The invention concerns a reactor (R) for chemical conversion in the presence of a gas diluent comprising between an upper end and a lower end a substantially vertical catalytic bed (3a, 3b, 3c) and comprising in combination proximate to its upper end at least means (9) for introducing a solid catalyst, means for introducing (1) and evacuating (2) said feedstock enabling its substantially horizontal circulation across the catalytic bed (3a, 3b, 3c), proximate to its lower end catalyst extracting means (7a, 7b, 7c, 8a, 8b, 8c), at least means for heating (4a, 4b) said feedstock to which said diluent has been added, said means (4a, 4b) being internal to the reactor (R) and traversed by said diluent-added feedstock in the absence of the catalyst, and separating the catalytic bed (3a, 3b, 3c) into an upstream part and a downstream part at said heating means (4a, 4b) relative to the feedstock circulating direction, comprising at least means for introducing a stream of said gas diluent (10a, 10b, 10c) substantially proximate to at least one of the upper and/or lower ends of said upstream part of the catalytic bed (3a, 3b), so as to at least reduce bypassing of said heating means by said diluent-added feedstock.
Réacteur (R) de conversion chimique en présence d'un diluant gazeaux contenant entre une extrémité supérieure et une extrémité inférieure un lit catalytique (3a, 3b, 3c) sensiblement vertical et comportant en combinaison à proximité de son extrémité supérieure au moins un moyen (9) d'introduction d'un catalyseur solide, des moyens d'introduction (1) et d'évacuation (2) de ladite charge permettant sa circulation de façon sensiblement horizontale à travers le lit catalytique (3a, 3b,3c), à proximité de son extrémité inférieure au moins un moyen d'extraction de catalyseur (7a, 7b, 7b, 8a, 8b, 8c), au moins un moyen de chauffage (4a, 4b) de ladit
