| description | The invention discloses a mesoporous Beta-USY type composite molecular sieve as well as a preparation method and application thereof. The mesoporous Beta-USY type composite molecular sieve has two crystal forms, namely a Y type molecular sieve and a Beta type molecular sieve; wherein the Beta molecular sieve is used as a nuclear phase, and the diameter of the nuclear phase is 50-500nm; a Y-type molecular sieve is used as a shell phase, and the thickness of the shell phase is 50-1000nm. The mesoporous Beta-USY type composite molecular sieve provided by the invention is used as a liquid-phase transalkylation catalyst, and can improve the diffusion of reactants and products in the catalyst, enhance the reaction activity and selectivity of the catalyst, optimize the product distribution and reduce the occurrence of side reactions.
本发明公开了一种介孔Beta-USY型复合分子筛及其制备方法与应用。所述介孔Beta-USY型复合分子筛具有两种晶型，分别为Y型分子筛和Beta型分子筛；其中，以Beta分子筛为核相，核相直径尺寸为50-500nm；以Y型分子筛为壳相，壳相厚度为50-1000nm。本发明提供的介孔Beta-USY型复合分子筛用作液相烷基转移催化剂，能够提高反应物和产物在催化剂中的扩散 |
