The various type and strength energy barrier was structured by the modified    molecular sieve. The adsorption and diffusivity performance of object adsorption molecular on the chose absorbent under the different temperature and pressure were determined. The results show that with the CuO mass fraction increase, the adsorptive capacity of ethylene in CuO/HMor first increases and then decreases. With the Cs+ mass fraction increase, total adsorptive capacity of ethylene in Cs+/HMor increases, high frequency adsorptive capacity increases, low frequency adsorptive capacity decreases. Compared adsorption capacity derived from the frequency response spectra with adsorption capacity derived from the intelligent gravimetric analyser, consequently adsorption mechanism which was explanded by frequency response method is reliability.

A software platform for the optimization of frequency response characteristic function used for the characterization of catalysts has been developed based on LabVIEW.The optimization algorithm of simplex algorithm and Powell method were introduced, as well as fundamental principles refer to catalyst models and objective functions. The flow chart of program platform was presented. Design procedures, the graphic programs and some other techniques for main program VI and model configuration, simplex method, theory model, etc. were also described.
