    • Biodiesel production from plant oils of African origin 

      Chilabade, D. (North-West University, 2018)
      As the search for alternative sources of energy to supplement traditional fossil-derived energy has intensified across the globe, biodiesel derived from biolipids has emerged as a promising alternative to diesel fuel. This ...

    • Biodiesel production from sunflower oil using microwave assisted transesterification 

      Magida, Nokuthula Ethel (North-West University, 2013)
      Biofuels are becoming more attractive worldwide because of the high energy demands and the fossil fuel resources that are being depleted. Biodiesel is one of the most attractive alternative energy sources to ...

    • Biofuel production from spent coffee grounds via lipase catalysis 

      Karmee, Sanjib Kumar; Swanepoel, Wian; Marx, Sanette (Taylor & Francis, 2018)
      Lipases namely Mucor miehei, Pseudomonas cepacia, Rhizopus delemar, Geotrichum candidum, Candida rugosa, Porcine pancreas-II, Pseudomonas fluorescence, and Candida antarctica lipase-B (Novozyme-435) were employed for ...

    • Biofuels from spent coffee grounds: comparison of processing routes 

      Marx, Sanette; Venter, Roelf; Karmee, Sanjib Kumar; Louw, Jaco; Truter, Chantelle (Taylor & Francis, 2020)
      Bulk fuel was produced from spent coffee grounds (SCG) using different oil extraction and fuel production methods. The highest oil yield (30.2%) and energy efficiency (50%) from continuous hydrothermal liquefaction (CHTL) ...

    • 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 ...

    • Continuous microwave-assisted biodiesel production 

      Nodede, Nomsa Cynthia (North-West University (South Africa) , Potchefstroom Campus, 2016)
      The impetus of this study focuses on the production of fuel-substitute i.e. biofuels. This arises from its similar properties with petroleum diesel and being environmentally benign. In particular, biodiesel is defined as ...

    • The cultivation and harvesting of micro–algal biomass from the Hartbeespoort Dam for the production of biodiesel 

      Brink, Jacobus Petrus (North-West University, 2011)
      Renewable energy sources such as biomass are becoming more and more important as alternative to fossil fuels. One of the most exciting new sources of biomass is micro-algae. The Hartbeespoort Dam, located 37 km west of ...

    • Enzymatic biodiesel production from Manilkara Zapota (L.) seed oil 

      Karmee, Sanjib Kumar (Springer, 2017)
      Oil obtained from the seeds of Manilkara zapota (L.) was transesterified with methanol using lipases as biocatalysts. Four commercially available lipases, such as, porcine pancreas, Candida rugosa, Pseudomonas cepacia and ...
