“…The detection of a significant amount of dibenzofuran and alkyl benzenes, and to a lesser extent, phenolic esters, in in the extracts of the six PEN9 coals is consistent with the above description. The presence of dibenzofuran was also evidenced by other studies on extracts of subbituminous and bituminous coals (Fabiańska et al, 2013;Romero-Sarmiento et al, 2011). Polyaromatic hydrocarbons in this experiment occur exclusively as naphthalene and phenanthrene derivatives.…”

“…In this study, particular focus has been applied to three aliphatic groups: n-alkanes, n-alcohols and aliphatic esters since these dominate the extractable compounds detected and greatly contribute to degradability of coals. Being a major biomarker group, the presence of n-alkanes in coal organic extracts has been extensively reported (Fabiańska et al, 2013;Furmann et al, 2013a;Gao et al, 2013;Romero-Sarmiento et al, 2011), spanning a wide spectrum of C 13 to C 30 that encompass the range detected in this experiment.…”

“…Occurrence of aromatic compounds in organic extracts of subbituminous coals has also been reported globally (Fabiańska et al, 2013;Furmann et al, 2013a;Furmann et al, 2013b;Gao et al, 2013;Romero-Sarmiento et al, 2011). Liptinite macerals, such as resinite, sporinite and liptodetrinite that originate from materials rich in cyclics and aromatics (eg.…”

The study sets out to characterize the bioavailability of six Surat Basin Walloon coals from different stratigraphic layers in a single borehole to environmental methanogenic consortia. Factors that control bioavailability have also been investigated on grounds of coal petrographic composition and the organic composition of solvent-extractable matter. Finely crushed coal core samples were inoculated with digested sludge culture from domestic wastewater treatment in serum bottles kept anoxically before incubation at mesophilic temperature over 30 days for biomethane production. Degradation of coal compounds was demonstrated via GC-MS characterization of methanol and dichloromethane (DCM) extracts, in combination with aqueous volatile fatty acids and alcohols and TOC (total organic carbon) analysis on fresh and microbially-digested coal samples. The resulting methane yields ranged from 14 to 33 μmol/g, with an average of 21 μmol/g (0.515 m 3 /tonne), comparable to those previously reported for subbituminous coals. Organic solvent-extractable materials that accounted for 3.8 to 12% of coal weight were generally dominated by aliphatic compounds, composed of mainly medium-long-chain n-alkanes, n-alcohols and esters. Aromatics were detected up to three fused rings, and are rich in dibenzofuran, alkyl benzene, diphenyls and alkyl PAH (polymeric aromatic hydrocarbon). The abundance of solvent-extractable matter was found to be positively associated with liptinite content, particularly suberinite, sporinite and liptodetrinite. Preservation of these compounds was thought to rely on vitrinite, such as telinite and collotelinite that are rich in micropores, serving as storage for the hydrocarbons. Environmental factors, such as microbe-carrying groundwater might compromise coal extractability by converting coal hydrocarbons to biogas. Bioavailability of coal was shown to be controlled by three factors: 1) Water solubility-Bioassay eliminated an average 98% of aqueous compounds (based on TOC), which were dominated by volatile fatty acids and alcohols, and to a lesser degree, medium-chain (primarily C 10 to C 20) n-alcohols, esters and aliphatic amine; 2) Solvent extractability-34.5% of solvent-extractable compounds were shown to be biodegraded (based on peak intensity in GC-MS), with methanol extracts being more bioavailable than DCM's; 3) Heterogeneous moieties, particularly aliphatic hydroxyl group, ester bond, ether bond and C-N bond in aliphatic amine-These functional groups present heteroatoms that can lower the activation energy of nearby bonds, making them vulnerable for microbial cleavage. Compound degradation in bioassays was shown to be clearly associated with methane yield, but only a small proportion degraded was converted to methane. Further improvement may be achieved via proper adaptation of the current microbial community.

“…However, among the 16 PAHs, at almost each sampling point, Ch, Flt, BaA, BkF, and Pyr, the PAHs typical of the emissions from hard coal combustion or coking [19][20][21], had the highest concentrations. Additionally, the profile of PM 4 -bound PAHs was similar to the profile of TSP-bound PAHs at each point, and at P3 and P4 in the open air very similar, making common origin of the PM 4 -and the TSPbound PAHs highly probable.…”

“…The average CPI value of 1.9 of the Phase-I coaly shales is greater than the 1.7 average of the Phase-II coals, suggesting a slightly more abundant contribution of vascular plant waxes in the former relative to the latter. High Pr/Ph ratios in the unweathered coaly shales (9.1 in A2-52; Table 1b) can indicate not only inputs of vascular plant waxes, but also an oxic depositional environment (e.g., Fabiańska et al, 2013). The sterane C 27 /(C 27 +C 29 ) ratio is higher in Phase-II coals than in phase II coaly shales, suggesting additional planktonic inputs (Table 1b).…”
