Abstract:

As an environmentally compatible and cost­effective alternative to conventional diesel, biodiesel has markedly increased its share in the fuel market. Inability to predict its deterioration rate and shelf life from quality characteristics of EN14214 standard can lead to performance problems in all types of diesel fuel equipment. The objectives of this study are to determine the oxidative stability of biodiesel samples by the Rancimat method and find some relationship between oxidative stability and shelf life obtained by monitoring acid value and viscosity characteristics during storage under conditions that are similar to those encountered in use (at 40 oC in low light). The oxidative stability of biodiesel made from rapeseed oil was improved by adding the antioxidant Butylated hydroxytoluene. The results show that the shelf life determination from two different parameters gives practically the same results. In our experiments the oxidative stability changes within 5,89 ­12,37 h, but the shelf life (SL) within 1250 ­8200 h. The shelf life is related to the Rancimat induction period by the relationship lg(SL) = 2,54 lg(Rancimat induction period) + 1,125 (R = 0,9992), which can be used for predicting the shelf life.
