Multidimensional GC/MS analysis of pyrolytic oils

The slow pyrolysis of pomegranate seeds: The effect of temperature on the product yields and bio-oil properties

“…Toluene, phenol, styrene, and xylene were prominent intermediate peaks in the secondary cracking regime of wood. Formation of phenols and alkyl benzenes from the pyrolysis of pomegranate seeds are in good agreement with those previous reports [16][17][18][19]. High molecular weight acids such as octanoic acids and n-hexadecanoic acid were also observed.…”

“…It is considered that degradation of lignin produced predominantly phenolic compounds. The studies related to the degradation of lignin were investigated in the previous studies [16,17]. The multidimensional gas chromatography (MDGC) technique was used to analyze pyrolytic products generated from primary and secondary pyrolysis of cellulose, lignin and sewage sludge samples [16].…”

“…The studies related to the degradation of lignin were investigated in the previous studies [16,17]. The multidimensional gas chromatography (MDGC) technique was used to analyze pyrolytic products generated from primary and secondary pyrolysis of cellulose, lignin and sewage sludge samples [16]. Lignin derived oils showed a very small distribution in the contour plot due to the relative stability of methoxy phenols and alkyl phenols produced during primary pyrolysis of lignin.…”

Qualitative and quantitative analysis of pyrolysis oil by gas chromatography with flame ionization detection and comprehensive two-dimensional gas chromatography with time-of-flight mass spectrometry

“…The results of this study indicate that more than 70% of total chromatogram peaks could be identified with GC × GC but only 47%, at best, with conventional GC. The increase in the number of identified products is due to increased number of separations [17]. Comprehensive GC × GC-FID and GC-MS analysis of pyrolysis oil and hydrodeoxygenated (HDO) oils was also reported by Marsman et al [18].…”
