“…As is seen from Fig. 1, the yield and distribution of pyrolysis products from PW at 625 °C were similar to those found at 550 °C, which implies that PW can be sufficiently pyrolysed at 550 °C (Schwarzinger et al 2008). Likewise, the distribution of hydrocarbons from pyrolysis of HDPE at 625 °C was also similar to that found at 550 °C.…”

Pyrolysis-gas chromatography/mass spectrometry (Py-GC/MS) was employed to investigate the primary pyrolysis product distribution of the pyrolysis of wood-plastic composites (WPCs) and the mutual effects of poplar wood (PW) and high-density polyethylene (HDPE). The PW, HDPE, and WPCs were pyrolysed at 475, 550, and 625 °C. The effect of temperature on the WPC pyrolysis products was examined. The comparison of the degradation composition results for HDPE, PW, and WPCs indicated that thermal degradation of WPCs comprised individual poplar wood and HDPE pyrolytic decompositions, and the pyrolytic products of PW and HDPE did not react with each other. The experimental results demonstrate that the pyrolytic product distribution of HDPE changed apparently in the presence of PW during pyrolysis. The PW decomposed at lower temperature during pyrolysis provided radicals, enhancing the scission of polymer chains to obtain more light paraffins. Further, the proposed pathway for the evolution of the main volatile organic products was probed. This study provides insights into the fundamental mechanisms of WPC pyrolysis and a basis for developing more descriptive models of WPC pyrolysis.

“…In addition, Py-GC/MS has been successfully applied to the qualitative and quantitative analysis of WPCs, e.g. wood type, the polymer matrix, and the ratio of thermoplastic polymers and wood in WPCs (Fabiyi et al 2008;Schwarzinger et al 2008;Windt et al 2011).…”

“…Styrene can be of either biogenic or anthropogenic origin. Styrene is a major degradation product of styrene and isoprene rubbers, and styrene particles are released from tyre erosion in vehicular traffic (Fabbri et al, 2005), and from pyrolysis of polyvinylchloride (Schwarzinger et al, 2008) or cellulose (Pastorova et al, 1994).…”

“…This situation cannot occur in TGA where small amounts of material are used. In most of the studies performed with only TGA (sometimes complemented with reactor pyrolysis) no interaction or unclear minor interaction was reported between components in mixtures [13][14][15][19][20][21][22][23]. However, in most of the reactor pyrolysis studies (sometimes complemented with TGA), considerable degree of synergistic effect was reported.…”
