Highly paraffinic, moderately aromatic distillate fuel blend stocks prepared by low pressure hydroprocessing of fischer-tropsch products

摘要

The invention relates to a distillate fuel comprising a highly paraffinic, moderately aromatic distillate fuel blend stock (50). The highly paraffinic, moderately aromatic distillate fuel blend stock (50) exhibits excellent combustion properties in diesel and jet engines as a result of the high paraffin content. In addition, the highly paraffinic, moderately aromatic distillate fuel blend stock exhibits improved seal-swell characteristics as a result of the moderate aromatic content. The blend stock (30) is preferably prepared from a Fischer-Tropsch derived product (10) that is hydroprocessed (100) under conditions during which a moderate amount of aromatics are formed.
