Production and high temperature treatment of syngas.
(2010)
Gas cleaning is an essential step in many chemical processes. The reason for cleaning is to remove components that can damage equipment or inhibit further reactions. The treatment can include the removal of particulates, ...
Characterisation and quantification of wood extractives and their impact on pitch.
(2011)
The aims of this study were to characterise and quantify wood extractives in E. grandis and E.
nitens and determine the impact of wood extractives on pitch formation. Initially a comparison
was made with individual solvent ...
Ozone initiated oxidation of organic pollutants, m-xylene and 2-chloroethanol.
(2010)
A variety of hazardous organic compounds are present in leachate from landfill sites that accept medical and industrial chemical waste. Most of these compounds find their way into nearby streams, rivers and dams, posing a ...
Phytochemical and anti-drepanocytosis studies of Cajanus cajan, Callistemon viminalis, Melaleuca bracteata var. Revolution Gold and Syzygium guineense.
(2010)
All over Africa, traditional healers use medicinal plants to prepare medicines to treat a
wide range of illnesses. One of these illnesses is sickle cell anaemia or drepanocytosis
or sicklemia. This disease is particularly ...
Tuning the reactivity of mononuclear tridentate platinum (II) complexes : a detailed kinetic and mechanistic approach using Azole Nucleophiles.
(2014)
The kinetic substitution reactions of two different sets of mononuclear Platinum(II) complexes with heterocyclic bio-relevant azole nucleophiles, viz. Imidazole (Im), 1-methylimidazole (MIm), 1,2-Dimethylimidazole (DIm), ...
The catalysed activation of n-octane over iron modified hydroxyapatites.
(2014)
This research effort investigated the activation of n-octane by oxidative dehydrogenation and
dehydrogenation over iron substituted and iron supported on hydroxyapatite catalysts. Pure
hydroxyapatite and iron substituted ...
The synthesis of xanthene-based transition metal complexes and their application in the oxidation reaction of n-octane.
(2014)
The oxidation of alkanes into valuable products such as alcohols, ketones and aldehydes is very
important to industry for detergents and perfumes. One of the challenges with alkanes is their
inertness which results from ...
Identification and quantification of chelidonic acid and other ligands with potential for Ni uptake in the hyperaccumulator, Berkheya coddii.
(2014)
B. coddii is a known nickel hyperaccumulator, a plant that is able to take up high levels of Ni (< 37 000 mg kg -1) without exhibiting toxic effects. It grows in serpentine soil and is endemic to the Barberton Region, ...
A kinetic and mechanistic study into the substition behaviour of Plantinum (II) Polypyridyl complexes with a series of Azole Ligands.
(2010)
A novel platinum(II) complex, [Pt{4-(o-tolyl)-6-(3˝-isoquinoyl)-2,2´-bipyridine}Cl]SbF6 (Pt4) was synthesized and characterised by means of infrared, elemental analysis, mass spectroscopy, and NMR spectroscopy.
Substitution ...
The preferential oxidation of CO nickel oxide catalysts and the doping effects of platinum in hydrogen rich streams.
(2012)
Hydrogen has now become a suitable candidate for alternative energy generation for small
scale applications with the aid of fuel cells. On-board production of hydrogen from methane
is the most preferred method via a ...
