CA 2436884

An apparatus (100) including a plurality of modules stacked end-to-end along a common axis and a multi-step process of converting hydrocarbon fuel (F) to a substantially pure hydrogen gas (P) using said apparatus (100). Each module includes a shell having an interior space defining a passeway for the flow of gas from a first end of the shell to a second end of the shell opposite the first end, and a processing core being contained within the interior space for effecting a chemical, thermal, or physical change to a gas stream passing axially through the module. In one embodiment, said plurality of modules including a first module (110) containing a partial oxidation catalyst and steam reforming catalyst, a seond module (120) containing a first heat exchanger (121), a third module (130) containing a desulfurization agent, a fourth module (140) containing an inert material for mixing components of gas stream passing there through, a fifth module (150) containing a water gas shift catalyst bed, a sixth module (160) containing a second heat exchanger (161) and a seventh module (170) containing a carbon monoxide oxidation catalyst bed.

L'invention concerne un appareil (100) comportant une pluralité de modules empilés bout-à-bout sur un axe commun, ainsi qu'un procédé en plusieurs étapes de conversion de combustible hydrocarboné (F) en hydrogène (P) sensiblement pur, faisant intervenir ledit appareil (100). Chaque module comprend une coquille présentant un espace intérieur qui définit un passage pour l'écoulement du gaz entre la première extrémité de la coquille et la seconde extrémité de la coquille opposée à la première extrémité, et un noyau de traitement contenu dans l'espace intérieur pour soumettre un courant gazeux traversant le module à un changement chimique, thermique ou physique. Dans un autre mode de réalisation, ladite pluralité de modules comprend un premier module (110) contenant un catalyseur d'oxydation partielle et un catalyseur de reformage à la vapeur, un deuxième module (120) contenant un premier échangeur de chaleur (121), un troisième module (130) contenant un agent de désulfuration, un quatrième module (140) contenant un matériau inerte pour mélanger les composants du courant gazeux qui le traverse, un cinquième module (150) contenant un lit catalytique de conversion, un sixième module (160) contenant un second échangeur de chaleur (161) et enfin, un septième module (170) contenant un lit catalytique d'oxydation de monoxyde de carbone.
