Pyrolysis oil is obtained by heating organic materials like waste plastics, wood and crop residues in a reactor without oxygen at around 500°C followed by cooling, separation from the aqueous phase and other processes. The market for pyrolysis oil from mixed plastics waste is growing fast driven by EU legislation and brand owner commitment. However, pyrolysis oil specifications can vary significantly depending on process and raw materials used. Typically, PyOil is a dark brown liquid that contains high levels of impurities such as oxygen, sulphur, chlorides, silicones and others. These contaminants can cause various issues in the downstream assets from fouling over corrosion to catalyst poisoning. Evonik has multiple solutions in-house to manage these issues and extensive experience in petrochemical applications.
