A catalyst unit is described in the form of a cylinder having a length C and diameter D, which has two or more flutes running along its length, wherein said cylinder has domed ends of lengths A and B, such that (A+B+C)/D is in the range 0.50 to 2.00, and (A+B)/C is in the range 0.40 to 5.00. The catalyst may be used particularly in reactions where hydrogen is a re-actant such as hydroprocessing, hydrogenation, water-gas shift reactions, methanation, hydrocarbon synthesis by the Fischer-Tropsch reaction, methanol synthesis and ammonia synthesis.

Cette invention concerne une unité de catalyseur ayant la forme d'un cylindre de longueur C et de diamètre D et portant deux cannelures ou plus sur toute sa longueur. Ledit cylindre a des extrémités en forme de dômes de longueurs A et B, telles que (A+B+C)/D est dans la plage de 0,50 à 2,00, et (A+B)/C est dans la plage de 0,40 à 5,00. Le catalyseur peut être utilisé, en particulier, dans les réactions où l'hydrogène est un réactif telles que l'hydrotraitement, l'hydrogénation, les réactions de déplacement eau-gaz, la méthanation, la synthèse d'hydrocarbures par la réaction de Fischer-Tropsch, la synthèse du méthanol et la synthèse de l'ammoniac.
