Cordierite monoliths, ceramic foams made from mullite and zirconia-alumina as well as gamma-Al2O3 pellets were employed as supports for Ni/La2O3 structured catalysts for the production of hydrogen by catalytic partial oxidation of ethanol. Although all catalysts were very active for ethanol conversion and very selective towards the desired products, the one supported on the zirconia-alumina ceramic foam produced slightly better results. Tested under a wide variety of process conditions, the catalyst supported on the monolith exhibited excellent catalytic performance and long-term stability. In addition to this catalyst, which was prepared by washcoating the active phase on the support, catalysts were prepared on monoliths by adsorption and sot-gel techniques. Adsorption from solutions produced the catalyst with the weakest performance while the sol-gel method resulted in a catalyst with intriguing behavior. Overall, catalysts produced by washcoating on cordierite monoliths are the most promising candidates for the production of hydrogen by partial oxidation of ethanol. Other supports and preparation methods have the potential to produce better catalytic materials but require further optimization. (C) 2003 Elsevier B.V. All rights reserved.
