Description: Lignite char supported Fe-Zn sorbents were prepared by means of impregnation of Fe and Zn into coal followed by steam gasification. The sulfidation experiments were carried out using a fixed-bed quartz reactor in the temperature range of 473 to 673 K using simulated coke oven gas with a gas space velocity of 1,000 h⁻¹. Strcuture changes of sorbents during sulfidation were analyzed using X-ray diffraction and scanning electron microscopy. The results show that the sorbents can remove both H₂S and coke oven gas from the simulated coke oven gas with high efficiency, and the desulfurization efficiency increased with increasing metal loading level.
