Chemical, physical and morphological changes in weathered brine slurried coal fly ash
(University of the Western Cape, 2011)Energy production from coal comes with an environmental cost because of the toxic waste produced during coal combustion such as coal ash and brine which are potential water and soil pollutants. Coal ash and brine contain ... -
CO2 sequestration using brine impacted fly fish
(University of the Western Cape, 2009)It was hypothesized that South African FA and brine could sequester CO2 through mineral carbonation. A statistical approach was undertaken to optimize the % CaCO3 formed from FA/brine/CO2 interaction with input parameters ... -
Determination of total organic carbon content using Passey’s ΔLogR method in coals of the Central Kalahari Karoo Basin, Botswana.
(University of the Western Cape, 2016)The Kalahari Karoo Basin is one of several basins in southern Africa filled with Late Carboniferous to Jurassic sediments that are primary targets for Permian aged coal. In order to determine the Coalbed Methane (CBM) ... -
Mineralogy and chemical mobility in a weathered ash dump site, South Africa
(University of the Western Cape, 2010)Coal fly ash generated from coal fired plants poses potential health risks to humans and plants in the environment due to the surface enrichment of the ash with various toxic trace elements during combustion. Only a small ... -
Zeolite A, X and Cancrinite from South African coal fly ash: mechanism of crystallization, routes to rapid synthesis and new morphology
(University of the Western Cape, 2012)In South Africa, almost 90 % of the country’s electricity is generated from coal combustion. This reliance on coal for energy production is projected to continue in the near and medium term due to the increasing demand for ...
