Cation-exchanged zeolites-A prepared from South African fly ash feedstock for CO2 adsorption
(University of the Western Cape, 2015)
In South Africa coal combustion constitutes up to 90 % of the country’s energy need. This coal combustion activity is known to contribute to the amount of about 40 % of the total CO2 atmospheric emissions worldwide that ...
The role of aluminium content in the control of the morphology of fly ash based hierarchical zeolite X
(University of the Western Cape, 2015)
Coal is the main source of electricity in South Africa, the combustion of which produces a large amount of waste (coal fly ash) annually. The large-scale generation of coal fly ash places major strain on landfills and the ...
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 ...
Chemistry and speciation of potentially toxic and radioactive elements during mine water treatment
(University of the Western Cape, 2012)
Mine water poses a serious environmental challenge and contains elements such as Fe, Al, and Mn in potentially toxic concentrations. The major anion in mine water is sulphate. The complexity and diversity of mine water ...
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 ...
Optimisation of biodiesel production via different catalytic and process systems
(University of the Western Cape, 2011)
The production of biodiesel (methyl esters) from vegetable oils represents analternative means of producing liquid fuels from biomass, and one which is growing rapidly in commercial importance and relevance due to increase ...
Re-use of South African fly ash for CO2 capture and brine remediation.
(University of the Western Cape, 2013)
Coal combustion accounts for 95% of electricity generation in South Africa while globally coal combustion for energy generation stands at 42%. It has been predicted that coal utilization for energy generation will continue ...
