Patent ID: 7666294

Claim:
A kerosene fuel composition having a depressed freeze point comprising: a quantity of petroleum derived kerosene fuel having a boiling point of from 130 to 300° C.; and, an amount of greater than 0 vol. % to about 81 vol. % Fischer-Tropsch derived kerosene fuel comprising 90% w or more normal and iso-paraffins in a weight ratio of greater than 1:1 and having a boiling point of from 130 to 300° C.; wherein the amount of the Fischer-Tropsch derived kerosene fuel is effective, even absent a flow improver additive or wax anti-settling agent, to produce the kerosene fuel composition having the depressed freeze point that is lower than both the freeze point of the petroleum derived kerosene fuel and the freeze point of the Fischer-Tropsch derived kerosene fuel.
