【摘要】 由于微孔分子筛SSZ-13具有独特的物理化学性质,使其在越来越多的领域显示出广阔的应用前景,近年来成为研究的热点。本文综述了利用不同模板剂制备SSZ-13分子筛的研究进展,并评价了这些方法的优缺点,从而为降低N,N,N-三甲基金刚烷铵(TMADa+)的用量或者完全替换为廉价模板剂,最终实现SSZ-13分子筛的工业化生产提供思路;总结了SSZ-13分子筛在脱除汽车尾气NOx、甲醇制低碳烯烃(MTO)以及气体分离吸附过程中的应用研究进展,尽管SSZ-13分子筛在这些领域显示出很好的性能,但仍存在SCR高温催化活性有待进一步提高、MTO反应中易积碳等问题。最后指出,对SSZ-13负载双金属、降低酸性中心强度以及进行机理研究等将成为SSZ-13分子筛今后研究的重点。更多还原

【Abstract】 As a kind of microporous molecular sieve,SSZ-13 has a broad application prospect owing to its unique physical and chemical properties and has become a hot research topic. In order to decrease the dosage of N,N,N-trimethyl-1-adamanthyl ammonium(TMADa+) or use inexpensive templates,the progress of its synthesis with different templates is reviewed,and the advantages and disadvantages of these methods are discussed. The progress of application of SSZ-13 is also presented. Although SSZ-13 shows superior performance in NOx abatement,methanol to olefin(MTO) and adsorption and separation of gas,there are still problems which need to be resolved. Therefore,bimetallic SSZ-13 catalyst,reduction of acid site strength and mechanism research will be the focus in the future.更多还原
