Abstract

A jet-range hydrocarbon product includes a mixture of paraffins. The mixture exhibits a freeze point of less than or equal to about −70° C., a 95% distillation point of greater than or equal to about 275° C., and a smooth boiling point curve that is characterized as having no intervals of the boiling point curve having a slope that is steeper than 4° C./mass % as defined by ASTM standard D2887 between mass recovered ranges of about 20% to about 80%. The steepness of the boiling point curve slope is calculated over any 10 mass % increments within the specified mass % ranges.

First claim

What is claimed is:

1. A jet-range hydrocarbon product comprising:
a mixture of paraffins, wherein the mixture exhibits a freeze point of less than or equal to about −70° C., a 95% distillation point of greater than or equal to about 275° C., and a smooth boiling point curve that is characterized as having no intervals of the boiling point curve having a slope that is steeper than 4° C./mass % as defined by ASTM standard D2887 between mass recovered ranges of about 20% to about 80%,
wherein the steepness of the boiling point curve slope is calculated over any 10 mass % increments within the specified mass % ranges; and
wherein the jet-range hydrocarbon product is produced by oligomerization of C4 olefins using an MTT catalyst.

2. The jet-range hydrocarbon product of claim 1 , wherein the smooth boiling point curve is characterized as having no intervals of the boiling point curve steeper than 4° C./mass % as defined by ASTM standard D2887 between mass recovered ranges of about 10% to about 90%.

3. The jet-range hydrocarbon product of claim 1 , wherein the smooth boiling point curve is further characterized as having no intervals shallower than 0.3° C./mass % as defined by ASTM standard D2887 between mass recovered ranges of about 20% to about 80%.

4. The jet-range hydrocarbon product of claim 3 , wherein the smooth boiling point curve is further characterized as having no intervals shallower than 0.2° C./mass % as defined by ASTM standard D2887 between mass recovered ranges of about 20% to about 80%.

5. The jet-range hydrocarbon product of claim 3 , wherein the smooth boiling point curve is characterized as having no intervals shallower than 0.3° C./mass % as defined by ASTM standard D2887 between mass recovered ranges of about 10% to about 90%.

6. The jet-range hydrocarbon product of claim 5 , wherein the smooth boiling point curve is further characterized as having no intervals shallower than 0.2° C./mass % as defined by ASTM standard D2887 between mass recovered ranges of about 20% to about 80%.

7. The jet-range hydrocarbon product of claim 1 , wherein the mixture exhibits a 95% distillation point of greater than or equal to about 285° C.

8. The jet range hydrocarbon product of claim 1 , wherein the mixture exhibits a freeze point of less than or equal to about −75° C.

9. The jet range hydrocarbon product of claim 1 , wherein the smooth boiling point curve is characterized as having no intervals of the boiling point curve steeper than 2.5° C./mass %.

10. The jet range hydrocarbon product of claim 1 , wherein the mixture of paraffins have a 14 C/ 12 C ratio indicative of atmospheric carbon.

11. A jet-range hydrocarbon product comprising:
a mixture of paraffins, wherein the mixture exhibits a freeze point of less than or equal to about −70° C., a 95% distillation point of greater than or equal to about 275° C., and a smooth boiling point curve that is characterized as having no intervals of the boiling point curve having a slope that is steeper than 4° C./mass % and no intervals shallower than 0.3° C./mass % as defined by ASTM standard D2887 between mass recovered ranges of about 10% to about 90%,
wherein the steepness of the boiling point curve slope is calculated over any 10 mass % increments within the specified mass % ranges; and
wherein the jet-range hydrocarbon product is produced by oligomerization of C4 olefins using an MTT catalyst.

12. The jet range hydrocarbon product of claim 11 , wherein the mixture of paraffins have a 14 C/ 12 C ratio indicative of atmospheric carbon.

13. The jet range hydrocarbon product of claim 12 , wherein the mixture exhibits a freeze point of less than or equal to about −75° C.

14. The jet-range hydrocarbon product of claim 13 , wherein the mixture exhibits a 95% distillation point of greater than or equal to about 285° C.
