Synthesis and characterisation of high silica zeolites with MOR and MFI framework type from South African coal fly ash.
Cornelius, Mero-Lee Ursula (University of the Western Cape, 2019)High-silica zeolites are porous, aluminosilicate materials known for high thermal stability; making these materials favourable for application in various industrial processes involving elevated temperatures. The synthesis ... -
Synthesis and characterization of micro- and mesoporous materials for low temperature selective catalytic reduction of nitrogen oxides
Kasongo Wa Kasongo, Jean B. (University of the Western Cape, 2011)In summary, it has been shown during this study that bimetallic Fe and Mn containing catalysts can be prepared by wet impregnation and not by ion exchange because of the competition between two different metals at different ... -
Synthesis, characterization and physicochemical properties of platinum naboparticles on ordered mesoporous carbon
Saban, Waheed (University of the Western Cape, 2011)In this study SBA-15 mesoporous silica template was synthesized and used as a sacrificial template in the preparation of ordered mesoporous carbon material. A chemical vapour deposition (CVD) technique using LPG or ... -
Treatment of brines using commercial zeolites and zeolites synthesized from fly ash derivative
Sonqishe, Thantaswa Millecent (University of the Western Cape, 2008)The objectives of this project was to ameroliate two waste materials, namely Acid Mine Drainage and Fly Ash and recover the solid residues for conversion into an adsorbent to treat brine. The solid residues were then ... -
Treatment of persistent organic pollutants in wastewater with combined advanced oxidation
Badmus, Kassim Olasunkanmi (University of the Western Cape, 2019)Persistent organic pollutants (POPs) are very tenacious wastewater contaminants with negative impact on the ecosystem. The two major sources of POPs are wastewater from textile industries and pharmaceutical industries. ... -
Zeolite A, X and Cancrinite from South African coal fly ash: mechanism of crystallization, routes to rapid synthesis and new morphology
Musyoka, Nicholas Mulei (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 ...
