Co-digestion of sweet sorghum bagasse with scientific and crude glycerols for electricity generation
Fosso-Kankeu, Elvis; Marx, Sanette; Ribberink, Jandri A.; Van den Bergh, Jacobus P.J. (PSRC, 2014)With the global fossil fuel supplies dwindling and the alarming increase of carbon dioxide in the atmosphere, the need for alternative, clean energies, from carbon neutral sources is pressing. This impetus advanced research ... -
Comparative adaptation of B. subtilis and P. aeruginosa in diesel supplemented medium and impact on biodegradation potential
Fosso-Kankeu, Elvis; Marx, Sanette; Brink, Antonie (PSRC, 2014)The degree of diesel blending is likely to influence its toxicity as well as the susceptibility and speed of biodegradation. It is therefore imperative to identify strains that can degrade diesel blend in record time, such ... -
A comparison of biodiesel purification methods
Schabort, C.J.; Van der Walt, P.J.; Marx, S. (ETA-Florence Renewable Energies, 2013)The purification of biodiesel is of cardinal importance to ensure the final product meets industry standards. This final step in the production stage contributes a large portion of the cost attributed to biodiesel production. ... -
Conceptual cost of an integrated micro-algal biomass-to-liquids facility
Brink, Jaco; Marx, Sanette (ETA-Florence Renewable Energies, 2011)An orderofmagnitude cost estimate was conducted on a new integrated biomasstoliquids (BtL) process that produces 2.6 million litres of biodiesel per year from microalgal biomass harvested from the Hartbeespoort Dam. ... -
Conceptual design of an integrated micro-algal biomass-to-liquids process
Brink, Jaco; Marx, Sanette (ETA-Florence Renewable Energies, 2011)A new integrated biomasstoliquids conceptual process was developed to produce 2.6 million litres of biodiesel per year from harvested microalgal biomass. Three unconventional harvesting methods, a thermochemical ... -
Effect of biomass feedstock composition on biochar properties produced through hydrothermal liquefaction
Bartlett, D.; Venter, R.; Marx, S. (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 hydrothermal liquefaction of sugarcane bagasse
Van Rensburg, Gideon; Kruger, Rouxné; Marx, Sanette (EARET, 2018)Hydrothermal liquefaction (HTL) is a thermochemical process that produces various products from lignocellulosic feedstocks. In this study sugar cane bagasse was used as feedstock for HTL. Experiments were carried out ... -
Effect of temperature and cathode material on power production in an earthenware microbial fuel cell
Fosso-Kankeu, Elvis; Rosslee, Gerhard; Pandey, Sadanand; Waanders, Frans; Marx, Sanette (EARET, 2018)This study investigates the performance of microbial fuel cells (MFCs) fed with municipal sewage water considering parameters such as temperature and cathode materials. Single chamber ceramic MFCs with the cathode exposed ... -
Enhancement of bio-methane production by lignocellulose substrates
Mliswa, Vuyo; Marx, Sanette; Chiyanzu, Idan (ETA-Florence Renewable Energies, 2015)In this study, water hyacinth, sweet sorghum bagasse and amaranth stems were used in a pig manure matrix to produce biogas with a high methane content.
