Effectivity of phenol during solvent extraction of a South African bituminous coal under mild conditions
(ACS, 2017)
Solvent extraction of a South African bituminous coal was carried out under mild conditions (<400 °C) with a holding time of 20 min and an initial nitrogen (N2) pressure of 6 MPa. Thermal degradation of coal with phenol ...
Thermodynamic properties and adsorption behaviour of hydrogel nanocomposites for cadmium removal from mine effluents
(Elsevier, 2017)
This research paper reports on the utilization of the hydrogel of gelatine (GL) and its hybrid nanocomposite with clinoptilolite for the adsorption of Cd2+ ions from an aqueous solution and multi-metal ions from mine ...
Evaluation of bio-char based products as hydrotreating catalysts for the production of renewable fuel
(2017)
Increasing demand for alternative fuel from fossil fuel exists which has led to the development of new technologies for the production of bio-fuels. One such technology involves the hydrotreatment of vegetable oils such ...
Induction motor efficiency test methods: a comparison of standards
(IEEE, 2017)
Improved efficiency is the task of the hour. Environmental challenges, which include climate change, global warming and greenhouse gas emission have been fuelling the need to increase energy efficiency in electrical rotating ...

Time of flight secondary ion mass spectrometry and high-resolution transmission electron microscopy/energy dispersive spectroscopy: a study of the distribution of hazardous elements in coal ashes
(International Pittsburgh Coal Conference, 2017)
A review of proton exchange membrane water electrolysis on degradation mechanisms and mitigation strategies
(Elsevier, 2017)
Proton exchange membrane water electrolysis (PEMWE) is an advanced and effective solution to the primary energy storage technologies. A better understanding of performance and durability of PEMWE is critical for the engineers ...
Impact of plasma arc reforming deployment on economic performance of a commercial coal to liquids process
(Elsevier, 2017)
Coal remains integral to the supply of energy in many parts of the world despite the associated negative effects on the environment. Plasma arc reforming has the potential of making coal to liquids processes cleaner by ...
Impact on power factor by small scale renewable energy generation
(IEEE, 2017)
Domestic installations traditionally were believed to be resistive in nature and did not affect power factor much, if at all. With increasing affordability of air-conditioners, and replacement of electrical geysers with ...
Evaluation of design and planning parameter impact by energy efficient measures through appliance-based modelling
(IEEE, 2017)
In a rapidly evolving industry as a result of consumer self-generation and a drive to become more energy efficient, it is necessary to understand whether traditional network planning methods are sufficient. Electrical ...
