  • The influences of temperature, sulfur dioxide concentration and space velocity on the regeneration behavior of modified semi-coke supported Fe/Zn/Ce sorbent were investigated in a quartz fixed-bed reactor of 20 mm diameter. The sorbents were prepared by co-precipitation method with the Zn/Fe/Ce molar ratio of 1.0:2.0:0.6 supported on the modified semi-coke. The changes of crystalline phase and morphology of the sorbent before and after regeneration were examined by X-ray diffraction and scanning electron microscopy. The surface area and pore volume of sorbents were characterized by N2 adsorption. The results show that the sorbent can be regenerated over 600 ℃ and the elemental sulfur is produced. The optimum regeneration temperature, SO2 concentration and space velocity are 700 ℃, 12% and 5 000 h-1, respectively.
