DEVELOPMENT AND TEST OF LIGNOCELLULOSIC BIODERIVATIVES FOR DIESEL ENGINES TO REDUCE EMISSIONS IN THE URBAN ENVIRONMENT
The BIODIET project, supported by the Italian Ministry for Environment, investigates the possibility of using lignocellulosic biomass derived liquids for addition or blending to fossil fuels. The target fuel is diesel oil, i.e. compression ignition engines, thus addressing a different goal than the usual gasoline chain, in which bioethanol is normally blended. The possibility to penetrate the diesel market will open new possibilities for the introduction of sugar-derived liquid biofuels. The project will explore the options offered from the “sugar” chain derived from lignocellulosic biomass fractionation through pretreatment and hydrolysis. Either the direct use of ethanol blended at small amount in diesel oil, or derivatives from the sugar (bio-hydrocarbons) and/or the ethanol (oxygenated additives as acetals, ethers, esters, etc) will be considered. Literature analysis as well as lab scale study will be carried out, to select the most interesting products and processes. The selected option will be considered for engine test in a small bench, where performances and emissions will be monitored. The sustainability of the entire chain will be examined, and a specific LCA conducted on the preferred solution, while results disseminated at the widest possible audience.
