Abstract: The present invention relates to a manufacturing method for an iron-carbide/carbon nanocomposite catalyst containing a potassium additive for high temperature fischer-tropsch synthesis reaction, the iron-carbide/carbon nanocomposite catalyst, a manufacturing method for liquid hydrocarbon using the iron-carbide/carbon nanocomposite catalyst and the liquid hydrocarbon. The purpose of the present invention is to provide the manufacturing method for the iron-carbide/carbon nanocomposite catalyst containing the potassium additive for high temperature fischer-tropsch synthesis reaction which uniformly dips potassium by using various methods such as a prior addition method which uniformly dips heptahydrate salt in an inner portion of a porous carbon support through a melt infiltration method while grinding and putting potassium salt, a middle addition method which infiltrates a potassium solution by a wet dip-coating method after the dip-coating of iron salt and a post addition method, the iron-carbide/carbon nanocomposite catalyst, the manufacturing method for liquid hydrocarbon using the iron-carbide/carbon nanocomposite catalyst and the liquid hydrocarbon. The present invention can produce a highly activated iron-carbide/potassium/carbon-based composite catalyst for a high temperature F-T reaction, wherein 5-30 wt% of activated iron-carbide particles are dipped in the porous carbon support and can manufacture liquid hydrocarbon in a high yield rate since the highly activated iron-carbide/potassium/carbon-based composite catalyst for a high temperature F-T reaction is thermostable in the high temperature F-T reaction of more than 300°C.
