"Liquid-Liquid equilibria for the diesel + comercial tensoactive + glycerin system"
Microemulsified diesel, glycerin, alternative fu
The future lies in energy pluralism. In Brazil, in the case of vehicles, fuels - energy sources – often are ethanol (hydrated ethyl alcohol), gasoline mixed with anhydrous alcohol, diesel oil and natural gas (CNG). The study of new fuels is of great interest, not only for society but also for the industry that over time aims to optimize the efficiency of engines. Environmental agencies increasingly require the use of renewable or less polluting sources of energy, since the emission of gaseous pollutants into the atmosphere (COx, NOx, SOx and soot) has intensified with the increasement of the fleet of fossil fuel vehicles in Brazil and worldwide. This and other factors have served as motivators for research into new formulations, replacing petroleum-derived fuels with some other less polluting ones, such as blends of diesel oil with vegetable oil esters and diesel oil with vegetable oils, emulsions and biofuel micro emulsions generally. Biodiesel in particular appears as a great energy option, as they are renewable, biodegradable sources and the product of their combustion is cleaner than those of petroleum-derived fuels. Glycerin is a sub product of biodiesel production process. Despite the wide industrial use, glycerin is still available, since the market can not absorb the amount that is produced in the biodiesel manufacturing process and this has motivated researchers to develop alternatives for their use, improving their properties and reducing emissions to the atmosphere. In this context, this work deals with the study of the phase equilibrium of the compounds involved in the system (diesel + glycerine solution + surfactants), aiming at a future the energetic use of glycerine for application in internal combustion engines.
