Abstract

CARNEIRO, Débora da S.  and  MARQUES, Mônica R. da C.. Co-pirolysis of Polyethylene Waste with the Campos Bacia Heavy Oil. Polímeros [online]. 2011, vol.21, n.5, pp. 347-352.  Epub Dec 13, 2011. ISSN 0104-1428.  http://dx.doi.org/10.1590/S0104-14282011005000074.

In this study, four mixtures of LDPE post consumer with heavy gas from the Campos Basin, in different proportions, were subjected to pyrolysis in an inert atmosphere at 550 °C. The pyrolytic liquids were characterized by gas chromatography coupled to mass spectrometry (GC/MS). Pyrolysis of pure diesel supplied large amounts of waste oil and only 4% in the range of diesel. On the other hand, the pyrolysis of LDPE mixture of diesel (at the ratio 1/0,5 m/m) provided 20% of light hydrocarbons with high production of pyrolytic oil (96%). The formation of high levels of paraffins and olefins in the range of diesel oil during the co-pyrolysis suggests a promising technology for recycling of plastic waste.

Keywords : Co-pyrolysis; plastic waste; polyethylene.
