摘要

Incineration of plastic materials for the energy generation is one of the types of polymer recycling, however the composition of the atmosphere used in this process must be controlled, since the products generated during the incineration and released into the atmosphere can be harmful to environment. Combination of different polymers and the mixing of this with other municipal solid wastes can generate varied products, accentuating the toxicity of the evolved gases. Thus, in this work, mass loss, amount of main stages and the gases evolved during polyethylene (PE) and polyvinyl chloride (PVC) thermolysis, as well as the physical mixture of both polymers, were analyzed by the evolved gas analysis using hyphenated techniques Thermogravimetry and Infrared Spectroscopy. Analyzes were conducted under inert and oxidizing atmosphere and showed that the products formed in the samples thermolysis were chemically different in the two atmospheres. During the thermogravimetric analysis under oxidizing atmosphere, even O-2 is present in a significant amount, the products formed are dependent on the temperature of the thermolysis process, being able to generate carbon dioxide and carbonylated, carboxylated compounds, carbon monoxide and others products.
