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

    Author : Sang Wirawan; Chalmers University of Technology; []
    Keywords : composite membranes; TPD; MFI zeolites; WGS membrane reactor; adsorption; FTIR spectra;

    Abstract : 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. READ MORE

  3. 3. Factors affecting MFI membrane quality

    Author : Charlotte Andersson; Luleå tekniska universitet; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Chemical Technology; Kemisk teknologi;

    Abstract : Zeolites are crystalline aluminosilicates with molecular sieving properties and are widely used in industrial applications such as catalysis, sorption and ion-exchange. Zeolite membranes are highly interesting due to their capability to continuously separate molecules under severe conditions. READ MORE

  4. 4. Tuned acidity in zeotypes: A descriptor to unravel the direct conversion of methane to methanol

    Author : Simone Creci; Chalmers University of Technology; []
    Keywords : methanol; catalysis; MFI; infrared spectroscopy; methane; zeotype; zeolite;

    Abstract : The catalyst's acidity is crucial in countless chemical reactions, and thus to tune this parameter means to take the lead on the desired catalytic reaction. Therefore, it is not surprising that zeolites have been used since decades as catalysts for their outstanding properties of solid acids. READ MORE
