Synthesis of ZSM-5 zeolite from South African fly ash and its application as solid catalyst
(University of the Western cape, 2016)
Zeolites are widely used as environmentally friendly solid catalysts or catalyst supports in the refining and petrochemical industries. ZSM-5 zeolite is composed of a three-dimensional medium pore structure (openings of ...
Determination of toxic elements, rare earth elements and radionuclides in coal fly ash, products and waste
(University of the Western Cape, 2014)
Coal fly ash has been studied extensively to understand the environmental impacts associated with its disposal, management and reuse. Although several beneficiation processes have been proposed, there has been little or ...
Synthesis and characterisation of high silica zeolites with MOR and MFI framework type from South African coal fly ash.
(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 ...
Coal fly ash and acid mine drainage based heterogeneous Fe catalysts Friedel-Crafts alkylation reaction
(University of Western Cape, 2020)
The catalytic support materials used in the present study are zeolite HBEA and MCM-41. These high silica zeolites were synthesised from coal fly ash (CFA) waste via a novel approach that involved a fusion step, acid assisted ...
Sustainable synthesis of BEA zeolite from fly ash-based amorphous silica
(University of Western Cape, 2019)
Power generation in South Africa depends majorly on the combustion of coal and the increasing demand for energy due to industrialisation and population growth signifies the continuous consumption of coal. During this ...
