Currently, there is a desire to extend or enhance petroleum-derived diesel fuel with biodiesel fuel. Biodiesel fuel is a renewable, biomass-derived fluid that is biodegradable, nontoxic, and a better lubricant compared to petroleum-derived diesel fuels. In this paper, we compare the biodiesel fuel properties from different feedstocks by use of the advanced distillation curve (ADC) method. The feedstocks include a soybean-derived biodiesel fuel, SME, and a cuphea-derived biodiesel fuel, CME. Specifically, we present the thermodynamically consistent distillation curves, and use the composition channel to characterize the curves in terms of composition and available energy content. This work provides a basis of comparison among these fuels in terms of the fundamental thermophysical properties. This comparison will be critical in determining the applicability and suitability of feedstocks designed for the production and manufacturing of biodiesel fuel to enhance or extend current petroleum-derived diesel fuels.
