[Term] Fischer-Tropsch [Explanation] 
Fischer-Tropsch synthesis is a process for producing mainly straight-chain paraffinic hydrocarbons from a synthesis gas having the correct mixture of CO and H2. Catalysts are usually employed. Typical operating conditions for FT synthesis are temperatures of 390-660 °F and pressures of 15-40 atmospheres depending on the desired products. The product range includes the light hydrocarbons methane (CH4) and ethane (C2), LPG (C3-C4), gasoline (C5-C12), diesel (C13-C22), and waxes (>C23). The distribution of the products depends on the catalyst and the process conditions (temperature, pressure, and residence time). The synthesis gas should have low tar and particulate matter content to avoid progressive contamination of the catalysts. Biomass derived synthesis gas for FT liquid production is pre-commercial. However, it may be more easily commercialized than coal since it has smaller quantities of contaminants to remove in the synthesis gas cleaning process.
