Mejoramiento de las propiedades de mezclas de gasolina con BIO OIL obtenido por Pirolisis de Polipropileno (PP) y Poliestireno (PS) mediante adición de Nanopartículas de Fe2O3

Abstract

The present study aimed to improve the properties of gasoline blends with bio-oil through the addition of iron oxide nanoparticles (Fe2O3). Three tests were prepared: one of extra gasoline with nanoparticles and two of extra gasoline with bio-oil at 2% and 5% obtained by thermal pyrolysis of polystyrene (PS) and polypropylene (PP) blends with the addition of nanoparticles. We worked with 0.04g/L of catalyst for the three samples, M1 contained 100%, M2 98% and M3 95% of fuelZ; the mixtures were made in hermetically sealed Erlenmeyer flasks to be placed in magnetic stirrers, controlling the revolutions and temperature. At the end of the agitation process, the bio-oil was placed in M2 and M3. The samples were characterized to determine the RON, which presented an octane increase in each sample; the results of density °API, viscosity, flash point and ASTM distillation were within the range of INEN 935 and ASTM D-86. In addition, the behavior of iron oxide nanoparticles (Fe2O3) in the blends was analyzed, where it was determined that the main performance is to reduce the levels of polluting gases, especially NOx. It was concluded that a higher-octane fuel was obtained, with lower gas emissions and excellent calorific value, in addition to giving an added value to the bio-oil that allows reducing gasoline consumption. It is recommended to carry out the mixture in a dispersing medium, adding a stabilizer in the test to avoid the formation of precipitates.
