Chemical, physical and morphological changes in weathered coal fly ash : a case study of brine impacted wet ash dump
(University of the Western Cape, 2011)
Fly ash is the major waste material produced by power plants in the combustion of
coal to generate electricity. The main constituents of fly ash are Si, Al, Fe and Ca with smaller amount of S, Mn, Na, K, and traces of ...
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 ...
Synthesis and electrochemical characterisation of conducting polyaniline-fly ash matrix composites
(2005)
The aim of this study was to produce useful composite materials from fly ash, a major waste product of coal combustion from power plants. Polyaniline-fly ash (PANI-FA) composites were prepared by in situ polymerisation of ...
