Abstract

La présente invention concerne un appareil de catalyse pour tester des catalyseurs par réglage variable de la pression de traitement dans une plage de pressions de 0,01 Millibar à 300 bar. De préférence, le dispositif dispose d'une pluralité d'espaces réactionnels (101, 102,...) qui sont disposés parallèlement et dont les conduites (211, 212,...) côté sortie des espaces réactionnels sont subdivisées en deux groupes de conduites secondaires. Un groupe de conduites principales (411, 412,...) est en liaison fonctionnelle avec une soupape de réglage (61) commune à toutes les conduites principales et avec une conduite de sortie d'air (62), et le deuxième groupe de conduites secondaires (311, 312, 313,...) dotées de soupapes de commutation (321, 322,...) est en liaison fonctionnelle avec une unité d'analyse (34). De préférence, les conduites (201, 202,...) côté sortie des espaces réactionnels sont respectivement équipées d'une conduite distincte pour l'alimentation en fluide de réglage (211, 212,...). Dans un mode de réalisation préféré, les points de liaison des conduites (201, 202,...) côté sortie des espaces réactionnels vers les conduites principales (411, 412,...) concernées et les conduites secondaires (311, 312,...) présentent respectivement un récipient de mélange (301, 302,...).
