coal utilization: The FischerTropsch process. FischerTropsch reaction, conversion of socalled synthesis gas, composed mainly of carbon monoxide and hydrogen, to hydrocarbons through the influence of elevated temperatures and normal or elevated pressures in the presence of a catalyst of magnetic iron oxide. The process was first used in.

gasification (Figure 1). The widely known FischerTropsch process was first discovered in the 1920s. It has been commercially practiced by 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 plants.

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.
