## Abstract

An object is to provide a method for producing a jet fuel composition capable of producing a jet fuel composition with excellent quality at a high yield even when a jet fuel blendstock derived from an FT synthesis oil is used, and a jet fuel composition produced by the production method. It is characterized by including a step of mixing a certain Fischer Tropsch (FT) synthesis jet fuel blendstock with a certain petroleum based jet fuel blendstock so that the ratio of the FT synthesis jet fuel blendstock in the composition ranges from 20 to 80% by volume.

## Claims

### Claim 1

A method for producing a jet fuel composition, including a step of mixing a Fischer Tropsch (FT) synthesis jet fuel blendstock having a density at 15° C. of 0.720 to 0.780 g/cm3, a flash point of 38 to 48° C. and a freezing point of −47 to −43° C. with a petroleum based jet fuel blendstock having a density at 15° C. of 0.770 to 0.850 g/cm3, a flash point of 40 to 48° C., a freezing point of −70 to −50° C. and an aromatic content of 10 to 30% by volume so that the ratio of the FT synthesis jet fuel blendstock in the composition ranges from 20 to 80% by volume.

### Claim 2 (depends on 1)

A method for producing a jet fuel composition according to claim 1, wherein the FT synthesis jet fuel blendstock has a 5% distillation temperature of 160 to 180° C. and a 90% distillation temperature of 210 to 225° C.

### Claim 3 (depends on 1)

A jet fuel composition obtained by the production method according to claim 1, wherein the density at 15° C. is 0.760 to 0.785 g/cm3, the sulfur content is not more than 0.3% by mass, the aromatic content is 5 to 30% by volume, the flash point is 38 to 43° C., and the freezing point is −50 to −45° C.
