Journal ArticleDOI
Pore structure characterization of different rank coals using gas adsorption and scanning electron microscopy
TL;DR: In this paper, the pore geometry of coal samples with different metamorphism has been analyzed using low-pressure nitrogen gas adsorption (LP-N2GA) and scanning electron microscopy (SEM).
Journal ArticleDOI
FTIR and Raman spectroscopy characterization of functional groups in various rank coals
TL;DR: In this paper, the chemical and physical properties of coal were investigated using FTIR and Raman spectroscopy, and correlations were established for these parameters, showing that coal structure is complex with three stage characteristics at R o ǫ = 0.4 −1.4−1.3, 1.3 −2.0% and 2.0 −4.0%.
Journal ArticleDOI
Fractal characteristics of coal samples utilizing image analysis and gas adsorption
Xianfeng Liu,Baisheng Nie +1 more
TL;DR: In this paper, the effect of fractal dimensions on methane adsorption capacity was investigated, using scanning electron microscopy (SEM) and low-pressure nitrogen gas adaption (LP-N 2 GA).
Journal ArticleDOI
Nanopore structure of deep-burial coals explored by AFM
TL;DR: In this article, an atomic force microscopy (AFM) measurement was conducted on 12 deep-burial coal samples with different ranks varying from bituminous C to anthracite, attempting to gain clearer insights into the nanopore characteristics and surface roughness.
Journal ArticleDOI
Insight into the macromolecular structural differences between hard coal and deformed soft coal
TL;DR: In this article, Fourier transform infrared (FTIR) spectral and X-ray photoelectron spectrometer (XPS) measurements were conducted on soft and hard coals with metamorphism varying from bituminous coal to anthracite.
