Abstract

The present invention includes a reactor main body ( 4 ) that is formed into a tubular shape having an axis (O) as the center and accumulates a slurry (S); a gas supply line ( 10 ) for incorporating a synthesis gas (G) into the reactor main body ( 4 ), and a sparger part ( 5 ) that is disposed in a lower portion within the reactor main body ( 4 ), communicates with the gas supply line ( 10 ), and sprays the synthesis gas (G). The sparger part ( 5 ) includes a header tube ( 15 ) in which a plurality of openings are formed so as to be separated from each other in a first direction and which sprays the synthesis gas (G) from the openings, and a pair of wall surface parts that protrude from the header tube ( 15 ), on opposing sides of the plurality of openings and in a direction orthogonal to the first direction.
