    • In-situ ultrasonic monitoring of zeolite A crystallization from coal fly ash 

      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 ...
    • 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 ...
    • Use of coal fly ash as a catalyst in the production of biodiesel 

      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, ...
