Abstract
To develop a highly active COS sorbent, Fe–Mn mixed oxide doped with La and Sm were studied. The effects of promoters on the Fe–Mn oxides were investigated by XRD, BET and other methods. XRD results revealed that the degree of crystallinity and particle size of Fe–Mn oxide phase decreased due to doping with La2O3 and Sm2O3. Addition of rare-earth oxides led to a progressive increase in the surface area of the sample. Desulfurization tests showed that the addition of 3 wt % La2O3 and Sm2O3 greatly improved the absorption sulfur capacity of the sorbent for COS removal.
