Fate of sulphate removed during the treatment of circumneutral mine water and acid mine drainage with coal fly ash: Modelling and experimental approach
(Elsevier, 2011)The treatment of acid mine drainage (AMD) and circumneutral mine water (CMW) with South African coal fly ash (FA) provides a low cost and alternative technique for treating mine wastes waters. The sulphate concentration ... -
Carbonation of brine impacted fractionated coal fly ash: Implications for CO2 sequestration
(Elsevier, 2011)Coal combustion by-products such as fly ash (FA), brine and CO2 from coal fired power plants have the potential to impact negatively on the environment. FA and brine can contaminate the soil, surface and ground water through ... -
In-situ ultrasonic monitoring of zeolite A crystallization from coal fly ash
(Elsevier, 2012)In this study, high phase purity of zeolite A was prepared from coal fly ash precursors. The molar regime of both the clear solution extract and unseparated fly ash slurry was adjusted to achieve the right composition for ... -
Novel zeolite Na-X synthesized from fly ash as a heterogeneous catalyst in biodiesel production
(Elsevier, 2012)Several studies have been carried out on the production of biodiesel using different heterogeneous catalysts but this study has been able to demonstrate the prospect of utilizing South African class F fly ash as a raw ... -
Use of coal fly ash as a catalyst in the production of biodiesel
(Slovnaft VÚRUP, 2010)South Africa is largely dependent on the combustion of coal for electricity production; Eskom’s coalfired power stations consume approximately 109 million tons of coal per annum, producing around 25 million tons of ash, ... -
Low-Cost feedstock conversion to biodiesel via ultrasound technology
(MDPI, 2009)Biodiesel has attracted increasing interest and has proved to be a good substitute for fossil-based fuels due to its environmental advantages and availability from renewable resources such as refined and waste vegetable ...
