TL;DR: The behavior of coal and bibenzyl with respect to anodic oxidation, both in aqueous and in organic media, has been compared in this paper, and complete lack of analogy was observed, suggesting that BIBenzyl could be an oversimplified model.

TL;DR: In this paper, the pyridine-insoluble coal was removed using supercritical CO 2 extraction to maintain the expanded pore structure and showed a loss in macropore surface area and decrease in porosity.
Abstract: Illinois no. 6 coal was swollen and extracted with pyridine to produce pyridine-soluble and pyridine-insoluble fractions. The morphology and liquefaction behaviour of the pyridine-insoluble fraction was affected by the manner in which the residual pyridine was removed. Vacuum drying at 110 o C caused collapse of the pore structure compared to the starting coal. This is evidenced by a loss in macropore surface area (measured with N 2 ) and a decrease in porosity. Using supercritical CO 2 extraction to remove the residual pyridine maintained the expanded pore structure

TL;DR: In this paper, the combustion of coal was studied under non-isothermal conditions in a thermogravimetric analysis apparatus by employing Coats and Redfern kinetic modeling.
Abstract: Kinetics of the combustion of original and depolymerized Assam, Raniganj and Talcher coals and Neyveli lignite has been studied under non-isothermal conditions in a thermogravimetric analysis apparatus by employing Coats and Redfern kinetic modeling. Depolymerization of coals through acidic phenoation was found to improve the reactivity of the coals for combustion. Similarly, depolymerization reaction also led to the improvement in the pyrolysis behavior of coals. The order and activation energy of the reactions have been reported. The kinetics studies of the residual coal obtained after the successive solvent extraction of coal has also been studied. The present studies on the reaction engineering of coal conversion and utilization technologies may help in the reactor design and in the process development engineering.
