How do you purify pyrolysis oil?

Purifying pyrolysis oil involves several steps to remove impurities and enhance its quality. Common methods include fractional distillation to separate different components based on boiling points, and filtration to eliminate solid particles. Additionally, chemical treatments such as neutralization or adsorption can be employed to reduce acidity and remove unwanted compounds. Finally, refining techniques, including hydrotreatment, may be applied to improve the oil's stability and performance characteristics.
