Abstract

The aim of our research work was to prepare stable bioethanol/gas oil emulsions at low temperature (-10°C) in presence of water (1.0-3.0v/v%) by application of different additives, additive compositions and co-solvents (fatty-acid-alkyl-esters, different carbon number bioalcohols). We found that the application of 5v/v% fatty-acid-methyl-ester (FAME) as co-solvent bioethanol/gas oil emulsion containing 6v/v% bioethanol could be produced which was stable at -10°C. With the application of FAME the loss of lubricity caused by the blending of bioethanol could be compensated. With the application of an additive composition prepared from tridecanol- and polyalkyl-succinimid type additives the emulsion was stable in case of water in emulsions. Stability of the emulsions could be increased significantly by blending higher carbon number alcohol (e.g.: biobuthanol) and/or fatty-acid-alkyl-esther (e.g. fatty-acid-butil-esther) as co-solvent.
