Waste plastic pyrolysis oil technology

Used waste plastic pyrolysis oil recovery technologies, namely, by heating or adding a catalyst to enable decomposition of waste plastics. Monomers and polymers were, vegetable oil, gasoline and fuel oil gas, and wax. Pyrolysis of waste plastics to oil pollution on the environment not only can effectively recover energy. It can be said that the pyrolysis of waste plastics for oil and petroleum-based oil chemical industry manufacturing plastic products, reverse the process.

1, the composition of waste plastics as a result of different cleavage also vary, polyethylene (PE), polypropylene (PP) and polystyrene (PS) in the 300-400 , almost all of this decomposition. And polyvinyl chloride (PVC) in the 200-300 and 300-400 Decomposition of sub-paragraphs. Bank under the lower temperature release HCL, and produce more hydrocarbons, and then at a higher temperature a further decomposition. As the body of the melon HCL dare to have certain equipment corrosion, and impact on life and cracking catalysts and diesel, petrol quality. Thus pyrolysis of PVC raw materials in the general requirements for waste plastics content of no more than 30%.

2, a product of pyrolysis

     As a result of different molecular structure of plastics vary greatly, thus the composition of pyrolysis products and the recovery rate is not the same. General, to generate four types of thermal decomposition products: hydrocarbon gases (C1-C5), oil (gasoline carbon molecules for C5-C11, the number of diesel carbon molecules C12-C20, the number of heavy carbon molecules C20), paraffin and coke. Table 1-2 shows the typical pyrolysis of waste plastics recovery rate and the composition and content of the product.
