A reactor for carrying out a chemical reaction in a three phase slurry system, the reactor comprising: (a) a reaction vessel having a freeboard zone and a slurry zone, the slurry zone having a diameter of at least 0.5 m, preferably greater than 1 m, more preferably greater than 2 m, and a height of at least 15 m preferably at least 10 m; (b) a gas inlet means at or near the bottom of the reaction vessel; (c) a gas outlet at or near the top of the reaction vessel; (d) a plurality of vertical pipes within the reaction vessel slurry zone, therefore pipes having a diameter of from about 1 cm to about 200 cm, and a total perimeter of from about 1400 to about 4000 cm/ra2; and optionally (e) a liquid outlet means. The provision of sufficient vertical pipes in a reaction vessel of this size has been found not only to suppress the tendency of preferred gas flow streams through the liquid and the formation of rolling motions at the slurry, but also to reduce and possibly prevent large scale backmixing of the gas phase, and especially the liquid phase, in the reaction vessel.
