Abstract: The present invention relates to a method for manufacturing an iron-carbide/silica nanocomposite catalyst for Fischer-Tropsch synthesis, to a catalyst thereof, to a method for synthesizing liquid hydrocarbon using the same, and to liquid hydrocarbon thereof. Provided are an iron-carbide/silica catalyst for Fischer-Tropsch synthesis, in which an iron-silicate structure having large specific surface area and having well developed pores is first formed by a hydrothermal reaction of silica particles with a nanostructure and an iron salt, and the same is activated in the presence of high temperature carbon monoxide to have high reactivity for Fischer-Tropsch synthesis, and a method for manufacturing the same. And provided are a method for effectively manufacturing liquid hydrocarbon based on high CO conversion ratio and selectivity by Fischer-Tropsch synthesis using the manufactured iron-carbide/silica composite catalyst, and liquid hydrocarbon thereof.
