- This article concerns assessing the oxidative stability of diesel fuel with FAME and antioxidant additives in dynamic contact with metallic copper. Biodiesel fuel is considered as a better fuel from the environmental point of view compared to petroleum diesel because it is renewable, non-toxic in nature and essentially free of sulphur and aromatics and can be used in any diesel engine without modification. One drawback of biodiesel is that it is susceptible to oxidation which can induce polymerization of esters and can form insoluble gums and sediments which are known to cause fuel filter plugging. Oxidative stability is the basic operational property currently determined for compression-ignition diesel fuels. Excessively low oxidative stability of the fuel is the main reason for not meeting the requirements of PN-EN 590 + A1:2017-06. The European diesel standard EN 590 calls for determining oxidation stability at 110C with a minimum induction time of 20 h according to the Rancimat method (PN-EN 15751). The article presents the research station for assessing the effectiveness of antioxidant additives in fuels treated with copper. The study examined the effect of copper on the oxidative stability of biofuels with various antioxidant additives. The results of the influence of copper on the oxidative stability of biofuels with various antioxidant additives are presented. The dynamic contact of fuel containing bioesters with copper repeatedly accelerates the oxidation process confirming the fact that it has a catalytic effect on oxidative stability. The results of studies on the influence of copper on the oxidative stability of fuels with FAME content above 2% with various antioxidant additives are presented. The relationship between oxidative stability and the type of additive used to prevent excessively rapid oxidation, its concentration and the time of dynamic contact with fuel have been demonstrated. A similar relationship was demonstrated for metal deactivators added to diesel fuel.
