Resumo: |
In nature babassu oil can be applied as fuel in diesel engines. However, such practice is limited by its high viscosity and gum formation tendency. Conversely, vegetal oil-based microemulsions often have appropriated combustion and physicochemical properties. In such context, this work aims to evaluate microemulsions from vegetal oil, hydrated alcohol and fusel oil as an alternative fuel. Thus, the babassu chemical properties were determined by several analyses and its miscibility pattern was evaluated by means of phase diagrams. Based on such study, were selected microemulsion with high oil content. Among them, the 60% oil-based ternary system has presented desired characteristics, being evaluated as pure or binary diesel blended fuels. The combustion efficiency, for all samples, was evaluated according to fuel consumption, gaseous exhaust emission. In general, all microemulsified systems has presented low viscosities, being inferior to the initial oil and equivalent to diesel. Furthermore, it was observed a significant reduction of the gaseous releases for B5 microemulsion blend. |
