The results suggested that a dramatic chemical structure change took place during the stages following the plastic layers through to the coke/semi-coke regions. The chemical structure changes were strongly impacted by the properties of the parent coals. The carbon structure changes observed in XPS spectra were in good agreement with the aromatic ring condensation degree, which was indicated by the ratio of out-of-plane aromatic C-H to C=C bonds in aromatic rings. The results showed that the carbon structure evolution took place during the later stages of the thermoplastic ranges, forming the semi-coke.]]> Wed 17 Nov 2021 13:07:30 AEDT ]]> A review of the state-of-the-art research on carbon structure evolution during the coking process: from plastic layer chemistry to 3D carbon structure establishment /manager/Repository/uon:38359 13C NMR) and X-ray photoelectron spectroscopy (XPS), X-ray diffraction (XRD), high-resolution transmission electron microscopy (HRTEM), and Raman spectroscopy. The carbon structure in coke generally is generally in the form of non-graphitic turbostratic structure, which exhibits isotropic property. There is a lack of information in terms of the 3D carbon structure model of coke/semi-coke and how these structures evolve from hydrocarbon sheets to more stable structures above 500 °C in the coke oven. This review also concludes future research scopes and the limitations of current knowledge.]]> Tue 31 Aug 2021 09:15:32 AEST ]]> Using Three-Dimensional Image Analysis Techniques To Understand the Formation of the Plastic Layer during the Heating of Australian Coking Coal Blends /manager/Repository/uon:46699 Tue 29 Nov 2022 09:43:12 AEDT ]]> A comprehensive study on the transformation of chemical structures in the plastic layers during coking of Australian coals /manager/Repository/uon:40832 Tue 19 Jul 2022 10:47:22 AEST ]]>
