Investigation of a Ni-based steam reforming catalyst developed for the coating of microstructures

A catalyst based on alumina-supported nickel was synthesized in powder and film form. The alumina support was prepared by a suspension (slurry) coating technique. Afterwards, nickel was added by impregnation, using Ni ( NO 3 ) 2 · 6 H 2 O as precursor. Adherent, porous, thick ( 25 μ m ) alumina film...

Description
Summary:A catalyst based on alumina-supported nickel was synthesized in powder and film form. The alumina support was prepared by a suspension (slurry) coating technique. Afterwards, nickel was added by impregnation, using Ni ( NO 3 ) 2 · 6 H 2 O as precursor. Adherent, porous, thick ( 25 μ m ) alumina films were successfully deposited on microstructures. Initial activity tests regarding the steam reforming of iso-octane at a S / C ratio of 2.34 were performed with the catalyst in powder form in a fixed bed reactor. The chosen reaction conditions were intended to attain full hydrocarbon conversion, in order to represent as close as possible the probable operating conditions in a microreactor for on-board hydrogen production.
