摘要: Lignite char supported Fe–Zn–Cu sorbents were prepared by ultrasonic-assisted impregnation method for the simultaneous removal of H2S and COS from coke oven gas (COG). Sulfidation experiments carried out in a fixed-bed quartz reactor using simulated COG. The results showed that addition Cu can significantly increase sulfidation reactivity char-supported Fe–Zn sorbents. Char-supported with Fe:Zn:Cu molar ratio 2:1:0.5 could simultaneously remove temperature range 200–400°C. sulfur capacity reached to 17.62 g S per 100 sorbent at 400°C. X-ray diffraction (XRD) analysis suggested into leads formation composite oxides. © 2015 American Institute Chemical Engineers Environ Prog, 35: 352–358, 2016
