- Description
- 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 were carried out in a fixed-bed quartz reactor using simulated COG. The results showed that the addition of Cu can significantly increase the sulfidation reactivity of char-supported Fe–Zn sorbents. Char-supported Fe–Zn–Cu sorbents with Fe:Zn:Cu molar ratio of 2:1:0.5 could simultaneously remove H₂S and COS in the temperature range of 200–400°C. The sulfur capacity reached to 17.62 g S per 100 g sorbent at 400°C. The X-ray diffraction (XRD) analysis suggested that the addition of Cu into the Fe–Zn sorbent leads to the formation of composite oxides.
