Green coal development for application in fixed-bed catalytic gasification
(SAIMM, 2018)
A novel ‘green coal’ product formulation has recently been developed and
the utilization concept tested at the North-West University coal research
laboratories. Hydrothermal liquefaction was used to produce bio-oil ...
Coagulation/flocculation potential of polyaluminium chloride and bentonite clay tested in the removal of methyl red and crystal violet
(Springer, 2017)
This study investigated the influence of the physico-chemical properties of methyl red (MR) and crystal violet (CV) on their removal by bentonite clay and polyaluminium chloride (PACl). Different dosages of bentonite clay, ...
In-situ CO2 capture during a UCG process by simulati ng possible CO2 absorption on roof, floor and coal mineral structures
(International Pittsburgh Coal Conference, 2017)
Leaching of rare earth elements from bentonite clay
(The Southern African Institute of Mining and Metallurgy, 2012)
Due to increasing concerns of global rare earth element shortfalls in
the near future, possible alternative sources of rare earth elements
have recently become of economic interest. One such alternative is
decanting ...
An understanding of the porosity of residual coal/char/ash samples from an air-blown packed bed reactor operating on inertinite-rich lump coal
(Elsevier, 2012)
The thermal treatment of coal causes a development of internal porosity of the resultant char due to the
changes in the coal char pores, i.e. the opening of original closed pores, the formation of new pores, and
an ...
Behaviour of selected major elements during fixed-bed gasification of South African bituminous coal
(Elsevier, 2012)
The Sasol–Lurgi Fixed Bed Dry Bottom gasifier (S–L FBDB) treats a feed coal containing c.a. 30% ash
forming minerals, which means that there are complex mineralogical processes occurring simultaneously
with each other, ...
The use of Mössbauer spectroscopy in environmental research
(Springer, 2017)
The impact that mining has on the environment is becoming an ever increasing problem all over the world. South Africa, Brazil and India are main producers of various valuable resources such as for example iron ore, platinum, ...
Improved gold recovery by accelerated gravity separation
(Gecamin Publishers, 2014)
This project was specifically aimed at using increased acceleration separation, as a method to optimize the recovery of gold in an ore body mainly consisting of hematite where the specific gravity of gold is much higher ...
Evaluation of the antibacterial activity of metal impregnated multi-walled carbon nanotubes: impact of domestic wastewater as supporting medium
(Desalination Publications, 2017)
Despite the availability of potential water treatment resources, bacterial infections are still of major
concern, especially in developing countries where large numbers of people do not have ...
Conceptual use of vortex technologies for syngas purification and separation in UCG applications
(SAIMM, 2018)
Syngas from Africary's Theunissen underground coal gasification (UCG) project will be used for power production and synthesis of liquid fuels and commodity chemicals. However, some of the coal components, especially ...
