Cerium incorporated MCM-22 (Ce-MCM-22) was successfully synthesized by hydrothermal method. Incorporation of Ce is achieved by the optimization of method for synthesis by varying (i) Concentration of sructure directing agent or template, (ii) Silica to ceria ratio and (iii) Crystallization time. Change in phases during crystallization, variation of physico-chemical properties with respect to gel composition and framework substitution of cerium are evidenced by XRD, UV–Vis DRS, SEM, N₂ adsorption, FT-IR, Ammonia TPD and solid-state MAS-NMR characterisations. It is found that incorporation of Ce into the zeolite frame work has successfully occurred by simple method of optimisimg molar gel composition. Interestingly, prepared samples of Ce-MCM-22 have also been found to be more effective catalysts for the removal of trace olefins from aromatic streams.

通过水热法成功地合成了掺铈的MCM-22（Ce-MCM-22）。通过改变（i）结构导向剂或模板的浓度，（ii）二氧化硅对二氧化铈的比例和（iii）结晶时间来优化合成方法，从而实现Ce的掺入。XRD，UV-Vis DRS，SEM，N ₂证明了结晶过程中的相变，相对于凝胶组成的物理化学性质变化以及铈的骨架取代。吸附，FT-IR，氨TPD和固态MAS-NMR表征。已发现通过优化摩尔摩尔凝胶组成的简单方法已成功地将Ce掺入沸石骨架中。有趣的是，还发现制备的Ce-MCM-22样品是从芳族烃流中去除痕量烯烃的更有效催化剂。
