Abstract

The low-temperature water-gas shift (WGS) reaction has been carried out at a very high gas hourly space velocity (GHSV) of 36,201h-1 over supported Cu catalysts prepared by an incipient wetness impregnation method. The preparation method was optimized to get a highly active CeO2 supported Cu catalyst for low-temperature WGS. Co-precipitated Cu-CeO2 exhibited excellent catalytic performance as well as 100% CO2 selectivity. The high activity and stability of co-precipitated Cu-CeO2 catalyst is correlated to its easier reducibility, high surface area and the nano-sized CeO2 with CuO species interacting with the support.
