A tube reactor is based on a laminate that has at least three structure layers (1, 2, 3) and a covering layer (4, 5) on the top and on the underside of the laminate. Each structured layer (1, 2, 3) has many openings (6, 7) which are arranged in one or more longitudinal rows and are elongated, in particular transverse to the longitudinal rows. The openings (6, 6') of a middle layer (1) intersect at least three openings (7, 71) of an adjacent layer (2) or (3), and the sequence of intersecting openings (6, 6'; 7, 7') forms a channel (13) in the longitudinal direction or in the transverse direction of the layers (1; 2). The structured layers (1; 2) are arranged in a periodically recurring fashion. The rows of connected openings (6, 6'; 7, 7') form a channel in the longitudinal direction of the layers (1; 2; 3) which has low backmixing and defines the main directional flow for a fluid flowing through the layers. The openings (6, 6'; 7, 7') may have an elongated geometric shape, in particular be configured as slots, and the longitudinal axis of the main elongation direction of the openings (6, 6'; 7, 7') is at an angle .alpha. to the main direction of flow which is from 5° to 85°, preferably from 30° to 60°.

Réacteur à tubes sur stratifié qui comporte au moins trois couches structurées (1, 2, 3) et une couche de revêtement (4, 5) sur la surface supérieure et inférieure du stratifié. Chaque couche structurée (1, 2, 3) comporte de nombreuses ouvertures (6, 7) disposées en une ou plusieurs rangées longitudinales et allongées, plus précisément de manière transversale par rapport aux rangées longitudinales. Les ouvertures (6, 6') de la couche intermédiaire (1) croisent au moins trois ouvertures (7, 7') d'une couche adjacente (2, 3) et la séquence d'ouvertures qu'elles croisent (6, 6', 7, 7') forme un canal (13) dans le sens longitudinal ou transversal des couches (1, 2). Les couches structurées (1, 2) sont disposées selon un schéma répétitif. Les rangées d'ouvertures liées (6, 6', 7, 7') forment un canal dans le sens longitudinal des couches (1, 2, 3), qui comporte une faible proportion de mélange à contre-courant et établit la principale direction de l'écoulement du liquide dans les couches. Les ouvertures (6, 6', 7, 7') peuvent être de forme géométrique allongée, plus précisément elle peuvent être en fente. L'axe longitudinal du sens de la longueur des ouvertures (6, 6', 7, 7') est dans un angle alpha par rapport à la direction principale de l'écoulement, qui est de 5 à 85 degrés, et de préférence de 30 à 60 degrés.
