Behaviour of calcium-containing minerals in the mechanism towards in situ CO2 capture during gasification
(Elsevier, 2008)Mineral matter transformation and the behavior of mineral matter in the coal during gasification, provide more information on the suitability of a specific coal source for combustion or gasification purposes. Therefore, ... -

Determination of mineral matter and elemental composition of individual macerals in coals from Highveld mines
(SAIMM, 2016)A number of conventional and advanced analytical techniques (proximate and ultimate analysis, low-temperature oxygen-plasma ashing, X-ray diffraction, X-ray fluorescence spectrometry, coal petrography, and light-element ... -
The effect of added minerals on the pyrolysis products derived from a vitrinite-rich demineralised South African coal
(Elsevier, 2016)A better understanding of the behaviour of the inorganic matter present in coal will assist in more cost-effective operations and more consistency in product yield and composition during thermal processing. In this study, ... -
Evaluation of mineral matter transformations in low-temperature ashes of South African coal feedstock samples and their density separated cuts using high-temperature X-ray diffraction
(Taylor & Francis, 2020)Coal mineral matter is the leading cause of inevitable ash problems (fouling and slagging) during the combustion of coal. Low-temperature ash (LTA) samples of feed coals and the density separated fractions were subjected ... -
Mineralogical, chemical, and petrographic properties of selected South African power stations’ feed coals and their corresponding density separated fractions using float-sink and reflux classification methods
(Taylor & Francis, 2019)Three South African feed coal samples for the combustion process were beneficiated to produce carbon-rich and mineral-rich fractions. The mineralogical, petrographical, and chemical properties of these feed coals and ...
