Stabilization of Biodiesel Fuel at Elevated Temperature with Hydrogen Donors: Evaluation with the Advanced Distillation Curve Method
Thomas J. Bruno, Arron Wolk, Alexander Naydich
Recently, we have introduced an advanced distillation curve measurement method featuring (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, and (7) corrosivity assessment of each distillate fraction. We have applied the new method to fundamental work with hydrocarbon mixtures and azeotropic mixtures, and also to real fuels. The fuels we have measured include rocket propellants, gasolines, jet fuels, diesel fuels (including oxygenated diesel fuel and biodiesel fuels) and crude oils. In this paper we show that the method can also be used to assess the oxidative stability of sensitive fluids such as biodiesel fuel. We also test three hydrogen donor molecules (1,2,3,4-tetrahydroquinoline (THQ), 1,2,3,4-tetrahydronaphthalene, and trans-decahydronaphthalene) as potential stabilizers for biodiesel fuel with this new method.
