  1. 1. Gas Adsorption and Permeation in MFI Zeolites and Membranes

    Författare :Sang Wirawan; [2009]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; composite membranes; TPD; MFI zeolites; WGS membrane reactor; adsorption; FTIR spectra;

    Sammanfattning : The single and multi component gas adsorption behavior on silicalite-1 and cation exchanged MZSM-5 zeolites (M = H, Na, and Ba) were investigated by a step change response method. Temperature programmed desorption (TPD) and in-situ fourier transform infrared (FTIR) spectroscopy were also performed to study the type of adsorbed species and their thermal stabilities. LÄS MER
