Blends of Synthetic Distillate and Biodiesel for Low Nitrogen Oxide Emissions from Diesel Engines

摘要

This invention shows how to make and use a biodiesel-based fuel in diesel engines without incurring the NO_x penalty. Embodiments primarily relate to an optimum range of bulk modulus of compressibility for biodiesel blends, which results in generating “NO_x neutral” biodiesel blends or to formulate biodiesel blends with lower NOx emissions than conventional petroleum diesel fuel. These biodiesel blends preferably comprise synthetic paraffinic middle distillate derived from a hydrocarbon synthesis to generate synthetic environmentally-friendly diesel fuels.
