|Title of the thesis:||Physical-chemical Properties of Gasoline with Added Alcohols|
|Summary:||Study of the effect of gasoline composition, effect of ethanol and butanol on the resulting physicochemical properties of the fuel mixture was done. Since the ethanol is one of the most used biofuels and with the butanol is being carried out studies for its use in the near future. The present work shows the results of the characterization of commercial mixtures of BOB gasoline with different percentages of ethanol and 1-butanol. The main tests performed on the blends were density and viscosity measured at temperatures -5°C, 5 °C and 15 °C, as well as distillation curves. With the characterization data obtained, it was verified that the density increases, if the amount of alcohol in the mixture increase. Densities grew linearly with the temperature increase for all the mixtures observed. The viscosities of the 1-butanol / gasoline blends compared to the ethanol / gasoline viscosities showed only slightly higher values to a 20% concentration of 1-butanol. Parameters of distillation curve given by standard (E70, E100 and E150) were fulfilled for all ethanol / gasoline mixtures, and only the E70 parameter for 1-butanol / gasoline mixtures with concentration of 1-butanol higher than 15 % did not meet requirements given by E70.|
