Ce-doped nanosized ZnO desulfurizer was prepared by homogeneous precipitation, and its desulfurization efficiency at ambient temperature was investigated through dynamic experiments. The results showed that the desulfurization activity of nanosized Ce-ZnO had improved greatly, compared to nanosized ZnO desulfurizer. Nanosized Ce-ZnO desulfurizer was characterized by XRD, TPD-MS, XPS, and TEM. The research results indicated that doping Ce decreased the particle size of the nanosized ZnO desulfurizer and ZnS was the principal desulfurization product. There were adsorption complexes of HS and S on the surface of desulfurizer as well. Only a small amount of vapor appeared in the tail gas on the condition of meeting the precision of desulfurization.
