Synthesis of zeolites Na-P1 from South African coal fly ash: effect of impeller design and agitation
(MDPI, 2013)
South African fly ash has been shown to be a useful feedstock for the synthesis
of some zeolites. The present study focuses on the effect of impeller design and agitation
rates on the synthesis of zeolite Na-P1 which are ...
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 ...
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 ...
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, ...
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 ...
Statistical testing of input factors in the carbonation of brine impacted fly ash
(Taylor & Francis, 2012)
A D-optimal design was applied in the study of input factors: temperature, pressure, solid/liquid (S/L) ratio and particle size and
their influence on the carbonation of brine impacted fly ash (FA) determined. Both ...
Waste minimization protocols for the process of synthesizing zeolites from South African coal fly ash
(MDPI, 2013)
Production of a high value zeolite from fly ash has been shown to be an avenue
for the utilization of South African fly ash which presently constitutes a huge disposal
problem. The synthesis of zeolites Na-P1 and analcime ...
