Algae liquefaction
(North-West University, 2012)The liquefaction of algae for the recovery of bio–oil was studied. Algae oil is a non–edible feedstock and has minimal impact on food security and food prices; furthermore, it has been identified as a favourable feedstock ... -
Bio-catalytic upgrading of phenolic components present in waste water of a hydrothermal liquefaction plant
(North-West University (South Africa)., 2021)Vanillyl alcohol oxidase is a flavoenzyme naturally sourced from Penicillium simplicissimum. It is a potential candidate in the commercial production of vanillin, an expensive natural flavourant in the cosmetic, food, ... -
Biodiesel production from municipal waste using lipase catalysis
(North-West University (South Africa)., 2022)Municipal solid waste (MSW) and sewage sludge are attractive feedstocks for biofuel production through hydrothermal liquefaction (HTL) due to high moisture content, availability, and low costs. HTL has the advantage of not ... -
Catalytic hydrothermal liquefaction of industrial lignin to bio-oil
(North-West University (South Africa)., 2022)The negative implications of the world’s current fossil fuel systems are driving researchers to search for alternative energy resources. One of the alternative energy resources that has received attention is renewable fuels ... -
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. ... -
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 ... -
Extraction of oil from algae for biofuel production by thermochemical liquefaction
(North-West University, 2009)The extraction of oil from microalgae was investigated. The study focused on the hydrothermal liquefaction of the microalgae Microcystis aeruginosa, Cyclotella meneghinia and Nitzschia pusilla. M. aeruginosa was ... -
In-situ biodiesel production from a municipal waste water clarifier effluent stream
(2014)This study investigated In situ biodiesel production with supercritical methanol. A micro-algae based feedstock was used and obtained from a local water treatment plant situated just outside of Bethal, South Africa (S 26° ...
