  • Patent number: 7354462
    Abstract: Embodiments of the present invention are directed toward systems and methods of providing a low-emissions diesel fuel for use in cold climates. Such fuels may be prepared by a Fischer-Tropsch process and include a pour point depressant. Furthermore, the fuel is used in conjunction with a heated fuel delivery system so that low cloud points are not necessary. Fuels prepared according to embodiments of the present invention may be produced in higher yields than otherwise possible because a higher paraffin wax content can be tolerated, thus obviating the need to remove or exclude the wax. These fuels are characterized by a sulfur content less than 1 ppm, a cetane number greater than 60, an aromatics content less than 1 wt %, and a difference between the cloud and pour points that is greater than about 5° C. The present fuel may be prepared by a Fischer-Tropsch synthesis from any number of carbon-containing sources such natural gas, coal, petroleum products, and combinations thereof.
