Abstract. Raw FischerTropsch wax (FT wax) produced from the pilot plant (100t/a, Daixian, Shanxi Province) and the demonstration plant (2,000t/a, Jincheng, Shanxi Province) of coalbased synthetic gasoline process was refined by chemical oxidation. The properties of refined FT wax were greatly improved.

In fact, besides multiple gasifier options and configurations, the liquid fuel synthesis component itself can be approached multiple ways: methanoltogasoline or FischerTropsch (FT) synthesis, to name the two most important.
Fischer−Tropsch (FT), a synthetic technology practiced by Sasol, is a prominent alternative route for the production of synthetic fuels and chemicals. Sasol, in South Africa, uses the hightemperature Fischer−Tropsch (HTFT) process with coal as feedstock to produce a range of synthetic fuels, which includes liquid petroleum gas (LPG ...
gasification (Figure 1). The widely known FischerTropsch process was first discovered in the 1920s. It has been commercially practiced by Sasol in several different forms to produce fuels from either coal or natural gas. No commercial scale coaltoliquid (CTL) plants based on FischerTropsch chemistry have been built since the Sasol plants.
Moreover, the potential outtake of FischerTropsch feedstock was evaluated based on process model results. Utilizing the full biogas plants' carbon potential available in Europe, a total of Mt/h of FischerTropsch fuels and Mt/h of FischerTropsch waxes can be produced, covering up to 79% of the global wax demand.
Synthetic fuel or synfuel is a liquid fuel, or sometimes gaseous fuel, obtained from syngas, a mixture of carbon monoxide and hydrogen, in which the syngas was derived from gasification of solid feedstocks such as coal or biomass or by reforming of natural gas . Common ways for refining synthetic fuels include the FischerTropsch conversion ...

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.
