    Abstract: A unique process and catalyst is described that operates efficiently for the direct production of a high cetane diesel type fuel or diesel type blending stock from stoichiometric mixtures of hydrogen and carbon monoxide. This invention allows for, but is not limited to, the economical and efficient production high quality diesel type fuels from small or distributed fuel production plants that have an annual production capacity of less than 10,000 barrels of product per day, by eliminating traditional wax upgrading processes. This catalytic process is ideal for distributed diesel fuel production plants such as gas to liquids production and other applications that require optimized economics based on supporting distributed feedstock resources.

  • Patent number: 8748678
    Abstract: A synthetic fuel formula using a blend of High Density Synthetic (HDS) (e.g. Decalin and Tetralin), and Low Density Synthetic (LDS) (e.g. Synthetic Paraffinic Kerosene—SPK) is disclosed. This HDS and LDS blend has been shown to be useful as a jet, rocket and diesel fuel of standard density, and under low temperature conditions. The inventions described herein relate to 100% synthetic hydrocarbon fuels derived from various carbonaceous materials such as, but not limited to, biomass, municipal waste, natural gas, and coal. This 100% synthetic fuel can be universally used for both jet and diesel fuels. It meets Joint Battlefield Use Fuel of the Future (J-BUFF), or Single Battlefield Fuel (SBF) strategic requirements. The commercial advantage of the present invention is that it can be prepared from commercial available fuel stocks or co-processed using currently available chemical processes.
