Abstract:
The present invention relates to a system for manufacturing a hydrocarbon compound by using Fischer-Tropsch synthesis. A catalyst reduction reactor of the present invention in the system for manufacturing the hydrocarbon compound by using the Fischer-Tropsch synthesis comprises a mixer into which an iron-based catalyst is charged, a first synthetic gas is injected for reducing the iron-based catalyst, and into which a second synthetic gas is injected so as to be mixed with the reduced iron-based catalyst. As a result, a catalyst is reduced (activated) in a separate reactor and then introduced into the Fischer-Tropsch reactor thereby facilitating introduction of an additional catalyst when manufacturing the hydrocarbon compound using the Fischer-Tropsch synthesis, and reducing the time required for manufacturing.
