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 said reactor and at least a portion of the liquid fraction and optionally of the solid fraction of said suspension is recirculated, drawn off from close to one extremity of said reactor and reintroduced close to the other extremity of said reactor, with a liquid flow rate U.sub.1 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.

[ What is claimed is:] [1.] A process for operating a slurry bubble column reactor containing an aerated suspension of a solid fraction in the form of solid particles in a liquid fraction, comprising:injecting a gas phase containing reactant(s) as bubbles close to the lower extremity of said reactor

[ What is claimed is:] [1.] A process for operating a slurry bubble column reactor containing an aerated suspension of a solid fraction in the form of solid particles in a liquid fraction, comprising:injecting a gas phase containing reactant(s) as bubbles close to the lower extremity of said reactor,drawing off at least a portion of said suspension which is non-aerated close to the upper extremity of said reactor,recirculating the non-aerated portion of said suspension by reintroducing said non-aerated portion close to the lower extremity of said reactor,wherein the rate of circulation of the suspension U.sub.1 within said reactor is at least equal to the rate of sedimentation U.sub.s of said solid particles.
