Abstract

Abstract:

CeY, AgY and CuY were prepared by two times of liquid ion-exchange and characterized by XRD, BET and ICP-MS. The isotherms of thiophene, benzene, octane, 1-octene were determined by an intelligent gravimetric analyzer and fitted by Langmuir equation. The results show that the isotherms of thiophene, benzene, octane over NaY, CeY, CuY and AgY at 29 ℃ can be well fitted by Langmuir equation, and the isotherms of 1-octene over NaY, CuY and AgY at 29 ℃ also can be fitted by Langmuir equation, while, the isotherms of 1-octene over CeY at 29 ℃ are deviated from Langmuir equation. 

Key words: Y zeolite, Ion exchange, Adsorption, Langmuir

摘要： 用2 次离子交换和2 次焙烧的方法制备了CeY 、AgY 和CuY 分子筛, 并用X 射线衍射仪(XRD)、比表面分析仪(BET)、电感耦合等离子体质谱(ICP -MS)对其进行了表征。研究了噻吩、苯、正辛烷、1 -辛烯在NaY、 CeY、AgY 和CuY 上的吸附等温线, 并用Langmuir 方程进行了拟合。结果表明, 29 ℃时噻吩、苯、正辛烷在NaY、 CeY、AgY 和CuY 上的吸附等温线都能被Langmuir 方程很好的拟合;29 ℃时1-辛烯分别在NaY 、AgY 和CuY 上的吸附等温线也能被Langmuir 方程很好的拟合;1 -辛烯在CeY 上的吸附等温线偏离Langmuir 方程。
