In this paper bioethanol/diesel and bioethanol/biodiesel blends,
at several concentrations and temperatures, are studied to find
its possible commercial usage as a fuel to run a diesel power
plant.
The tested fuels were: net mineral diesel fuel (D100) , 5 %
bioethanol/diesel fuel blend (v/v) (E5D95), 10 %
bioethanol/diesel fuel blend (v/v) (E10D90), 15 %
bioethanol/diesel fuel blend (v/v) (E15D85), neat biodiesel
(B100), 5 % bioethanol/biodiesel blend (v/v) (E5B95), 10 %
bioethanol/biodiesel blend (v/v) (E10B90), and 15 %
bioethanol/biodiesel blend (v/v) (E15B85). The fuels were
tested at: 30, 25, 8 and -18 ºC.
This paper shows the observations done in 8 samples during 5
weeks. After each week, each sample was overviewed, and
changes related to stability, colour and aggregation were
recorded.
It has been proved that additives are not necessary to ensure
stability of bioethanol/biodiesel blends under low temperature
conditions, as the phase separation never happens. But in case
of bioethanol/diesel blends some additives are necessary to
keep stability under low temperature conditions.
Based on this study, it can be concluded that blends of biodiesel
fuel with bioethanol up to 15% can be used to fuel a diesel
power plant if engine performance tests corroborate it. The
same conclusion can be applied to blends of diesel fuel with
bioethanol up to 15% blends if additives to keep stability are
added.
