ABSTRACT
In the process of pyrolysis, where heating occurs in the absence of oxygen, the organic compounds are decomposed generating gaseous and liquid products, which can be used as fuels and/or sources of chemicals. The thermal pyrolysis requires high temperatures, which often results in products with low quality, making this process unfeasible. Tertiary recycling of plastic waste containing Poly(vinyl chloride) releases hydrogen chloride, which causes corrosion of the pyrolysis reactor and formation of organochlorine compounds. In the pyrolysis process, the sample is heated in the absence of oxygen and the organic compounds are decomposed generating gaseous and liquid products. The pyrolysis of waste plastics involves the thermal decomposition in the absence of oxygen/air. The zeolites have a specific pore size and the access of polymer molecules to internal reactive sites of the catalyst, as well as the final products within the pores are limited by their size. Some chemical and physical characteristics of zeolites ensures them their catalytic capacity.
