Abstract

L'invention concerne un dispositif de réaction (1) qui comprend : un premier corps de transfert de chaleur (7) qui a un premier chemin d'écoulement pour permettre à un premier fluide qui contient une matière première de réaction de s'écouler à travers celui-ci ; un second corps de transfert de chaleur (9) qui est empilé sur le premier corps de transfert de chaleur (7) et qui a un second chemin d'écoulement pour permettre à un second fluide qui est utilisé pour un échange de chaleur avec le premier fluide de s'écouler à travers celui-ci ; une unité de collecte de produit (49) qui a un espace de collecte qui fait face à un orifice d'évacuation (21) en communication avec le premier chemin d'écoulement dans le premier corps de transfert de chaleur (7), et qui collecte un produit qui a été produit dans le premier chemin d'écoulement par réaction endothermique de la matière première de réaction ; et un corps de catalyseur (42) qui est installé dans l'unité de collecte de produit (49) et qui accélère la réaction endothermique de la matière première de réaction qui est restée dans le premier chemin d'écoulement et qui a été évacuée dans l'espace de collecte.
