Abstract In this paper, mesoporous silica based adsorbents were synthesized and evaluated for the desulfurization of flue gas streams. KIT-6 mesoporous silica was impregnated with CuO, CeO2 and CuO-CeO2. The materials were characterized by XRD, N2 adsorption–desorption, SEM, TEM and XPS analysis. The activity of the obtained adsorbents was evaluated at 400 °C with a GHSV (Gas Hourly Space Velocity) of 25,000 h−1 for the removal of SOx from gas streams. The results show that the co-impregnation of copper and cerium on KIT-6 results in a synergistic effect in terms of SO2 removal.
