초록

The water-gas shift reaction for the compact reformer was carried out at a gas hourly space velocity of 72,152 h-1 over the Cu-Nb-CeO2 catalysts prepared by co-precipitation method. In order to investigate the effect of Nb2O5 promotion over a Cu-CeO2 catalyst, the Nb2O5 loading amount was systematically changed from 0 to 5 wt.%. Among the prepared catalysts, the Cu-Nb-CeO2 (1%) catalyst showed the highest catalytic activity (CO conversion=61% at 400℃) as well as 100% CO2 selectivity. The high activity and stability of Cu-Nb-CeO2 (1%) catalyst are correlated to high Brunauer-Emmett-Teller surface area, small metallic Cu crystallite size, and enhanced redox property.
