Coating method for Ni/MgAl2O4 deposition on metallic foams

Abstract A new method to deposit active washcoats of Ni/MgAl 2 O 4 steam-reforming catalysts over FeCrAlloy foams is reported in this work. The MgAl 2 O 4 powdered support was prepared via a co-precipitation method, and Ni was dry-impregnated on it. The deposition of the catalyst over the foams was performed by dip-coating followed by air-blowing (dip-blowing). The resulting washcoat layers were quite homogeneous and uniform, and well adherent to the metallic support. Prototype catalyst samples, tested at the lab-scale, were found to be active and selective in the steam reforming process.
