Comparative analysis of pyrolysate from herbaceous and woody energy crops by Py-GC with atomic emission and mass spectrometric detection

Molecular characterization of the thermally labile fraction of biochar by hydropyrolysis and pyrolysis-GC/MS

“…Therefore, the influence of feedstock type on PAHs concentration is evidenced by results obtained from biochar produced at low temperature. For beech wood and corn digestate biochar, naphthalene was the most abundant PAH, in accordance to previous studies [33,41,42], followed by phenanthrene. While for the pine wood biochar the most abundant PAH was phenanthrene, followed by naphthalene in BW600 and by fluoranthene and pyrene in BW340.…”

Fast pyrolysis product distribution of biopretreated corn stalk by methanogen

“…Compared to other reactors, fluidized bed reactor given the most potential in converting biomass into bio-oil due to rapid devolatilization, high heating rate (Amutio et al, 2013;Chang et al, 2013;Heidari et al, 2014). The bio-oil was not only used as an alternative to petroleum, but included some high-valuable chemicals such as 5-hydroxymethyl furfural (HMF) (Torri et al, 2010), levoglucose (LG) (Dobele et al, 2005), levoglucosenone (LGO) (Shen et al, 2010) and 4-vinyl phenol (4-VP) (Qu et al, 2013). These had been given much attention in last decades.…”

Activated Carbon, Biochar and Charcoal: Linkages and Synergies across Pyrogenic Carbon’s ABCs

“…So-called fast pyrolysis (sometimes called "flash pyrolysis") and intermediate pyrolysis aim at the production of a mainly liquid product within less than 30 s. This is also often carried at lab scale for mechanistic studies and in combination with analytical chemistry (e.g., mass spectrometry) to investigate the pyrolytic behavior of different feedstock during thermochemical conversion [77].…”
