How to Improve the Quality of Plastic Pyrolysis Oil?

Plastic pyrolysis technology has emerged as a promising solution for plastic recycling. However, the quality of plastic pyrolysis oil often varies, impacting its usability and market value. DOING, a leading manufacturer of plastic pyrolysis machine, has several key strategies to significantly enhance the quality of pyrolysis oil, making it a more viable alternative fuel source and broadening its potential applications.

Plastic pyrolysis oil

Raw Material Selection and Pre-treatment

The foundation of high-quality pyrolysis oil lies in the selection and pre-treatment of raw materials. Using high-purity, single-type plastics as feedstock is crucial, as mixed or contaminated plastics can introduce impurities and reduce oil quality. Proper sorting ensures a purer final product.

General plastic pyrolysis oil yield

Cleaning: Thoroughly cleaning the plastic feedstock to remove contaminants such as metals, glass, and dirt is essential. This step minimizes the presence of ash and non-volatile residues in the final oil.

In addition, it is best to keep waste plastic raw materials dry. For example, before storing the washed plastic materials in the paper mill, it is usually recommended to store them in the sun. This will increase the efficiency of the overall scrap plastic pyrolysis process, reduce energy consumption, and improve the quality of plastic pyrolysis oil.

Plastic Pyrolysis Oil Distillation

After extracting plastic pyrolysis oil from pyrolysis machine, distillation is a critical step in improving oil quality. By separating the oil into different fractions based on boiling points, distillation not only enhances the usability of the oil for various applications but also removes moisture and volatile organic compounds. This process ensures that the final product is more stable and suitable for industrial use. DOING has advanced waste pyrolysis oil distillation machines to help you get higher quality diesel, which can be used in a wide range of applications, such as boilers, generators, burners, agricultural machinery, construction machinery, and ship engines.

Purification: Generally, after the previous process, you have already obtained good quality diesel. If you want to get better quality, light yellow color diesel, then you can add a purification system such as white clay decolorization equipment to further purify the diesel.

Blending

Blending pyrolysis oil with conventional fuels or other bio-oils can help adjust its properties to meet specific requirements. This approach enhances the performance of pyrolysis oil in combustion engines and broadens its application scope. For example, blending with diesel can improve the combustion efficiency and reduce emissions.

Improving the quality of plastics pyrolysis oil is essential for maximizing its usability and market value. By focusing on raw material selection, distillation, and blending, manufacturers can significantly enhance the quality of pyrolysis oil.
