|Title:||Composition-Explicit Distillation Curves for Mixtures of Diesel Fuel with Dimethyl Carbonate and Diethyl Carbonate|
|Published:||July 14, 2009|
|Abstract:||We have recently introduced several important improvements in the measurement of distillation curves of complex fluids. The modifications to the classical measurement provide for (1) a composition explicit data channel for each distillate fraction (for both qualitative and quantitative analysis), (2) temperature measurements that are true thermodynamic state points that can be modeled with an equation of state, (3) temperature, volume and pressure measurements of low uncertainty suitable for equation of state development, (4) consistency with a century of historical data, (5) an assessment of the energy content of each distillate fraction, (6) trace chemical analysis of each distillate fraction, (7) corrosivity assessment of each distillate fraction. The composition explicit channel is achieved with a new sampling approach that allows precise qualitative as well as quantitative analyses of each fraction, on the fly. We have applied the new method to the measurement of rocket propellant, gasolines, jet fuels and hydrocarbon crude oils. In this paper we present the application of the technique to representative batches of diesel fuel and mixtures of diesel fuel with two of the more promising oxygenating agents; namely methyl carbonate and ethyl carbonate.|
