Plastic pyrolysis is a distillation process that allows plastic waste to be converted into fuel. Plastic waste is heated above 400°C in a first tank into a gas. Depending on condensation (cooling) temperatures, several types of fuel are produced : - between 390 and 170°C, the gas condensates into diesel fuel. - between 210 and 20°C, the gas condensates into gasoline. - below 20°C, there remains non-condensable residual gas that can be burned to provide heat to the process.
In this prototype, we are only using polypropylene (PP) and/or high density polyethylene (HDPE) and low density (LDPE). Please note that using mostly polypropylene will produce more gasoline, while using mostly polyethylene will produce more diesel fuel. It is however possible to mix both.
