Abstract
A first hydroprocessed product and a second hydroprocessed product produced from a multi-stage process for upgrading pyrolysis tar, such as steam cracker tar, are provided herein. Fuel blends including the first hydroprocessed product and/or the second hydroprocessed product are also provided herein as well as methods of lowering pour point of a gas oil using the first hydroprocessed product and the second hydroprocessed product.
Claims21
A first hydroprocessed product comprising:
- aromatics in an amount ≥about 50 wt %;
- paraffins in an amount ≤about 5.0 wt %;
- ≤5 wt. % of the combination of 1.0 ring naphthenes and 2.0 ring naphthenes;
- and
- sulfur in an amount from about 0.10 wt % to <0.50 wt %;
- wherein the first hydroprocessed product has:
- a boiling point distribution of about 145° C. to about 760° C. as measured according to ASTM D6352;
- a pour point of ≤about 0.0° C., as measured according to ASTM D7346;
- and
- a kinematic viscosity at 50° C. from 20 mm2/s to 200 mm2/s, as measured according to ASTM D7042.
A second hydroprocessed product comprising:
- aromatics in an amount ≥about 50 wt %;
- paraffins in an amount ≤about 5.0 wt %;
- ≤5 wt. % of the combination of 1.0 ring naphthenes and 2.0 ring naphthenes;
- and
- sulfur in an amount ≤0.30 wt %;
- wherein the second hydroprocessed product has:
