The application of bioethanol/diesel fuel emulsions is constrained by several factors (e.g. hydrocarbon composition of base gas oil, temperature, concentration and water content of bioethanol, presence of co-solvent, quality and quantity of the applied additive). The focus of our development work was to study the effect of a new chemical structure additive (fatty-acid-methyl-ester containing polyisobutylene-succinic derived) and co-solvent (fatty-acid-alkyl-esters and different carbon number alcohols) on the stability of bioethanol/gas oil emulsion, and to produce stable emulsions even in case of low temperature (-20°C) and presence of water (5.0% water containing bioethanol). It was found that high stability bioethanol/gas oil emulsion could be produced with 5.0 v/v% biodiesel as co-solvent in base gas oil and 4.0% new chemical structure additive, which was stable at the temperature of -20°C and in the presence of 5.0 v/v% water containing bioethanol.
