The pyrolysis of waste plastics is mainly a gasification process and an oiling process, but it is preferable to recover carbonized substances for wastes such as tires or polyvinyl chloride, polyvinyl alcohol, polyacrylonitrile, and some thermosetting resins. Even in some gasification and oilification processes, some carbonized materials are produced. In most cases, they are by-products and can be used as a heating fuel in converters, vertical furnaces, double-column circulation, Pyrox series or flash retorting. Provide the necessary heat. The carbonization-based pyrolysis system includes a single-column fluidized bed, a converter, a moving bed, and a flash retorting process.

Generally speaking, when the waste is heated and fractionated, the pyrolysis product is related to temperature, and when the decomposition temperature is low, the amount of oil and carbide is generated. The ratio of gas, oil and carbide in the product is greatly affected by the composition of the raw materials. The amount of paper and cellulose in the raw material is increased, and the amount of carbide formed is increased, and may even be greater than the production of gas and oil. These carbides have a calorific value between 16744 and 20930 kJ/kg and can be used as a solid fuel. Because of its low density and high ash and heavy metal content, efficient and non-polluting combustion methods are required.
