Adsorption behavior of acid-leached clays in bleaching of oil
(Scientific Research Publishing, 2015)The available data have shown that acid-leached clays had sites for adsorption of impurities in oils. Data obtained on residual impurities in cotton and sunflower-seed oils bleached with the same clay materials produced ... -
Designing and Performance Evaluation of Biochar Production in a Top-Lit Updraft Up-scaled Gasifier
(Scientific Research Publishing, 2015)The Original Belonio Rice Husk Gasifier (OBRHG), initially of height of 0.6 m, diameter of 0.15 m and thickness of 0.025 m was tested for biochar production through air gasification of rice husk (RH) and the design was ... -
Distinguishing kaolinites and smectite clays from Central and Eastern Uganda using acidity, pH, colour and composition
(Scientific Research Publishing, 2015)The Langmuir isotherms of 1-aminobutane in isohexane slurries showed increase in clay acidity with increase in concentration of mineral acid used to leach the clay as well as the temperature at which the clay was thermally ... -
The elemental, mineralogical, IR, DTA and XRD analyses characterized clays and clay minerals of Central and Eastern Uganda
(Scientific Research Publishing, 2015)The results on the elemental and mineralogical compositions of clays from Central Uganda differed from those from the volcanic sediments of the Mt. Elgon in Eastern Uganda. Utilisation of the two types of clays should ... -
Spectroscopic analysis of heterogeneous biocatalysts for biodiesel production from expired Sunflower cooking oil
(Hindawi Publishing Company, 2015)The study characterized heterogeneous biocatalyst synthesized from sucrose, saw dust, and chicken egg shells using Fourier Transform Infrared (FTIR) spectroscopy coupled with Attenuated Total Reflectance (ATR) technique. ... -
Sustainable technologies for small-scale biochar production—a review
(Scientific Research Publishing Inc., 2015)Charcoal has found enormous application in both agriculture (AKA biochar) and other sectors. Despite its potential benefits, small scale technologies relevant for its production remain a challenge. Technologies striking a ... -
Upgrading and characterization of smectite from selected volcanic sediments of Eastern Uganda
(2015)Natural clays occur as mixtures of many clay minerals and remains of the rocks that underwent diagenesis to yield the clays. As weathering of clay soils never ceases it may not be possible to mine single clay minerals. The ...
