  • Esterification of acetic acid with methanol : a kinetic study on Amberlyst 15 
    Schwarzer, Renier Bernhard (University of Pretoria, 2007-05-15)
    Reaction rate data at 50oC was generated in a batch reactor over a wide range of initial concentrations in the reaction mixture. In each case the reaction was allowed to reach equilibrium. Equilibrium conversion data clearly ...
  • I-Hexene dimerisation over a solid phosphoric acid catalyst 
    Schwarzer, Renier Bernhard (University of Pretoria, 2012-06-29)
    Solid phosphoric acid is a catalyst used for the upgrading of light olefins into fuels. To delve into the mechanism of olefin dimerisation over the catalyst, the oligomerisation of 1- hexene was investigated over a wide ...
  • Kinetic model for the dimerisation of 1-hexene over a solid phosphoric acid catalyst 
    Schwarzer, Renier Bernhard; Du Toit, Elizabeth Louisa; Nicol, Willie (Elsevier, 2008-05)
    Batch kinetic experiments at 150 °C, 200 °C and 250 °C showed that the reaction can be modeled with a three step sequential reaction scheme. This involves firstly linear isomerisation of 1-hexene followed by skeletal ...
