The behaviour of potassium and sodium species during the thermal treatment of a demineralized Highveld coal
(North-West University, 2011)A series of experiments was conducted to investigate the potential influence of pre- and post adding of catalysts to a demineralized coal char. The catalysts were chosen according to yield better catalytic activity and be ... -
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 ... -
The influence of K2CO3 and KCl on H2 formation during heat treatment of an acid-treated inertinite-rich bituminous coal-char
(Springer, 2016)Thermogravimetric-mass spectrometry (TG-MS) studies were conducted in order to investigate the effect of potassium carbonate (K2CO3) and potassium chloride (KCl) on the conversion and hydrogen evolution of chars derived ... -
Methanol quality and its effects on the fuel-cell reformer off-gas composition
(North-West University (South Africa), 2019)Previous research articles that deal with methanol-steam reforming with Cu/ZnO/Al?O? catalyst do not take into account the quality of methanol used and the effect that it would have on catalyst performance and the off-gas ... -
Novel biochemical and catalytic microwave-assisted methods for the synthesis of biobutanol
(North-West University (South-Africa). Potchefstroom Campus, 2019)Biofuels such as bio-ethanol, bio-butanol and biodiesel are attractive fuel substitutes to negate the negative effects of fossil fuel use. Bio-butanol, in particular, is of interest because of its properties, such as; low ... -
Oxidation of sodium thiocyanate (NaSCN) in high ionic-strength process aqueous liquor
(North-West University (South Africa), 2015)The use of liquid redox processes (Stretford Process) for the absorption of H2S from gaseous streams and converting the absorbed H2S into elemental sulphur is widely used. The chemistry of Stretford process aqueous liquors ... -
Synthesis and application of the transition metal complexes of α-pyridinyl alcohols, α-bipyridinyl alcohols, α,α’-pyridinyl diols and α,α’-bipyridinyl diols in homogeneous catalysis
(MDPI, 2018)The paper presents a comprehensive survey on the synthetic procedures of transition metal complexes of α-pyridinyl alcoholato, α-bipyridinyl alcoholato, α,α’-pyridinyl dialcoholato and α,α’-bipyridinyl dialcoholato ligands ...
