  1. 1. Numerical simulations of industrial-scale packed-bed adsorbers

    Författare :Adam Jareteg; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Packed Bed; Numerical Modeling; Temperature Swing Adsorption; Finite Volume Method; Industrial Scale;

    Sammanfattning : A common technique for removing harmful substances, for either persons or equipment, from a stream is to use the phenomenon of adsorption. This technique is used in, for example, water purification, personal protection, chemical and pharmaceutical production and biomass gasification. LÄS MER

  3. 2. 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

  4. 3. Structured zeolite adsorbents

    Författare :Alessandra Mosca; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Chemical Technology; Kemisk teknologi;

    Sammanfattning : Zeolites are microporous crystalline aluminosilicates with unique properties, and therefore used in adsorption processes, for membrane separation, in catalysis, and in sensor technologies. Pressure swing adsorption (PSA) is a commonly used technology for purifying gases and is based on the ability of materials like zeolites, to selectively adsorb and desorb particular gas molecules as the gas pressure is increased and reduced, respectively.

  5. 4. Multi-scale analyses of cycled industrial-scale packed-bed adsorbers

    Författare :Adam Jareteg; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : Separations processes account for 10%–15% of the total energy consumed in process industries worldwide. In such separation processes, it is common to use activated carbon in packed-bed adsorbers, to remove undesired substances from a process stream. LÄS MER

  7. 5. Bio-SNG from Thermal Gasification - Process Synthesis, Integration and Performance

    Författare :Stefan Heyne; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; process integration; process modelling; performance indicators; biomass; energy systems; synthetic natural gas; gasification;

    Sammanfattning : Biomethane or synthetic natural gas (Bio-SNG) produced from gasified renewable woody biomass is a promising option for replacing fossil natural gas. The complete interchangeability with natural gas in all its conventional applications such as in the power generation, transportation and chemical industry sector is of particular interest. LÄS MER
