The FischerTropsch process involves many kinds of reactions, which lead to both wanted and unwanted results. The desirable reactions create chemicals called alkanes. Sometimes the gas methane (natural gas) is produced, which is generally undesirable. Sometimes, different kinds of alcohol are produced in small amounts.

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.

FisherTropsch Process History. The FT process has been named after two German scientists who developed it in the 1920s: Franz Fischer and Hans Tropsch [249]. Shortly thereafter the process was employed by German companies in full scale industrial plants to manufacture synthetic fuels, mainly diesel, from coal for use by the Germans during WWII.
