Low pour point renewable fuel blend

摘要

A renewable fuel blend and a process for producing a renewable fuel blend are described. The blend includes biologically derived C13 to C18 normal paraffins, which are provided to the blend in quantities such that blend does not require a pour point reducing treatment to achieve a low pour point. In embodiments, the normal paraffins are produced in an upgrading process, such as a hydrotreating process.

1. A process for producing a renewable fuel blend comprising:
hydrotreating a biologically derived feedstock selected from animal, vegetable and seed fats and oils, glycerides, lipids, fatty acids, esters of fatty acids, and combinations thereof to form a hydrotreated effluent; recovering biologically derived C14, C16 and C18 normal paraffins from the hydrotreated effluent; blending a petroleum derived middle distillate with 1 vol. % to 20 vol. % of the biologically derived C14, C16 and C18 normal paraffins to produce a renewable fuel blend having a pour point that is in a range from 0° C. to −65° C., the renewable fuel blend further characterized by a ratio ΔC18/(ΔC14+ΔC16) that is less than 0.5, the process not including a pour point reducing treatment, wherein:
ΔC18 represents a quantity of biologically derived C18 normal paraffins, as a vol. % of the renewable fuel blend;ΔC16 represents a quantity of biologically derived C16 normal paraffins, as a vol. % of the renewable fuel blend; andΔC14 represents a quantity of biologically derived C14 normal paraffins, as a vol. % of the renewable fuel blend.
