A method for preparing an iron-based catalyst, the method including preparing iron ore particles by grinding iron ore; and impregnating the iron ore particles with a first metal and second metal, wherein the first metal is selected from copper, cobalt, or manganese, or a combination thereof, and the second metal is selected from an alkali metal or alkali earth metal, or a combination thereof.

Method for preparing iron-based catalyst and iron-based catalyst prepared by the same

The present invention relates to a method for preparing liquid or solid hydrocarbons from syngas via the Fischer-Tropsch synthesis in the presence of iron-based catalysts, the iron-based catalysts for the use thereof, and a method for preparing the iron-based catalysts; more specifically, in the Fischer-Tropsch reaction, liquid or solid hydrocarbons may be prepared specifically with superior productivity and selectivity for Chydrocarbons using the iron-based catalysts comprising iron hydroxide, iron oxide, and iron carbide wherein the number of iron atoms contained in the iron hydroxide is 30% or higher, and the number of iron atoms contained in the iron carbide is 50% or lower, relative to 100% of the number of iron atoms contained in the iron-based catalysts.

Iron-based catalyst and method for preparing the same and use thereof

Iron/carbon (Fe/C) nanocomposite catalysts are prepared for Fischer-Tropsch synthesis reaction. A preparation method includes steps of mixing iron hydrate salts and a mesoporous carbon support to form a mixture, infiltrating the iron hydrate salts into the carbon support through melt infiltration of the mixture near a melting point of the iron hydrate salts, forming iron-carbide particles infiltrated into the carbon support through calcination of the iron hydrate salts infiltrated into the carbon support under a first atmosphere, and vacuum-drying the iron-carbide particles after passivation using ethanol. Using such catalysts, liquid hydrocarbons are produced.
