IDENTIFYING OF THE COMPOSITIONS OF THE BLENDED FUELS OF THE BUTANOL, GASOLINE, AND WATER STABILIZED AT LOW TEMPERATURES

The work was purposed to identify the compositions the blended fuel of butanol, gasoline, and water forming the stable emulsions at low temperatures. The previous researches reported that the blending of butanol and gasoline generally employed the synthetic surfactants which were expensive and mixed at room temperatures. It is important to analyze the stability of the substances in the wide range of temperature for it alter significantly on the surface of the planet. The references survey revealed that the works of the compositions of the wet butanol and gasoline at low temperatures are yet published. The present work was successful to blend the butanol, gasoline, and water in stable emulsion without using the surfactant and stabilized in the less of room temperature. Compositions of butanol, gasoline (RONs 90), and water emulsified and stabilized at low temperatures without synthetic surfactants were successfully studied. It was found that aqueous butanol and gasoline formed a stable emulsion at low temperatures and discovered the phase was separated if temperature declined. The compositions of pure butanol, gasoline, and water recorded in stable emulsions using butanol 85.00 % ranged from 75.08–79.24 %, 6.77–11.67 %, and 13.25–13.98 %, respectively, blended at temperatures 0.00–29.70 °C. The usage of butanol 99.50 % caused the change of compositions recorded at 0.71–11.34 %, 88.61–99.29 %, and 0.00–0.06 % blended at 0.00–29.00 °C. It was discovered that the increase of butanol percentage of the fuel after the emulsion was stable tended to the emulsion kept one phase. The emulsion fuels found would be applied to the heat-modified engines operating in wide range temperatures which were below room temperature.
