Patent

CA 2262599

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 (1) comprising a slung zone (3) and a freeboard zone (5), in which slurry zone (3) the catalyst is kept in suspension in a slurry liquid, and in which freeboard zone (5) a liquid reflux is maintained to remove catalyst from the freeboard zone and, preferably, recycling the catalyst to the slurry zone (3). According to a further aspect, the present invention relates to a three-phase slurry reactor (1) adapted to the process, in particular a three-phase slung reactor (1) wherein the freeboard zone (5) contains means to trap catalyst particles (10).

L'invention concerne un procédé destiné à effecteur une réaction exothermique, en présence d'un catalyseur solide, dans un réacteur à matière en suspension à trois phases (1), comprenant une zone de matière en suspension (3) et une zone franc-bord (5). Dans la zone de matière en suspension (3), le catalyseur est maintenu en suspension dans un liquide en suspension, cependant que dans la zone franc-bord (5), un reflux liquide est maintenu pour éliminer le catalyseur de la zone franc-bord et, de préférence, pour le recyclage du catalyseur vers la zone de matière en suspension (3). Conforméement à un autre aspect, l'invention concerne un réacteur à matière en suspension à trois phases (1), dans lequel la zone franc-bord (5) présente des moyens pour piéger les particules de catalyseur (10).
