  • Reactor for hydrocarbon synthesis
    Patent number: 9687805
    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.
    Type: Grant
