Abstract

The hydrocarbon synthesis reaction apparatus according to the present invention includes a reaction vessel that brings a synthesis gas having carbon monoxide gas and hydrogen gas as main components into contact with a slurry having a solid catalyst suspended in a liquid hydrocarbon compound to synthesize a liquid hydrocarbon compound using a Fischer-Tropsch reaction; a filter that is provided within the reaction vessel and is configured to separate the liquid hydrocarbon compound from the catalyst; and a powdered catalyst particles-discharging device configured to discharge powdered catalyst particles in the solid catalyst in the slurry to the outside of the reaction vessel.
