  1. 11. Structured zeolite adsorbents for PSA applications

    Författare :Alessandra Mosca; Joeri Denayer; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Chemical Technology; Kemisk teknologi;

    Sammanfattning : Zeolites are microporous crystalline aluminosilicates with unique properties, and are therefore used in adsorption processes, for membrane separation, and as catalysts. Thin zeolite films grown on honeycomb monolith supports represent a new type of material and may be used as structured catalysts and adsorbents, and improve the processes significantly. LÄS MER

  3. 12. 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

  5. 14. Processing and performance of zeolites for efficient carbon dioxide separation

    Författare :Arto Ojuva; Lennart Bergström; Viveka Alfredsson; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Materials Chemistry; materialkemi;

    Sammanfattning : We have structured zeolites from powders of zeolite 13X and 4A into hierarchically porous monoliths for efficient carbon dioxide capture by tailoring the pore dimensions to facilitate rapid gas uptake and release. Freeze-casting was used for the first time to shape adsorbents into a lamellar structure. LÄS MER

  7. 15. Synthesis and applications of low silica zeolites from Bolivian clay and diatomaceous earth

    Författare :Javier Gustavo Garcia Mendoza; Johanne Mouzon; Niklas Hedin; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Zeolites; Synthesis; clay; diatomite; adsorption; ion exchange; Chemical Technology; Kemisk teknologi;

    Sammanfattning : The aim of the present work was to develop synthesis routes to produce synthetic zeolites with industrial attractiveness from non-expensive Bolivian raw materials, such as clays and diatomite. In particular, the work was focused on the synthesis of low-silica zeolites with the LTA and FAU structures. LÄS MER
