摘要：
Novel Cu-based catalysts supported on both Ce-La-Al and Ce-Zr-Al supports were investigated for the water-gas shift reaction in the temperature range 450 to 600 C Ce-La-Al containing Cu catalysts exhibited high activity and stability for the high temperature water-gas shift reaction with catalyst 10%Cu/(36 8% CeO2 + 30 2%LaOx + 33 0%AlOx) (CE18) achieving the highest activity with 15 5% CO conversion at 600 C and atmospheric pressure higher than its counterpart Ce-Zr-Al containing Cu catalyst This high activity and stability may originate from the synergistic effect of the interaction between Cu and catalyst support the redox behaviour of catalyst support as well as the stabilizing effect of Al2O3 Crown Copyright (C) 2010 Published by Elsevier B V All rights reserved
