“…The results of Li et al (2013) show that the pyrolysis of cellulose generated more naphthalene (3.87%) than the pyrolysis of LDPE (0.79%) in the presence of ZSM-5 catalyst using a Py-GC/MS reaction system at 650°C. McGrath et al (2003) investigated the formation of PAH from the pyrolysis of cellulose over the temperature range of 300-650°C.…”

“…The pathway to PAH formation in the 300-650°C temperature range was believed to proceed via the carbonization process where the solid residue underwent a chemical transformation and rearrangement to give a more condensed polycyclic aromatic structure. However, it appears that most of the work reported in the literature has focused on only a small number of components (Wu et al, 2013;Onwudili et al, 2009;Li et al, 2013;Marsh et al, 2004;McGrath et al, 2003). There are few reports investigating the release of PAH from a large range of MSW fractions.…”

“…Therefore, understanding the emissions of PAH is an important research topic. There have been investigations of tar production, including PAH, from pyrolysis of biomass or MSW (Wu et al, 2013;Onwudili et al, 2009;Li et al, 2013;Marsh et al, 2004;McGrath et al, 2003). For example, we have previously studied the pyrolysis of xylan, cellulose and lignin in a two-stage reactor system with or without the presence of nickel-based catalysts.…”

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.

“…1 Recent research has shown that co-feeding of plastics during biomass pyrolysis may provide a viable means to improve biomass conversion. 2 However, there are several challenges for the copyrolysis of biomass and plastics towards large-scale development; for example, the formation of polycyclic aromatic hydrocarbons (PAH) in the product oil. 3 PAH are a group of semi-volatile hydrocarbons, which may cause teratogenesis, cancer or mutations if absorbed by the human body.…”

RSC Advances RSCPublishing ARTICLEThis journal is © The Royal Society of Chemistry 2013 J. Name., 2013, 00, 1-3 | 1 The interactions of polyvinyl chloride (PVC) and biomass components (hemi-cellulose, cellulose and lignin) during fast pyrolysis were investigated at 800 °C in a fixed bed reactor. The interactions of PVC and biomass components decreased the HCl yield and increased the tar yield significantly. During the co-pyrolysis of PVC with the biomass components, most polycyclic aromatic hydrocarbons (PAH) components were decreased compared with the calculated proportion results. The mechanism of the interactions may be that in the fast pyrolysis process, the processes of dehydrochlorination and chain scission occur in a very short time. Biomass materials and/or bio-char can act as catalysts which inhibit the dehydrochlorination process or promote the chain scission of PVC. Therefore, the dehydrochlorination process might not be completed, resulting in the production of chlorinated oil compounds. Thus, the HCl yield is reduced and PAH concentrations are decreased during the co-pyrolysis of PVC and biomass.

Catalytic pyrolysis of Geodae-Uksae 1, a kind of miscanthus found in Korea, was carried out over mesoporous MCM-48 catalysts. For rapid product analysis and catalyst evaluation, pyrolysis-gas chromatography/mass spectrometry was used. X-ray diffraction, nitrogen sorption, pyridine adsorbed Fourier transform infrared, and NH3 temperature programmed desorption were utilized to analyze the properties of the catalysts. Compared to non-catalytic reaction, catalytic upgrading over mesoporous Al-MCM-48 catalysts produced a higher-quality bio-oil with a high stability and low oxygen content. Al-MCM-48 exhibited higher deoxygenation ability than Si-MCM-48 due to its higher acidity.
