Carbochemistry

TL;DR: Pyridine disrupts the non-covalent crosslinks in coal, so the addition of very small amounts of pyridine leads to an enormous increase in the uptake of chlorobenzene by the coal as discussed by the authors.

TL;DR: In this article, the gasification reaction C CO 2 has been studied using a char produced from an Utrillas lignite (Spain) and the kinetics were investigated under conditions in which the chemical reaction was the controlling step, using 25 MPa total pressure, temperatures between 800 and 1000 °C and a fluidized-bed reactor.

TL;DR: In this article, solid-state CPMAS 13 C NMR and flash pyrolysis-GC-MS were used for characterization of the macromolecular network of a Montana subbituminous coal and its residues from temperature-programmed and nonprogrammed liquefaction (TPL and N-PL) at final temperatures ranging from 300 to 425°C in Hdonor and non-donor solvents.

TL;DR: In this paper, the kinetics of steam gasification was examined for bituminous coals of a low coal rank, which can be the raw material for underground coal gasification.

TL;DR: In this article, the authors investigated the effect of stable carbon-oxygen complex formation on thermogravimetric analysis (TGA) profiles of coal char in oxygen and carbon dioxide and found that the observed differences between reactivity profiles obtained by TGA and those obtained by product gas analysis (e.g. non-dispersive infrared spectroscopy) can be attributed to significant amounts of stable complex being formed during the initial stages of reaction.
