NOVELTY - Method for preparing hydrophobic carbon-coated iron-based catalyst used in a Fischer-Tropsch synthesis reaction involves (i) dispersing inorganic iron salt, organic ligand and carbon material powder in a solvent, (ii) uniformly stirring the above mixed solution to obtain a stable and uniform solution, (iii) putting the above-mentioned stable and uniform solution in a stainless steel autoclave lined with PTFE for hydrothermal reaction, (iv) cooling the system to room temperature after the reaction, filtering, centrifuging, and washing to obtain a black solid composite, (v) purifying the black solid composite to obtain Material Institut Lavoisier (MIL)-101(iron) doped non-precious group (NPG), and (vi) putting MIL-101(iron) doped NPG in a tube furnace, and performing calcination treatment in an inert atmosphere or a carbon-containing atmosphere to obtain the product. USE - The method is useful for preparing hydrophobic carbon-coated iron-based catalyst in Fischer-Tropsch synthesis reaction. ADVANTAGE - The catalyst prevents the water generated in the Fischer-Tropsch synthesis reaction process from entering the inside of the catalyst, inhibits the water gas shift reaction, inhibits the generation of C1 by-products (carbon dioxide and methane), improves the selectivity to target hydrocarbon product, prevents the active phase inside the catalyst from being oxidized, ensures the activity and stability. The method uses simple and easy to obtain raw materials, and is simple, easy to operate, reproducible, economical and suitable for large-scale production.
