A slurry bubble column reactor (11) arranged in use to include a slurry phase (12) and above the slurry phase (12), a gas phase (15), the reactor (11) includes a downcomer (16) secured within it. The downcomer (16) comprises an elongate tube, the tube having a lower portion (18) and an upper portion (17). The lower portion (18) has a slurry outlet in the region of the bottom of the tube while the upper portion (17) has a slurry inlet arranged to allow slurry to enter the tube and a gas outlet (21) in the region of the top of the tube. The slurry inlet comprises a series of slots (22) in the wall of the upper portion. The uppermost part of the upper portion (17) extends above the surface of the slurry phase (12) in use and is open for fluid communication with the gas phase (15) above the slurry phase (12), thereby providing the gas outlet (21), and the slots (22) in the upper portion (17) are at a position below the surface of the slurry (12) in use. ® KIPO & WIPO 2007
