(EN) COMBINATION OF STRUCTURED CATALYST ELEMENTS AND PELLETS
(FR) COMBINAISON D'ÉLÉMENTS ET DE PASTILLES DE CATALYSEUR STRUCTURÉS
Abstract
(EN)
A steam reformer is provided which comprises at least one externally-heated tube. Each tube comprises a first catalyst bed comprising a first catalyst in particulate form and a second catalyst supported on a structure, wherein said first catalyst bed is located between the inlet of the tube and the second catalyst supported on said structure. A process for steam reforming of a feed gas mixture using said steam reformer is also provided.
(FR)
L'invention concerne un reformeur à vapeur qui comprend au moins un tube chauffé de l'extérieur. Chaque tube comprend un premier lit catalytique comprenant un premier catalyseur sous forme particulaire et un second catalyseur supporté sur une structure, ledit premier lit de catalyseur étant situé entre l'entrée du tube et le second catalyseur supporté sur ladite structure. L'invention concerne également un procédé de reformage à la vapeur d'un mélange gazeux d'alimentation à l'aide dudit reformeur à vapeur.
