Abstract:
1. A blended diesel fuel comprising: a) a diesel fuel fraction comprising olefins in an amount of 25 to 80 weight %; non-olefins in an amount of 20 to 75 weight %, wherein the non-olefins comprise greater than 50 weight % paraffins; and oxygenates in an amount of at least 0.012 weight %; b) a diesel fuel fraction selected from the group consisting of a hydrotreated Fischer Tropsch derived diesel, a hydrocracked Fischer Tropsch derived diesel, a hydrotreated petroleum derived diesel, and a hydrocracked petroleum derived diesel, and mixtures thereof; and c) an effective amount of at least one sulfur-free antioxidant from the group consisting of phenols, cyclic amines, and combinations thereof; wherein at least a portion of the blended diesel fuel is derived from Fischer Tropsch synthesis products and the blended diesel fuel comprises sulfur in an amount of less than 1 ppm, and has a reflectance as measured by ASTM D6468 of greater than 65% when measured at 150° C. for 90 minutes and a peroxide number of less than 5 ppm after storage at 60° C. for four weeks.
