Abstract: PURPOSE: An activation method of a catalyst for the Fischer-Tropsch synthesis is provided to be able to prevent the deactivation of the catalyst due to passivation, and to omit an inconvenient process such as wax charging. CONSTITUTION: An activation method of a catalyst for the Fischer-Tropsch synthesis comprises a first step of applying a catalyst for the Fischer-Tropsch synthesis to a Fischer-Tropsch synthesis reactor, in which a part or the whole of the reduced metal in the catalyst for the Fischer-Tropsch synthesis converts into metal carbide by processing the catalyst for the Fischer-Tropsch synthesis in which a part or the whole of metallic oxide is reduced into the metal from the catalyst for the Fischer-Tropsch synthesis including metallic oxide, with gas including carbon monoxide; and a second step of reducing metal carbide into a metal by contacting gas including hydrogen and the catalyst for the Fischer-Tropsch synthesis including the metal carbide in the reactor under the temperature of the Fischer-Tropsch synthesis reaction.

Abstract: PURPOSE: A reactor for producing hydrocarbon from synthetic gas including prefabricated heat exchanging unit and reacting unit is provided to maximize the heat exchange efficiency by attaching a catalyst on a heat exchanging surface of a heat exchanging plate using a wash-coat method. CONSTITUTION: A reactor for producing hydrocarbon from synthetic gas includes a heat exchanging unit(10), a dispersing unit, a cell(20), a fixing groove, and a flange(40). The heat exchanging unit includes plural heat exchanging plates(1) for injecting a heat transfer medium for the heat exchange, and discharging the heat transfer medium. The dispersing unit disperses the heat transfer medium to each heat exchanging plate. The heat exchanging plates are inserted into a reaction space inside the cell for forming a reaction channel. The reaction channel receives a reaction object, and discharges a reaction mixture. The fixing groove fixes the heat exchanging plates. The flange couples the heat exchanging unit and the cell after attaching a catalyst on the heat exchanging plates.
