摘要: 在丁烯异构化反应催化剂中,镁碱沸石分子筛由于具有十元环和八元环交错的独特的二维孔道结构、良好的水热稳定性和化学稳定性、较高的选择性等诸多优点受到广泛关注;但由于有机模板剂的影响,在环境友好方面有所欠缺。本文综述了镁碱沸石(FER)的合成方法:有机模板剂合成法、非模板剂合成法、层状前体合成法、乳化剂控制合成法,归纳比较了各种合成方法的优缺点,阐述了FER的合成后处理方式,指出采用无毒无害的原材料替代有机合成模板剂,从而提高镁碱沸石分子筛的催化性能,对环境友好大大改善,是未来研究镁碱沸石分子筛催化剂的发展方向之一。

Abstract: FER zeolites are of great importance in materials field due to their unique two-dimensional pore system consisting of 10-ring channels intersected by 8-ring channels and excellent chemical and hydrothermal stability in comparison with other zeolite catalysts. More recently,FER zeolites have attracted great attention because of their remarkable catalytic performance and high shape selectivity for the skeletal isomerization of 1-butene to isobutene. However,FER needs further improvement to be environment-friendly due to the impact of organic templating agent. Different synthesis pathways of FER,including organic template synthesis,non-template synthesis,layered precursor synthesis,emulsifier controlled synthesis and post-treatment of synthesized FER zeolites,are reviewed,and the future development and application of FER is also prospected. There is a good research potential using non-toxic raw materials replace organic template for the synthesis of FER,which will greatly improve its environment-friendliness and also improve the catalytic performance of the zeolite.
