Transformation of nitrogen functional forms and the accompanying chemical-structural properties emanating from pyrolysis of bituminous coals
(Elsevier, 2018)
Characterisation of simultaneous changes in nitrogen functionalities and condensed aromatic crystallites during pyrolysis of bituminous coals was conducted. X-ray photoelectron spectroscopy (XPS) was utilised to determine ...
Exploring the potential of petrographics in understanding coal pyrolysis
(Elsevier, 2015)
The effects of heating manner and charring temperature on both the physical and chemical properties of coal were investigated by petrographic techniques. Six coal samples of different rank were subjected to chemical treatment ...
