摘要:
用巨正则系综蒙特卡罗(GCMC)和构型偏倚蒙特卡罗(CBMC)相结合的分子模拟方法,研究了正戊烷在ZSM系分子筛[MFI(ZSM5)、MEL(ZSM11)、MTW(ZSM12)]上的吸附性质,模拟的吸附热和文献结果一致,相对误差为4.8%.在此基础上,模拟了吸附热、Henry常数、吸附等温线、吸附位等吸附性质,并利用双点Langmuir等温线方程对吸附等温线进行拟合,得到了双点Langmuir等温线参数.
Abstract:
Grand Canonical Monte Carlo(GCMC) simulations and ConfigurationalBias Monte Carlo(CBMC) simulations have been used for investigating the adsorption properties of npentane in ZSM series zeolites, such as MFI(ZSM5)、MEL(ZSM11) and MTW(ZSM12). The simulated isosteric heat of adsorption was in good agreement with the experimental data reported in literatures and the relative error was 4.8%. Based on these facts, other properties such as isosteric heat of adsorption, Henry`s law constants, adsorption isotherms, potential sites of adsorption were predicted. The adsorption isotherms were described by the dualsite Langmuir equation and the parameters in dualsite Langmuir mode obtained.
