Abstract
We have formulated a process for oligomerizing an olefin stream to distillate fuel that meets appropriate distillate requirements. We have found that diesel produced by oligomerizing a charge olefin stream with an oligomerization catalyst to produce an oligomerized olefin stream followed by saturation may have a viscosity that exceeds requirements. The process comprises blending jet fuel with diesel fuel to enable the diesel fuel to meet viscosity qualifications.

A process for oligomerizing an olefin stream comprising:
- oligomerizing a charge olefin stream over an oligomerization catalyst to produce an oligomerized stream;
- hydrogenating said oligomerized stream to provide a distillate stream;
- separating said distillate stream into a jet fuel stream and a diesel stream;
- and
- mixing a blend stream of said jet fuel stream with said diesel stream to provide a product diesel stream.
A process for oligomerizing an olefin stream comprising:
- oligomerizing a charge olefin stream over an oligomerization catalyst to produce an oligomerized stream;
- hydrogenating said oligomerized stream to provide a distillate stream;
- separating said distillate stream into a jet fuel stream and a diesel stream;
- and
- mixing a blend stream of said jet fuel stream with said diesel stream to provide a product diesel stream exhibiting a viscosity of about 1.9 to about 4.1 mm2/s at 40ºC.
