摘　　要：以淀粉为模板剂,制备出多级孔Y型分子筛,并用Ce(NO)3对其进行了改性。借助X射线衍射仪、扫描电子显微镜、傅里叶变换红外光谱仪(KBr和吡啶)等对分子筛物相、酸性和孔道结构进行了表征。结果表明,多级孔Y型分子筛具有一定数量孔径约为30 nm的介孔,并且介孔孔容随着淀粉加入量增加而增大;改性后多级孔Ce Y型分子筛的脱硫效果优于常规Ce Y者。A hierarchical porous zeolite Y was synthesized by using starch as co - template, and modified by Ce （NO） 3- The physical properties, acid- ity and pore structure of hierarchical zeolite Y were characterized by X -ray diffraction, scanning electron microscope, Fourier transform infrared spectroscope （with KBr and pyridine adsorption ）. The results showed that there was a certain amount of 30 nm - sized mesopores inside the zeolite Y, and their meso- porous volume increased with increasing starch amount. The desulfurization performance of hierarchi- cal CeY was better than that of conventional CeY.
