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.
