The object of the study is lignite. Analytical testing techniques, such as elemental analysis, 13C nuclear magnetic resonance (13C NMR) spectroscopy, Fourier transform infrared spectroscopy (FTIR), X-ray photoelectron (XPS), and high-resolution transmission electron microscopy (HRTEM), were used to acquire information on structural parameters aromaticity Xianfeng lignite 43.57%, aromatic carbon structure mainly naphthalene anthracene/phenanthrene. aliphatic dominated by cycloalkanes, alkyl side chains, hydrogenated aromatics. Oxygen present in ether oxygen, carboxyl, carbonyl groups. Nitrogen form pyrrole nitrogen quaternary nitrogen. Sulfur thiophene sulfur. According analysis results, molecular model XF was constructed. formula C184H172O39N6S2. 2D converted a 3D using computer simulation software optimized. optimized has remarkable stereoconfiguration, lamellae are irregularly arranged space. rings connected methylene, hypomethylene, methoxy, rings. In addition, simulated NMR spectra good agreement with experimental spectra. This shows rationality chemical model.

The process of gasification is well-known; however, to this day, the applications such facilities, especially off-grid small-scale units for direct electricity and char production, are scarce. In study, an fixed bed downdraft unit studied from gaseous/solid product character perspective. This represents a possible solution emerging call sustainable decentralised energy sources. Softwood chips were utilised in their conversion into synthetic gas (direct supply) solid biochar was observed analysed. results show promising values potential utilisation different outside combustion process, as microbial syngas fermentation, with lower heating value equal 6.31 MJ·m-3. It appears that during steam activation biochar, both high-quality off-gas more than 70%vol. H2 (excluding N2) activated carbon specific surface area 565.87 m2·g-1 can be collected. Further investigations have revealed degradation chemical bonds material morphology changes gasification. microporous structure high make it attractive further development adsorbent sorption cooling devices. Therefore, waste generated within minimised, obtained products will valued favour sustainability remote locations.
