ABSTRACT:
The present invention relates to a stable, low sulfur, olefinic distillate fuel blend component derived from a Fischer-Tropsch process and a process for producing this stable, low sulfur, olefinic distillate fuel blend component. The stable, low sulfur, olefinic distillate fuel comprises olefins in an amount of 2 to 80 weight percent, non-olefins in an amount of 20 to 98 weight percent wherein the non-olefins are predominantly paraffins, oxygenates in an amount of less than 1 weight percent, and sulfur in an amount of less than 10 ppm by weight. A distillate fuel comprising the above blend component forms less than 5 ppm peroxides after storage at 60° C. for four weeks.
