Effect of Rare Earth for Removal of Carbonyl Sulfide from Synthesis Gas

Abstract:

Fe-Mn metal oxides nanosized particles have been prepared by doping with La. The effects of promoters on the oxides were investigated by XRD, BET and other methods. XRD results revealed that the degree of crystallinity and particle size of mixed oxide phase decreased due to doping with La₂O₃. Addition of La led to a progressive increase in the surface area of the sample. Tests showed that the addition of 3 wt % La₂O₃ greatly improved the absorption sulfur capacity of the sorbent for COS removal. Keywords: Hydrogen utilized; Carbonyl Sulfide; Doping; La₂O₃
