摘要
介绍了纳米ZSM-5分子筛的合成及其在直馏汽油非临氢改质中的应用、纳米β分子筛的合成及其在苯与乙烯液相烷基化中的应用、纳米空心钛硅分子筛(HTS)的合成及其在环己酮氨肟化过程中的应用以及纳米Silicalite-1分子筛的合成及其在环己酮肟气相贝克曼重排生产己内酰胺中的应用,并简要综述了上述纳米分子筛合成和应用方面的最新研究进展. 结果表明,对于炼油和石油化工中易结焦失活的催化反应过程,分子筛的纳米化可抑制催化剂快速失活,延长催化剂寿命.
Nanosized ZSM‐5 was synthesized and used for straight run gasoline reforming.Nanosized β was synthesized and used for the alkylation of benzene and ethylene in ethylbenzene production.Nanosized titanosilicate molecular sieve with a hollow structure（HTS） was synthesized and used for the oximation of cyclohexanone.Nanosized silicalite‐1 was synthesized and used for the gas phase Beckmann rearrangement of cyclohexanone oxime in caprolactam production.Recent progress in the synthesis and application of nanosized ZSM‐5,β,TS‐1,and silicalite‐1 were reviewed.The catalyst lifetimes were prolonged when nanosized molecular sieves were used as petroleum refining and petrochemical catalysts.
