratio of 2:1, the sample was mixed with carbon materials as an absorber. The pyrolysis processes were carried out at various particle sizes ranging from bigger to smaller particles. The produced liquid oil was then distilled to obtain diesel fractions, which were then analyzed to determine fuel properties. The results revealed that particle size had an effect on the yield of liquid oil produced by pyrolysis of cell phone case waste. Among the particle sizes tested, bigger particles of 2-15 mm produced the most liquid oil, while smaller sizes yielded the most gaseous products. The results also showed that the diesel fraction obtained from the distillation of liquid oil has physical properties that are very different from diesel oil. This is possible because its compound was dominated by aromatic hydrocarbon compounds, specifically phenol and its derivatives. Therefore, the diesel fraction from cell phone case waste is more recommended for furnace fuel or only as a fuel additive, rather than a diesel fuel mixture. © 2023 American Institute of Physics Inc..
