Effect of Fe/Cu/Ce loading on the coal-based activated carbons for hydrolysis of carbonyl sulfide

Fe/Cu/Ce modified coal-based activated carbon(AC) was prepared by the sol-gel method,and the effect of Fe/Cu/Ce on catalytic properties of Fe/AC,Fe-Cu/AC and Fe-Cu-Ce/AC was investigated in the hydrolysis of carbonyl sulfide(COS) at 50 °C.Their surface properties were evaluated by means of nitrogen adsorption and were characterized by using scanning electron microscopy(SEM),X-ray diffracto-metry(XRD) and X-ray photoelectron spectroscopy(XPS).The catalytic activities results showed that addition of Cu and Ce...
