Ni/CeO2–MgO catalysts supported on stainless steel plates for ethanol steam reforming

Abstract

Ni/CeO2-MgO catalysts on powder form and supported on stainless steel plateswere prepared, characterized and tested towards hydrogen generation via thesteam reforming reaction of ethanol. The structured catalyst were prepared by thedip-coating technique. The coatings obtained over the stainless steel plates werehomogeneous and retained their integrity after the reaction experiences. Thesamples were characterized by SEM, TEM, XRD, ICP-AES and N2 adsorptiondesorptionmeasurements. Catalysts presented very good stability under reactionconditions for 16 h on-stream, without showing a significant variation in the activityor product distribution. The structured catalysts presented similar activities andselectivities respect to those of the powder, whereby the deposition method did notmodify the catalytic properties of the particulate material. The presence of the AISI430 stainless steel substrate also had not a significant influence on theperformance of the deposited material.
