    Babajide, Omotola; Leslie, Petrik; Amigun, Bamikole; Ameer, Farouk (MDPI, 2009)
    Biodiesel has attracted increasing interest and has proved to be a good substitute for fossil-based fuels due to its environmental advantages and availability from renewable resources such as refined and waste vegetable ...
  • Novel zeolite Na-X synthesized from fly ash as a heterogeneous catalyst in biodiesel production 

    Babajide, Omotola; Petrik, Leslie; Musyoka, Nicholas; Ameer, Farouk (Elsevier, 2012)
    Several studies have been carried out on the production of biodiesel using different heterogeneous catalysts but this study has been able to demonstrate the prospect of utilizing South African class F fly ash as a raw ...
  • Statistical testing of input factors in the carbonation of brine impacted fly ash 

    Muriithi, Grace; Gitari, Wilson; Petrik, Leslie (Taylor & Francis, 2012)
    A D-optimal design was applied in the study of input factors: temperature, pressure, solid/liquid (S/L) ratio and particle size and their influence on the carbonation of brine impacted fly ash (FA) determined. Both ...
