<p>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.</p> |
