Sumario:Fuel reformulation through the use of oxygenated compounds e.g. dimethyl carbonate (DMC) is a potential option both to reduce the harmful soot emissions and to overcome the dependence on fossil fuels since many of them are bio-derived fuels. DMC presents a relative high oxygen content as compared with other additives and suitable characteristics to be used in combustion systems. The different fundamental aspects of the DMC combustion process including its oxidation behavior its tendency to produce soot and the role of the NO presence in the reaction system were studied. Experiments were conducted under well controlled conditions using specifically designed flow reactor systems. Results demonstrated the low tendency of DMC to form soot compared to other oxygenates and its capacity to contribute to NO reduction under specific fuel-rich conditions. Modeling calculations successfully reproduce reasonably well the experimental trends observed and emphasized the sensitivity of the results to the thermodynamic data of DMC and DMC derived species.
