The FischerTropsch process (FT) is a collection of chemical reactions that converts a mixture of carbon monoxide and hydrogen, known as syngas, into liquid hydrocarbons. These reactions occur in the presence of metal catalysts, typically at temperatures of 150300 °C (302572 °F) and pressures of one to several tens of atmospheres.

This review deals mainly with the industrial and practical aspects of the FischerTropsch (FT) process. Currently the world's fuel and chemical production is based predominantly on petroleum crude oil. The presently known reserves of methane and of coal exceed that of crude oil by factors of about and 25, respectively.

Fischer−Tropsch synthesis is technically classified into two categories, the hightemperature Fischer−Tropsch (HTFT) and the lowtemperature Fischer−Tropsch (LTFT) processes. The criterion for this classification is the operating temperature of the synthesis, which ranges between 310−340 °C for the HTFT process and 210−260 °C for the LTFT process.
