  • Musyoka, Nicholas; Petrik, Leslie; Hums, Eric; Baser, Hasan; Schwieger, Wilhelm (Elsevier, 2012)
    In this study, high phase purity of zeolite A was prepared from coal fly ash precursors. The molar regime of both the clear solution extract and unseparated fly ash slurry was adjusted to achieve the right composition for ...
  • 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 ...
  • 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 ...
  • 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 ...
  • Babajide, Omotola; Petrik, Leslie; Musyoka, Nicholas; Amigun, Bamikole; Ameer, Farouk (Slovnaft VÚRUP, 2010)
    South Africa is largely dependent on the combustion of coal for electricity production; Eskom’s coalfired power stations consume approximately 109 million tons of coal per annum, producing around 25 million tons of ash, ...
