  • Biodiesel oxidative stability from Rancimat data 
    Focke, Walter Wilhelm; Van der Westhuizen, Isbe; Oosthuysen, Xander (Elsevier, 2016-06)
    It is conventional to quantify the oxidative stability of oils and biodiesel through an induction time deter-mined by a Rancimat instrument. European Standard EN 14112 for the Rancimat method describes twoprocedures for ...
  • Effect of synthetic antioxidants on the oxidative stability of biodiesel 
    Focke, Walter Wilhelm; Van der Westhuizen, Isbe; Lofte Grobler, A.B.; Nshoane, Khomotso T.; Reddy, Judy K.; Luyt, Adriaan S. (Elsevier, 2012-04)
    Biodiesels were prepared using base catalyzed methanolysis of sunflower, soybean and canola oils. Rancimat oxidative stability measurements showed that the induction period (IP) for neat canola biodiesel conformed to EN ...
  • Stabilizing sunflower biodiesel with synthetic antioxidant blends 
    Van der Westhuizen, Isbe; Focke, Walter Wilhelm (Elsevier, 2018-05)
    Biodiesel was prepared using base catalyzed methanolysis of sunflower oil. The oxidative stability of the neat biodiesel, as well as samples spiked with 0.15 wt% antioxidant was quantified by induction periods (IP) obtained ...
