Chemical–structural properties of South African bituminous coals: insights from wide angle XRD–carbon fraction analysis, ATR–FTIR, solid state 13C NMR, and HRTEM techniques
(Elsevier, 2015)
The chemical–structural properties of four South African bituminous coals were investigated using wide angle X-ray diffraction–carbon fraction analysis (WAXRD–CFA), attenuated total reflection Fourier transform infra-red ...
Comparing the porosity and surface areas of coal as measured by gas adsorption, mercury intrusion and SAXS techniques
(Elsevier, 2015)
In this paper, we compare the surface area, porosity and other physical–structural properties of four bituminous coals from three different coal fields of South Africa determined using carbon dioxide (CO2) and nitrogen ...
Density functional theory molecular modelling and experimental particle kinetics for CO2-char gasification
(Elsevier, 2015)
Experimental measurements and DFT atomistic modelling were conducted to elucidate the mechanisms for gasification chemistry of char with CO2 gas. The molecular models used were based on experimental representations of coal ...
The characterisation of slow-heated inertinite- and vitrinite-rich coals from the South African coalfields
(Elsevier, 2015)
The development of coal char structures with pyrolysis has been extensively investigated but has traditionally been focused on the carboniferous coals in the northern Hemisphere. In this investigation, the properties of ...
Chemical and structural characterization of char development during lignocellulosic biomass pyrolysis
(Elsevier, 2017)
The chemical and structural changes of three lignocellulosic biomass samples during pyrolysis were investigated using both conventional and advanced characterization techniques. The use of ATR-FTIR as a characterization ...
The carbon dioxide, methane and nitrogen high-pressure sorption properties of South African bituminous coals
(Elsevier, 2019)
In this paper, we report the CO2, CH4 and N2 sorption isotherms of four dry South African bituminous coals at pressures up to 16 MPa at 55 °C. The sorption capacities of the samples with respect to the adsorbate gases ...
X-ray diffraction parameters and reaction rate modeling for gasification and combustion of chars derived from inertinite-rich coals
(Elsevier, 2013)
An investigation was undertaken to determine the effect of carbon structural properties on the reactivity
of chars derived from inertinite-rich coal. The structures of chars were characterized by X-ray diffraction
and ...
Dataset on the carbon dioxide, methane and nitrogen high-pressure sorption properties of South African bituminous coals
(Elsevier, 2019)
The dataset presented in this article supplements the result and information published in the report “The carbon dioxide, methane and nitrogen high-pressure sorption properties of South African bituminous coals” (Okolo et ...
