Supported copper oxide catalysts for octanal hydrogenation : the influence of water.
(2010)
Copper oxide supported on alumina (CuO/Al2O3), silica (CuO/SiO2) and chromia
(CuO/Cr2O3) have been synthesized and characterized. These catalysts were
characterized using XRD, SEM, TEM, ICP, BET surface area and pore ...
Studies on the nutritional value of the oils and mesocarp of avocado (Persea americana) and impact of soil quality on elemental composition.
(2011)
This study covered both the Hass and Fuerte varieties of avocado pears. The quality of
extracted avocado oil produced by different extraction techniques was assessed to determine
the effect the extraction method had on ...
Application of cobalt complexes containing SNS ligands as catalysts for biomimetic paraffin activation.
(2012)
A series of SNS ligands have been successfully synthesised and characterised by IR, NMR and
MS. The ligands are divided into two groups and represented by the general formulae: 2,6-
bis(RSCH2)pyridine [R= methyl, ethyl, ...
Synthesis, characterization and application of supported nickel catalysts for the hydrogenation of octanal.
(2010)
Three nickel based catalysts were prepared by the impregnation method (Ni/Al2O3 and Ni/SiO2)
and co-precipitation method (Ni/ZnO). The catalysts were characterized by XRD, ICP-OES,
BET-surface area and pore volume, SEM, ...
Phytochemical and elemental studies of two indigenous medicinal plants of South Africa, Bridelia micrantha and Sideroxylon inerme.
(2014)
Bridelia micrantha (Euphorbaceae) and Sideroxylon inerme (Sapoacaea) are two indigenous medicinal plants found in KwaZulu-Natal and are both known as ‘uMhlalamagwababa’ in isiZulu. These two plants species have similar ...
The oxidative activation of n-octane over titania supported cobalt catalysts.
(2013)
This research effort explored routes to valorise alkanes via heterogeneous catalysis.
Dehydrogenation and oxidative dehydrogenation are the two routes that were probed in this
research effort to activate n-octane by means ...
A comparative study of nickel molybdate and carbon nanotube supported nickel molybdate catalysts for the oxidative dehydrogenation of n-octane.
(2012)
A comparative study of the activation of n-octane over nickel molybdate (α and β-phases), carbon nanotubes and carbon nanotube supported nickel molybdate was carried out in the gas phase in a plug flow fixed bed reactor ...
Application of triazolium-based metal complexes for catalytic oxidation of octane.
(2014)
A series of related 1,2,3-triazole compounds were synthesised and characterised by spectroscopic methods including NMR, IR, MS and X-ray diffraction. N-alkylation of the triazole compounds yielded 1,4-disubstituted triazolium ...
The determination of organochlorinated pesticides and polychlorinated biphenyls in sediment, soil and water of the Msunduzi River, KwaZulu-Natal, South Africa.
(2014)
Persistent organic pollutants (POPs) are a major class of organic contaminants of serious
global concern due to their persistence in the environment because of their stability to
photolytic, chemical and biological ...
The oxidation of n-octane by iridium and cobalt PNP complexes.
(2011)
Paraffin activation has practical implications in the replacement of current
petrochemical feedstocks (olefins), by utilizing economical and easily accessible
alkanes, which may result in more efficient strategies for ...
