The thermal pyrolysis of three different polyolefin plastics (HDPE, LOPE and PP) has been carried out in a conical spouted bed reactor. This technology is especially interesting because of the high selectivity to waxes due to the low residence times and high heating rates that reduce secondary reactions and increase the yield of primary pyrolysis products (waxes). These have been obtained operating at 450, 500 and 600 degrees C and a complete characterization has been carried out using different techniques, such as gel permeation chromatography (GPC), Fourier transform infrared (FTIR) spectrophotometry, simulated distillation and the measurement of heating value and melting point. Operating conditions and feed type have been observed to have a significant effect on the properties of the different waxes. The characterization has been carried out bearing in mind the potential use of waste plastic-derived waxes as a feedstock for cracking units. (C) 2011 Elsevier B.V. All rights reserved.
