"Syntroleum Corporation engages in the research, development, and commercialization of the Syntroleum Process that is designed to convert natural gas into synthetic liquid hydrocarbons. It owns the Syntroleum Process for Fischer-Tropsch (FT) conversion of synthesis gas derived from biomass, coal, natural gas, and other carbon-based feedstocks into liquid hydrocarbons; the Synfining Process for upgrading FT liquid hydrocarbons into middle distillate products, such as synthetic diesel and jet fuels; and the Bio-Synfining technology for converting animal fat and vegetable oil feedstocks into middle distillate products, such as renewable diesel and jet fuel."

How it Works

The Syntroleum process produces synthetic fuel by the Fisher-Tropsch process (referred to as FT fuel), which can use natural gas, coal, or biomass as feedstocks. One of the unique features of the Syntroleum process is that it uses air instead of oxygen to produce synthesis gas from natural gas in the gas-to-liquids process.


Syntroleum's Bio-Synfining™ process converts renewable feedstocks, such as fats and vegetable oils, into ultra-clean and environmentally friendly renewable synthetic diesel fuel, renewable synthetic jet fuel, naphtha and propane. Bio-Synfining™ processes triglycerides and/or fatty acids from fats and vegetable oils with heat, hydrogen and proprietary catalysts to make renewable synthetic diesel or jet fuel. Bio-Synfining™ fuels have lower emissions, near zero sulfur, no aromatics, and higher cetane levels than comparable conventional fuels. Bio-Synfining™ fuels can be used at much lower operating temperatures, and can be fully utilized in engines without having to be blended with other fuels. Bio-Synfining™ fuels are expected to be completely compatible with existing pipelines, storage facilities and other conventional fuel infrastructures.

  • Bio-Synfining™ fuels are ultra-clean, flexible in their use, produce fewer emissions and are environmentally friendly.
  • A significant advantage of the Bio-Synfining™ process is that it can produce a middle distillate fuel that can be used in nearly all climates. Bio-Synfining™ can produce summer, winter, and arctic grade renewable diesel as well as renewable jet fuels.
  • Because the Bio-Synfining™ process works at the molecular level, it is flexible enough to produce thermally stable jet fuel by simply adjusting the processing parameters.
  • Syntroleum’s fuels are very low in the three major categories of emissions—nitrogen oxide (NOx), sulfur (almost zero), and aromatics (zero). As a result, its emissions levels are the lowest of any transportation fuel on the market, petroleum based or renewable.
  • They have achieved a 20% increase in Fischer-Tropsch (FT) reactor capacity, a significant increase in wax filtration performance and the development of a new generation attrition-resistant FT catalyst.

Syntroleum has already applied for multiple patents surrounding its Bio-Synfining™ technology, relating to both the process and the synthetic fuels produced. With 160 patents issued and pending, Syntroleum’s renewable fuels, BTL, GTL, and CTL technologies represent the perfect fit to actively pursue synthetic fuels projects.

Abstract A system and process are provided for converting a hydrocarbon gas to a reformed gas containing hydrogen and carbon monoxide. In accordance with a first embodiment, the system includes a primary combustor, compressor and power turbine. The process is practiced by compressing a feed air in the primary compressor to produce a primary air. The primary air is fed with a primary hydrocarbon gas to the primary combustor, producing a reformed gas that drives the primary power turbine. The primary power turbine is linked to the primary compressor, compressing the feed air in an energy self-sufficient manner. In a second embodiment, the system of the first embodiment further includes a secondary combustor, compressor and power turbine. The process is practiced in the same manner as the first embodiment, producing the reformed gas and driving the primary power turbine and compressor. A portion of the primary air is also fed with a secondary hydrocarbon gas to the secondary combustor, producing an off-gas that drives the secondary power turbine and compressor to compress a gas in an energy self-sufficient manner. In a third embodiment, the system is substantially the same as the second embodiment, but reconfigures the compressors and power turbines and further includes an auxiliary secondary power turbine. The process is practiced in the same manner as the first embodiment, producing the reformed gas and driving the primary power turbine and compressor. The off-gas is produced in the same manner as the second embodiment to drive the secondary power turbine, but the secondary power turbine drives an auxiliary primary compressor, compressing the feed air ahead of the primary compressor in an energy self-sufficient manner. The off-gas further drives the auxiliary secondary power turbine to provide additional power for alternate power users.

May 19, 2008 – Dynamic Fuels LLC has secured preliminary approval from the Louisiana State Bond Commission (SBC) of its application to issue tax exempt Gulf Opportunity Zone (GO Zone) Bonds to fund the building of the company’s first renewable synthetic fuels facility in Geismar, Louisiana. Dynamic is a 50:50 venture between Syntroleum Corporation (NASDAQ: SYNM) and Tyson Foods, Inc. (NYSE: TSN) to convert low grade, inedible fats and greases into renewable synthetic diesel, jet and military fuel.
