Claim:
1. A method of preparing an iron carbide and carbon carbide/carbon nanocomposite catalyst containing potassium for high temperature Fischer-Tropsch synthesis reaction, comprising: mechanically uniformly grinding non-liquid reagents: an iron hydrate powder, a potassium salt powder and a porous carbon support powder, thus forming a mixed powder wherein the carbon support is not in the form of carbon nanotubes; subjecting the mixed powder to melt infiltration at a temperature near a melting point of the iron hydrate in a reaction vessel; drying the mixed powder at room temperature; calcining the dried mixed powder at a high temperature in an activation gas atmosphere selected from CO and a mixture of CO and H adding the calcined iron carbide and carbon nanocomposite catalyst containing potassium to an organic solvent so as to be stabilized via anti-oxidation passivation; and recovering the iron carbide and carbon nanocomposite catalyst containing potassium from the organic solvent using a magnet, and then performing vacuum drying.
