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.

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.

The production of light olefins, as the critical components in chemical industries, is possible via different technologies. The FischerTropsch to olefin (FTO) process aims to convert syngas to light olefins with high selectivity over a proper catalyst, reduce methane formation, and avoid the production of excess CO2. This review describes the production of light olefins through the FTO ...
