NOVELTY - A renewable fuel blend comprises in the range of from 1 vol.% to 20 vol.% of biologically derived 13-18C normal paraffins, such that the ratio Delta C18/( Delta C14 + Delta C16) is less than 0.5, where Delta C18 represents a quantity of biologically derived C18 normal paraffins, as a vol.% of the renewable fuel blend; Delta C16 represents a quantity of biologically derived C16 normal paraffins, as a vol.% of the renewable fuel blend; and Delta C14 represents a quantity of biologically derived C14 normal paraffins, as a vol.% of the renewable fuel blend.    USE - The renewable fuel blend is useful for efficiently making a renewable transportation fuel.    ADVANTAGE - The blend includes biologically derived 13-18C 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. The normal paraffins are produced in an upgrading process, such as a hydrotreating process.    DETAILED DESCRIPTION - An INDEPENDENT CLAIM is a process for producing a renewable fuel blend comprising: (a) pretreating at least one biologically derived oil to produce a biologically derived feedstock; (b) hydrotreating a blend of the biologically derived feedstock and a middle distillate to produce at least one hydrotreated liquid effluent; and (c) recovering a renewable fuel blend comprising in the range of from 1 vol.% to 20 vol.% of biologically derived 13-18C normal paraffins, such that the ratio Delta C18/( Delta C14 + Delta C16) is less than 0.5, where Delta C18 represents a quantity of biologically derived C18 normal paraffins provided by the biologically derived feedstock, as a vol.% of the renewable fuel blend; Delta C16 represents a quantity of biologically derived C16 normal paraffins provided by the biologically derived feedstock, as a vol.% of the renewable fuel blend; and Delta C14 represents a quantity of biologically derived C14 normal paraffins provided by the biologically derived feedstock, as a vol.% of the renewable fuel blend.
