| 摘 要： | 采用廉价的硅溶胶作为硅源,吡咯烷为模板剂,静态水热晶化法合成出不同硅铝比的ZSM-23分子筛.采用XRD,SEM,吡啶吸附红外光谱等技术,对合成的ZSM-23分子筛的结构、形貌、表面酸性质进行了表征.并进行了所制样品对C4烷烃催化裂解制乙烯丙烯反应催化性能的研究.本文详细考察了硅铝比、反应温度、反应空速以及催化剂稳定性等各种因素对催化性能的影响.结果表明,ZSM-23分子筛的乙烯丙烯收率达到56.0%,丁烷转化率达到88.9%.

| Abstract: | Pure and well crystallized zeolite ZSM-23 zeolite with different Si/Al ratio were prepared under static hydrothermal conditions using pyrrolidine as template,colloidal silica as source of silica.The samples obtained were characterized by powder X-ray diffraction(XRD),N2 adsorption/desorption,scanning electron microscopy(SEM),and FTIR of adsorbed pyridine,and was very efficient and stable catalysts for the catalytic cracking of C4 alkane.The highest C4 alkane conversion of 88.9% and the total yields of ethylene and propylene of 56.0% were obteined. |
