摘要

In this work, Zr-M (M=Cu, Mn, Ce) type sulfur transfer agent was prepared by impregnation method. Under the condition similar to that in the regenerator of FCC units, the inlfuence of different active metal components and their con-tents on sulfur transfer agent were investigated. Moreover, the crystalline structure of sulfur transfer agent was characterized by X-ray diffraction (XRD) and Fourier transforms infrared spectroscopy (FT-IR). The result showed that the Zr-Mn sulfur transfer agent could effectively reduce the SO2 content in FCC regenerator lfue gas, featuring high SO2 adsorption capacity. The sulfur transfer agent was inactivated in 40-60 min during the test. In the course of reduction reaction, after several re-action cycles, the formation of SO2 ceased and only H2S was detected as the reduction product.
