摘　　要：本文采用水热处理法对 NaFe ZSM-5分子筛进行改性,考查了分子筛中铁的状态与高温水热处理的关系,研究乙苯在 NaFe ZSM-5分子筛上的吸附扩散性质,以及水热处理对 NaFe ZSM-5分子筛的催化脱氢活性的影响.In this paper,we have used steaming treatment method to change the properties of NaFeZSM-5 type molecular sieves,and studied the relationship be- tween the state of Fe atom in molecular sieves and high temperature steaming.The adsorption and diffusion properties of ethylenebenzene on NaFeZSM-5 molecular sie- ves were studied,and the effect of steaming treatment on catalytic dehydrogenation of NaFeZSM-5 molecular sieves was carefully examined.
