Abstract: The present invention provides an iron-carbide/silica composite catalyst that is highly reactive to a Fischer-Tropsch synthesis by firstly forming an iron-silicate structure having large specific surface area and well-developed pores through a hydrothermal reaction of an iron salt with a silica particle having a nanostructure, and then activating the iron-silicate structure in a high temperature carbon monoxide atmosphere. When using the iron-carbide/silica composite catalyst according to the present invention in the Fischer-Tropsch synthesis reaction, it is possible to effectively prepare liquid hydrocarbon with a high CO conversion rate and selectivity.
