Abstract

Systems and methods to reduce pour point (PP) temperatures of fat-based compositions for use in transportation fuels. In one or more embodiments, methods and systems reduce the pour point of rendered fats using biologically-derived plant oils for effectively transporting the blended fat based compositions over long distances, thereby advantageously decreasing the heating and mixing requirements needed to maintain the compositional temperature above the pour point. In certain embodiments, the fat based composition comprises rendered animal fats, such as tallow in combination with distilled corn oil (DCO).
