Abstract
This application discloses a process for making jet fuel including: (1) oligomerizing an olefin stream to an oligomer stream; (2) hydrogenating said oligomer stream to provide a paraffin stream; (3) separating said paraffin stream to provide a jet fuel stream and a reformer feed stream; and (4) reforming said reformer feed stream to provide a reformed stream with an increased concentration of aromatics.
Claims20
A process for making jet fuel or jet fuel blend stock comprising:
- oligomerizing an olefin stream to an oligomer stream;
- hydrogenating said oligomer stream to provide a paraffin stream;
- separating said paraffin stream to provide a jet fuel stream and a reformer feed stream;
- reforming said reformer feed stream to provide a reformed stream comprising an increased concentration of aromatics.
An apparatus for making jet fuel comprising:
- an oligomerization reactor having a first outlet stream;
- a hydrogenation reactor in communication with the first outlet stream and having a second outlet stream;
- a jet fractionation column in communication with the second outlet stream to separate the second outlet stream into a third outlet stream and a fourth outlet stream;
- and,
- a reformer reactor in communication with the third outlet stream to produce a fifth outlet stream with an increased aromatics content.
An apparatus for making jet fuel comprising:
- an oligomerization reactor having a first stage for forming a first oligomer stream and a second stage in communication with the first oligomer stream to form a second oligomer stream;
- a hydrogenation reactor in communication with the second oligomer stream and having a hydrogenated hydrocarbon outlet stream;
- a fractionation column in communication with the hydrogenated hydrocarbon outlet stream to separate the hydrocarbon outlet stream into a jet fuel outlet stream and a reformer outlet stream;
- and,
- a reformer reactor in communication with the reformer outlet stream to produce a jet fuel stream with an increased aromatics content.
