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 ...
Rare earths’ recovery from phosphogypsum: An overview on direct and indirect leaching techniques
(MDPI, 2021)
The need for rare earth elements (REEs) in high-tech electrical and electronic-based materials is vital. In the global economy, deposits of natural REEs are limited except for countries such as China, which has prompted ...
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 ...
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 ...
Fusion-assisted hydrothermal synthesis and post-synthesis modification of mesoporous hydroxy sodalite zeolite prepared from waste coal fly ash for biodiesel production
(MDPI, 2022)
Increases in biodiesel prices remains a challenge, mainly due to the high cost of conventional oil feedstocks used during biodiesel production and the challenges associated with using
homogeneous catalysts in the process. ...
Hall measurements on carbon nanotube paper modified with electroless deposited platinum
(Springer, 2010)
Carbon nanotube paper, sometimes referred to
as bucky paper, is a random arrangement of carbon nanotubes meshed into a single robust structure, which can be
manipulated with relative ease. Multi-walled carbon
nanotubes ...
Synthesis of hydroxy sodalite from coal fly ash for biodiesel production from waste-derived maggot oil
(MDPI, 2019)
Zeolites are aluminosilicate crystalline materials known for their unique characteristics, and have been prominent for nearly half a century due to their wide and important industrial applications. The production of zeolites, ...
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 ...
