Abstract
The present study focuses on the use of spinel ferrite (MFe2O4) catalysts (M=Ni, Co, Fe, or Cu) integrated with mesoporous alumina for the high temperature water-gas shift (WGS) reaction. Among these catalysts, copper ferrite integrated with mesoporous alumina exhibits outstanding performance. To optimize the Cu/Fe ratio in the copper ferrite catalyst, we prepared different CuxFe(3-x)O4-MA catalysts (x=0.5, 1.0, 1.5, 2.0, or 2.5) by varying the Cu/Fe mole ratio. Of the various Cu/Fe catalysts, the 1:1 mole ratio of Cu/Fe exhibited the highest CO conversion (84%) and 100% selectivity to CO2 at a very high GHSV of 42,000h-1. The improved performance of the catalyst is correlated with its easier reducibility.
