The bimetallic modified Y zeolite is of great importance for the deep removal of thiophene in coking benzene. Among them, the influence of metal ion-exchange sequence on the desulfurization performance of zeolite is crucial. Therefore, a series of bimetallic modified sorbents were prepared by the ion-exchange method using Cu and Ce in this paper. The desulfurization performance of sorbents in thiophene-benzene solutions were evaluated by static adsorption experiments. The physical and chemical properties of sorbents were analyzed by XRD, Py-FTIR, XPS, H 2 -TPR and N 2 adsorption and desorption techniques. The results show that metal ion-exchange sequence affects the relative crystallinity, ion-exchange degree, metal content and L acid amount of sorbent. The correlation between the physical and chemical properties and the desulfurization performance of sorbent was found that the higher ion-exchange degree, the higher the desulfurization efficiency of sorbent. Meanwhile, the more Cu + and Ce 4+ in the sorbent, the more L acid sites are formed and the higher its desulfurization efficiency. When Y zeolite is exchanged by Ce first and then Cu,the metal Ce affects the location of Cu and improves reduction performance of Cu. The desulfurization

efficiency of sorbents are CuCeY>CeCuY>Cu-CeY. The desulfurization efficiency of CuCeY is the highest,reaching 97.3%, and its relative crystallinity is the highest and ion-exchange degree is the largest. This work serves as a guide for the preparation of highly efficient desulfurization sorbents.
