Resumen:
Co- and Ce-based structured catalysts deposited on FeCrAlloy monoliths have been prepared.A new two-step strategy for coating the monolith is used: (i) first, a MgAl2O4 spinellayer is generated on the FeCrAlloy substrate, and (ii) then, Co and Ce are incorporated intwo different molar ratios by the conventional wet impregnation method. The spinel layeris formed from a solution of colloidal alumina and Mg(NO3)2, with an apparent viscosity ofaround 3300 mPa s. The results indicate that a homogeneous spinel coating with excellentadherence is obtained after two immersions and a calcination at 700 C. Both structuredcatalysts are active in the steam reforming of ethanol at 650 C. The system with a Co/Cemolar ratio of 3.7 exhibits the best performance with a high stability. A complete ethanol
