“…It is suggested, therefore, that the pyrolysis oil from these experiments consists of two types of material, conventional molecular species and three-dimensional species. In the case of biomass oil and the blend oil, the latter type of material is possibly an oxygenated oligomer as suggested from analysis of biomass smoke [22].…”

“…Therefore, ethylene is mainly converted to these compounds. The acetylene formed, that is considered the main soot precursor [1,18,22,27,28], would react further to produce soot and hydrogen [4,29].…”

“…Pyrolysis 79 (2007) 244-251 same well-controlled conditions. In the literature only a few studies related to this topic have been found, and mainly carried out under flame conditions [14,22]. Therefore, in this work it has been considered interesting to study the formation of soot from two different hydrocarbons: acetylene and ethylene, which are considered as important soot precursors.…”

“…It has been applied to BC previously [26][27][28][29][30][31], and the relationship between pyrolysis fingerprint and BC degradability was recently demonstrated by incubation studies [32][33]. Nonetheless, detailed interpretations of the data generated are scarce, especially using a relatively high pyrolysis temperature (700-750 ºC) that is considered more suitable for BC [17,[34][35].…”

Rice straw and chestnut wood were heated between 200 and 1000 °C (T CHAR ) to produce Black C 'thermosequences'. The molecular properties of the charred residues were assessed by pyrolysis-GC/MS to investigate the relation between charring intensity and pyrolysis fingerprint. Samples obtained at T CHAR > 500 ºC (wood) or > 700 ºC (straw) gave low quality pyrograms and poor reproducibility because of high thermal stability, but pyrolysis-GC/MS allowed to track the thermal degradation of the main biocomponents (polysaccharides, lignin, methylene chain-based aliphatics, triterpenoids, chlorophyll and proteins) in the lower temperature range, mostly occurring between T CHAR 250 and 500 ºC. With increasing T CHAR , the charred residues of these biocomponents lose characteristic functional groups, aromatise and finally condense into non-pyrolysable biomass. The proportions of the pyrolysis products of unspecific origin (benzene, toluene, PAHs, etc.), increase with charring intensity, while the ratios that reflect the abundance of alkyl cross-linkages between aromatic moieties (e.g. benzene/toluene, naphthalene/alkylnaphthalene) decrease. These results provide the guidelines to using pyrolysis-GC/MS for the molecular characterisation of different components in Black C and biochar, which is an important parameter for predicting Black C/biochar behaviour in soil. Results are consistent with earlier studies of these samples using the BPCA (benzenepolycarboxylic acid) method and the ring current-induced 13 Cbenzene chemical shift NMR (Nuclear Magnetic Resonance) approach. Pyrolysis-GC/MS provides more information on molecular structures in the low temperature range (T CHAR ≤ 500 ºC) while the BPCA and NMR ring current methods provide more reliable estimations of charring intensity, especially at higher temperatures (T CHAR ≥ 500 ºC).3
