Microemulsions from vegetable oil and aqueous alcohol with trialkylamine surfactant as alternative fuel for diesel engines

Patent ·
OSTI ID:6511263
;
Hybrid fuel microemulsions are prepared from vegetable oil, a C/sub 1/-C/sub 3/ alcohol, water, and a surfactant comprising a lower trialkylamine. For enhanced water tolerance by the fuel, the amine is reacted with a longchain fatty acid for conversion to the corresponding trialkylammonium soap. Optionally, 1-butanol is incorporated into the system as a cosurfactant for the purpose of lowering both the viscosity and the solidification temperature.
