对苯在B-ZSM-5、Silicalite、Fe-ZSM-5中的扩散进行了研究。结果表明,迎头色谱法与重量法结果一致,说明了迎头色谱结果的可靠性。本文扩散系数结果支持前人在大晶粒ZSM-5上得到的结果。
The diffusion of benzene in B-ZSM-5, Silicalite, Fe-ZSM-5 was studied. The results showed that in-head chromatography was consistent with gravimetric results, demonstrating the reliability of the heads-up chromatographic results. The results of the diffusion coefficient in this paper support the previous results obtained on the large grain ZSM-5.
