ABSTRACT:
The invention provides distillate fuel blend components with improved seal swell and lubricity properties obtained from Fischer Tropsch products. The blends contain a highly paraffinic distillate fuel component and distillate-boiling alkylcycloparaffins and/or distillate-boiling alkylaromatics. The invention further provides processes for obtaining such blends using the products of Fischer Tropsch processes. Finally, the invention provides methods for improving seal swell and lubricity properties for distillate fuels.
