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 comprising a slurry zone and a freeboard zone, in which slurry zone the catalyst is kept in suspension in a slurry liquid, and in which freeboard zone a liquid reflux is maintained to remove catalyst from the freeboard zone and, preferably, recycling the catalyst to the slurry zone. According to a further aspect, the present invention relates to a three-phase slurry reactor adapted to the process.
