Evolution of nitrogen functionalities in carbonaceous materials during pyrolysis
TL;DR: In this paper, X-ray photoelectron spectroscopy (XPS) was used to investigate the fate of nitrogen functional forms present in a lignite and its chars, derived from the model compounds acridine, carbazole and polyacrylonitrile (PAN).

A review on surface modification of activated carbon for carbon dioxide adsorption
TL;DR: The influence of surface modification of activated carbon with gaseous ammonia on adsorption properties toward carbon dioxide (CO2) was reviewed in this paper, where two different methods, heat treatment and ammonia treatment (amination) for producing activated carbon had been compared and amination was found to be suitable modification technique for obtaining efficient CO2 adsorbents.

Fuel nitrogen conversion in solid fuel fired systems
TL;DR: In this article, the effect of fuel characteristics, devolatilization conditions and combustion mode on the oxidation selectivity towards NO and N 2 is evaluated and even under idealized conditions, such as a laminar pulverized-fuel flame, the governing mechanisms for fuel nitrogen conversion are not completely understood.

Coal oxidation at low temperatures: oxygen consumption, oxidation products, reaction mechanism and kinetic modelling
TL;DR: In this article, the authors focus on the chemical reactions occurring during low-temperature oxidation of coal and develop a kinetic model to predict the self-heating and gas emission in coal seams.

An introduction to coal technology
TL;DR: In this paper, the origins, formation, and properties of coal are discussed. And the action of solvents on coal is discussed. But they do not discuss the role of coal in coal processing.

Low Temperature Air Oxidation of Caking Coals: Fourier Transform Infrared Studies
TL;DR: Fourier transform infrared spectroscopy has been used to characterize the oxidation of a coking coal and the results demonstrate that the most important initial products of oxidation are carbonyl and carboxylic acid groups.
Journal ArticleDOI
X‐ray photoemission of carbon: Lineshape analysis and application to studies of coals
TL;DR: In this article, the singularity index α of the asymmetric C(1s) x-ray photoelectron spectrum (XPS) of vitreous carbon is determined to be 0.19±0.01, independent of the interlayer separation of the graphitic layers.
Journal ArticleDOI
Oxidation studies on coking coal related to weathering. 4. Oxygen linkages influencing the dilatometric properties and the effect of cleavage of ether linkages
TL;DR: In this article, a vitrinite concentrate of Balmer 10, medium-volatile bituminous coal (433), and highvolatile Moss 3 coal (535) were oxidized in air at 85°C for four days to partially destroy the swelling characteristics as measured by the Ruhr dilatometer.
