“…It can be seen that the proportion of aromatics increases with pyrolysis temperature, which is in agreement with the results obtained by other researchers [8,11,25,[37][38][39]. The formation of aromatics at the expense of aliphatics when temperature is raised has been verified by several researchers [41][42][43] in studies on pure hydrocarbon compounds. Lucchesi and Maschio [25] found an increase in oil aromaticity with temperature, by studying the H/C ratio.…”

“…PAH of the pyrolysis of PE are formed through secondary reactions via Diels-Alder type reactions involving alkenes and di-alkenes to form benzenes (Cypres, 1987;Williams and Williams, 1999;Depeyre et al, 1985;Fairburn et al, 1990). It should be noted that formation of styrene and phenylacetylene from aliphatic species by reactions R3 and R4 cannot be neglected (Shulka and Koshi, 2012).…”

Polycyclic aromatic hydrocarbons (PAH) formation from the pyrolysis of different municipal solid waste fractions

The formation of 2-4 ring polycyclic aromatic hydrocarbons (PAH) from the pyrolysis of nine different municipal solid waste fractions (xylan, cellulose, lignin, pectin, starch, polyethylene (PE), polystyrene (PS), polyvinyl chloride (PVC), and polyethylene terephthalate (PET)) were investigated in a fixed bed furnace at 800 °C. The mass distribution of pyrolysis was also reported. The results showed that PS generated the most total PAH, followed by PVC, PET, and lignin. More PAH were detected from the pyrolysis of plastics than the pyrolysis of biomass. In the biomass group, lignin generated more PAH than others. Naphthalene was the most abundant PAH, and the amount of 1-methynaphthalene and 2-methynaphthalene was also notable.Phenanthrene and fluorene were the most abundant 3-ring PAH, while benzo[a]anthracene and chrysene were notable in the tar of PS, PVC, and PET. 2-ring PAH dominated all tar samples, and varied from 40 wt.% to 70 wt.%. For PS, PET and lignin, PAH may be generated directly from the aromatic structure of the feedstock.

“…Similar observations have been reported for other hydrocarbons also. For instance, in the pyrolysis of nhexadecane, the observed activation energies did not vary much at different temperature and pressure conditions: 238.5 kJ mol À1 at 873-1123 K and 0.1 MPa (Depeyre et al [41]); 246.8 kJ mol À1 at 673-713 K and 2 MPa (Blouri et al [30]) and 255.2 kJ mol À1 at 653-723 K and 13.9 MPa (Khorasheh and Gray [32]). The value of the rate constant (k) was calculated at a fixed temperature of 833 K and different pressures, and is reported in Table 2.…”
