    摘要： The present invention relates to a method for producing liquid or solid hydrocarbons from a synthesis gas via Fischer-Tropsch synthesis which does not carry out a separate reduction pre-treatment for catalyst activation. The method for producing liquid or solid hydrocarbons from a synthesis gas using Fischer-Tropsch synthesis according to the present invention comprises: a first step of applying an iron-based catalyst for the Fischer-Tropsch synthesis in which the number of iron atoms in the ferrihydrite phase fraction equals 10 to 100% and the number of iron atoms in the hematite phase fraction equals 0 to 90%, with respect to 100% of the number of the number of iron atoms, to a Fischer-Tropsch synthesis reactor; and a second step of activating the catalyst for the Fischer-Tropsch synthesis by a synthesis gas which is a reactant under the conditions of the Fischer-Tropsch synthesis and carrying out the Fischer-Tropsch synthesis by means of the activated catalyst for the Fischer-Tropsch synthesis. As such, the present invention is capable of efficiently producing liquid or solid hydrocarbons from a synthesis gas via Fischer-Tropsch synthesis, even without a separate reduction pre-treatment.

    摘要： This invention relates to a method of preparing an iron carbide/carbon nanocomposite catalyst containing potassium for high temperature Fischer-Tropsch (FT) synthesis reaction and the iron carbide/carbon nanocomposite catalyst prepared thereby, and a method of manufacturing a liquid hydrocarbon using the same and a liquid hydrocarbon manufactured thereby, wherein a porous carbon support is uniformly impregnated with an iron hydrate using melt infiltration, and potassium is also supported together via various addition processes, including a pre-addition process of a potassium salt which is ground upon impregnation with the iron hydrate, or a mid- or post-addition process of a potassium solution using incipient wetness impregnation after impregnation with the iron hydrate. Accordingly, the highly active iron carbide/potassium/carbon composite catalyst for high temperature FT reaction in which 5˜30 wt % of active iron carbide particles are supported on the porous carbon support can be obtained and is structurally stable to heat even in high temperature FT reaction of 300° C. or more, and liquid hydrocarbons can be selectively obtained at high yields.
