Catalysts deposited on structured supports, such as ceramic or metallic monoliths, have several advantages over conventional packed bed reactors: increase of mass and heat transfer, lower pressure drop, larger surface-to-volume ratio and compact reactor design. Structured supports permit to decrease the particle size of the active metals by using low metal content, maintaining high catalytic performance. Therefore, it is possible to obtain nickel supported catalysts with high resistance toward carbon deposition. In the present work, several Ni structured catalysts were prepared using commercial cordierite monoliths with 400 cpsi cell density. The l carrier was deposited by reliable wash coating method whereas nickel was deposited by either wet impregnation or controlled adsorption methods. Catalysts were characterized by XRD, FE-SEM, H2-TPR, BET techniques. The catalytic activity for DRM was evaluated at 1073K during time on stream at different GHSV.

Abstract
Catalysts deposited on structured supports, such as ceramic or metallic monoliths, have several advantages over conventional packed bed reactors: increase of mass and heat transfer, lower pressure drop, larger surface-to-volume ratio and compact reactor design. Structured supports permit to decrease the particle size of the active metals by using low metal content, maintaining high catalytic performance. Therefore, it is possible to obtain nickel supported catalysts with high resistance toward carbon deposition. In the present work, several Ni structured catalysts were prepared using commercial cordierite monoliths with 400 cpsi cell density. The l carrier was deposited by reliable wash coating method whereas nickel was deposited by either wet impregnation or controlled adsorption methods. Catalysts were characterized by XRD, FE-SEM, H2-TPR, BET techniques. The catalytic activity for DRM was evaluated at 1073K during time on stream at different GHSV.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
