Abstract
Alternative solutions to the fossil fuel consumption and the concern about environmental pollution and emissions of greenhouse gases indicate the relevance of the biofuels nowadays, such as ethanol and biodiesel. Currently in Brazil, ethanol already appears in the position of a real substitute to gasoline. On the other hand, there is still a long way that biodiesel must go to reach the position of a complete substitute to the mineral diesel. For each liter of biodiesel produced, it is obtained approximately 10% of glycerin, which is a co-product to biodiesel in a transesterification reaction. Furthermore, as in Brazil is mandatory at least 12% of biodiesel blended with diesel, there is an excessive production of glycerin. Based on it, the objective of this work is to ensure the production of biodiesel as much economically viable as possible, introducing the new glycerin/ethanol blend fuel, which is produced by the mixture of ethanol and glycerin (purified commercial product containing 95% or more of glycerol), as to be tested and used in flex-fuel vehicles. Therefore, glycerin could possibly reach the same position as ethanol and biodiesel. First, it was necessary to investigate the homogeneity of glycerin/E100 (hydrous ethanol)/E27 (73% gasoline-27% ethanol) blends. Then, these biofuels were tested in a motorcycle. The mixture of 2% of glycerin with E27 is homogenous and worked correctly in the motorcycle, without noticing any increase in terms of emissions. Glycerin is completely miscible in hydrous ethanol and the mixture of 5% of glycerin on hydrous ethanol worked adequately on the motorcycle tested, without noticing any rise on emissions as well. This research is still in its beginning and work has been done to enable the use of glycerin/ethanol blend according to National Agency of Petroleum, Natural Gas and Biofuels (ANP) resolution Nº 21, in order to obtain prior authorization to test this new approach of experimental biofuel throughout the national territory.
