“…• C) an oil consisting of 40% of BTX (benzene, toluene and xylenes), was obtained [77]. When PS and PMMA were used as feed, actual depolymerization towards the constituting monomers took place since they were obtained with high selectivity (61% of styrene and 97% of methyl methacrylate).…”

“…Ma et al [22] compared the fast pyrolysis of PVC at 600 and 800 °C, and found that more CH4, C2H4, C2H6, C3H6, and C3H8 were generated at 800 °C, which was consistent with the results in this study. The enhancement of gas production with the increase of pyrolysis temperature has been attributed to the promoting of C-C cracking reactions [23,24].…”

Municipal solid waste (MSW) contains significant amounts of polyvinyl chloride (PVC). The reactivity of PVC may form polycyclic aromatic hydrocarbons (PAHs) during the pyrolysis of MSW, which can become a key challenge during the development of pyrolysis technologies.However, there is very limited work in relation to the influence of pyrolysis process conditions in terms of temperature and heating rate on PAHs formation during pyrolysis of PVC. In this work, the formation of 2-4-ring PAHs from the pyrolysis of PVC at temperatures of 500, 600, 700, 800, or 900 °C and at fast and slow heating rates was investigated under a N2 atmosphere in a fixed bed reactor. With the increase of temperature from 500 to 900 °C, HCl yield decreased from 54.7 to 30.2 wt.%, while the yields of gases and PAHs in the tar increased. Slow pyrolysis generated higher HCl yield, and lower gas and tar yield than fast pyrolysis; the PAH yield obtained from the slow pyrolysis was much lower compared to fast pyrolysis. The results suggest that for fast pyrolysis, the dehydrochlorination of the PVC might be incomplete, resulting in the formation of chlorinated aromatic compounds.
