Adsorption of metal ions from fine coal tailings dump waste water using bio-char
(EARET, 2018)Coal mining operations produce large amounts of tailings which contains heavy metals. Heavy metals such as cadmium (Cd) can cause environmental problems. The adsorption capacities of biochars produced from spent coffee ... -
Assessing the effects of biochar as an ameliorant for biopesticide polluted soils utilising earthworms
(North-West University (South Africa), 2023)Two plant biopesticides, Bidens pilosa L. and Tagetes minuta L., were investigated for possible effects on earthworms and soil enzymatic activity, compared to the conventional pesticide, Fenamiphos. The efficacy of biochar ... -
Chemical and physical characterization of spent coffee ground biochar treated by a wet oxidation method for the production of a coke substitute
(Elsevier, 2020)Coke production relies on the availability, cost and quality of coking coal. Depleting coking coal resources and environmental pressure force the metallurgical industry to search for alternative methods to produce coke. ... -
Chemical and structural characterization of char development during lignocellulosic biomass pyrolysis
(Elsevier, 2017)The chemical and structural changes of three lignocellulosic biomass samples during pyrolysis were investigated using both conventional and advanced characterization techniques. The use of ATR-FTIR as a characterization ... -
Effect of biomass feedstock composition on biochar properties produced through hydrothermal liquefaction
(EARET, 2018)The effect that 6 different biomass feedstocks have on biochar was investigated. The biochar was produced through hydrothermal liquefaction at temperatures of 260˚C and 300˚C. The effect of temperature was also investigated. ... -
Effect of operating parameters on bio-products obtained from the liquefaction of Quinoa lignocellulose materials
(North-West University (South Africa) , Potchefstroom Campus, 2017)An increased reliance on energy production and the consumption thereof is the result of an exponentially growing world population. Current global energy resources rely greatly on coal, natural gas and to a small extent on ... -
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 ... -
Hydrothermal preparation of biochar from spent coffee grounds, and its application for the removal of cadmium from coal tailings leachate
(SAIMM, 2019)Spent coffee grounds were transformed into biochar using a hydrothermal method. Some of the biochar product was pre-treated through surfactant impregnation with sodium dodecyl sulphate (SDS) to enhance its adsorption ... -
Influence of soil water content and soil amendments on trace metal release and seedling growth in serpentine soil
(Springer, 2019)Purpose This study was conducted to evaluate the synergistic effects of organic amendments and soil water status on trace metal release from serpentine soil. Materials and methods Two organic amendments, dendro-biochar ... -
Liquefaction of sunflower husks for biochar production
(2014)Biochar, a carbon-rich and a potential solid biofuel, is produced during the liquefaction of biomass. Biochar can be combusted for heat and power, gasified, activated for adsorption applications, or applied to soils as a ...
