Abstract
The present invention relates to a process for carrying out an exothermic reaction in the presence of a solid catalyst in a three-phase slurry reactor which includes a slurry zone and a freeboard zone. In the slurry zone, the catalyst is kept in suspension in a slurry liquid and in the freeboard zone, a liquid reflux is maintained to remove catalyst from the freeboard zone and, preferably, recycling the catalyst to the slurry zone. The present invention also relates to a three-phase slurry reactor adapted to the process.
