ABSTRACT:
The invention concerns a process for optimal operation of a slurry bubble column containing a suspension of solid particles in a liquid, characterized in that a gas phase containing the reactant(s) required for the production of the desired products is injected in the form of bubbles close to the lower extremity of the reactor and at least a portion of the liquid fraction and optionally of the solid fraction of the suspension is recirculated, drawn off from close to one extremity of the reactor and reintroduced close to the other extremity of the reactor, with a liquid flow rate U.sub.l in the reactor which is at least equal to and preferably greater than the sedimentation rate U.sub.s of the solid particles. The invention also concerns an apparatus for optimal operation of the process. Finally, the invention concerns the use of the process and apparatus in the Fischer-Tropsch synthesis.
