The present invention relates to a process for contacting a hydrocarbon and an oxygen-containing gas with a catalyst bed in a reactor at a space velocity of at least 10,000 h-1, said process being characterised in that a) the reactor has a polygonal internal cross-section at least in the section where the catalyst bed is held, b) the catalyst bed is made up of 2 or more layers of catalyst in the form of tiles of polygonal shape, said tiles having at least 4 sides, c) each layer of catalyst comprises at least 4 tiles which tessellate together to form said layer, and d) the edges where 2 tiles meet in one layer do not align with the edges where 2 tiles meet in an adjacent layer.

La présente invention concerne un procédé de mise en contact d~un hydrocarbure et d~un gaz contenant de l~oxygène avec un lit catalytique dans un réacteur à une vitesse spatiale supérieure ou égale à 10 000 h-1, ledit procédé étant caractérisé en ce que a) le réacteur présente une section transversale interne polygonale au moins dans la partie où est situé le lit catalytique, b) le lit catalytique est constitué de 2 couches de catalyseur ou plus sous forme de tuiles de forme polygonale, lesdites tuiles ayant au moins 4 côtés, c) chaque couche de catalyseur comprend au moins 4 tuiles disposées de manière à former ladite couche, et d) les arêtes au niveau desquelles 2 tuiles se rencontrent dans une couche ne s'alignent pas avec les arêtes au niveau desquelles 2 tuiles se rencontrent dans une couche adjacente.
