摘要: Abstract 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 spinel layer generated substrate, (ii) then, Co Ce are incorporated in two different molar ratios by conventional wet impregnation method. The formed from solution of colloidal alumina Mg(NO3)2, with an apparent viscosity around 3300 mPa s. results indicate that homogeneous excellent adherence obtained after immersions calcination at 700 °C. Both active steam reforming ethanol 650 °C. system Co/Ce ratio 3.7 exhibits best performance high stability. complete conversion hydrogen selectivity 95% reaction cycles 36 h each intermediate regeneration.
