  1. 6. Development of a novel zeolite coated ATR-FTIR sensor

    Författare :Mattias Grahn; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Chemical Technology; Kemisk teknologi;

    Sammanfattning : Thin zeolite films have great potential in several novel application areas such as: structured catalysts, membranes and sensors. To fully exploit the advantages of these films it is of great importance to determine the properties of the films. LÄS MER

  3. 7. Gas Adsorption and Permeation in MFI Zeolites and Membranes

    Författare :Sang Wirawan; Chalmers tekniska högskola; []
    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

  4. 8. A vibrational spectroscopy study of the growth of silicate-1 films on noble metal surfaces

    Författare :Vania Engström; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Chemical Technology; Kemisk teknologi;

    Sammanfattning : The main objective of this thesis was to acquire a better understanding of the mechanisms involved in the preparation of Silicalite-1 films in general and on gold surfaces in particular. Molecular sieve films on gold surfaces were prepared using the seed film method. LÄS MER

  5. 9. Modification of MFI membranes for enhanced selectivity

    Författare :Jonas Lindmark; Ann-Sofi Jönsson; Luleå tekniska universitet; []
