Hidrocarburos C6−C10 a partir de polietileno residual

In this research work, combustible liquid hydrocarbons (gasoline) are obtained with a yield of 90% by means of pyrolysis of high-density polyethylene (HDPE) at 390 ± 5 °C over α−PbO catalyst. The catalytic mass is varied in 10, 15, 20 and 40% w/w using 10 g of HDPE for each experiment. The α−PbO is synthesized at 550 °C in an air atmosphere for 1 hour. Liquid products are characterized by Fourier transform infrared spectroscopy (FT-IR) and gas chromatography and mass spectrometry (GC/MS). The experimental optimal ratio of HDPE/α−PbO for the conversion of residual polyethylene is 20% α−PbO. The analyzes by FT-IR and GC/MS, allow to confirm that the liquids obtained correspond to hydrocarbons with chains in a range of 6 to 10 carbons (C6–C10) and contain an average heat of combustion of 10.9492 kcal/g with potential application as alternative fuels.
