  2. 2. The chemical nature of CO2 adsorption in zeolite A

    University dissertation from Stockholm : Department of Materials and Environmental Chemistry, Stockholm University

    Author : Przemyslaw Rzepka; Niklas Hedin; Webley Paul; [2019]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; CO2 adsorption; flue gas CO2 capture; biogas upgrading; zeolite |NaK|-A; physisorption; chemisorption; kinetic separation; in situ diffraction; synchrotron XRD; NPD; NMR; IR; materialkemi; Materials Chemistry;

    Abstract : The climate changes are accelerated by increasing levels of carbon dioxide in the atmosphere connected to the fossil-fuel-based energy system. Substantial reforms of the system are needed immediately and could include the implementation of carbon capture and storage (CCS) technologies. READ MORE

  3. 3. Narrow-pore zeolites and zeolite-like adsorbents for CO2 separation

    University dissertation from Stockholm : Department of Materials and Environmental Chemistry (MMK), Stockholm University

    Author : Ocean Cheung; Niklas Hedin; Paul A. Wright; [2014]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; CO2 separation; zeolites; phosphates; titanium silicates; ion exchange; flue gas CO2 capture; biogas upgrading; materialkemi; Materials Chemistry;

    Abstract : A range of porous solid adsorbents were synthesised and their ability to separate and capture carbon dioxide (CO2) from gas mixtures was examined. CO2 separation from flue gas – a type of exhaust gas from fossil fuel combustion that consists of CO2 mixed with mainly nitrogen and biogas (consists of CO2 mixed with mainly methane) were explicitly considered.

  4. 4. Cellulose Nanofibril-based Hybrid Materials Eco-friendly design towards separation and packaging applications

    University dissertation from Stockholm : Department of Materials and Environmental Chemistry, Stockholm University

    Author : Luis Valencia; Aji Mathew; Olli Ikkala; [2019]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Cellulose nanofibrils; hybrid materials; membranes; aerogels; separation; food packaging; materialkemi; Materials Chemistry;

    Abstract : Nanocellulose has been lately considered as the “Holy-Grail” in the design of sustainable materials due to its bio-origin and an unprecedented combination of prominent features, including good mechanical properties, anisotropy and versatile surface chemistry. In addition, nanocellulose in the form of cellulose nanofibrils, can adopt variable structures and morphologies depending on the processing technique, such as aerogels, films and monoliths.

  5. 5. Structuring porous adsorbents and composites for gas separation and odor removal

    University dissertation from Stockholm, Sweden : Department of Materials and Environmental Chemistry (MMK), Stockholm University

    Author : Neda Keshavarzi; Lennart Bergström; Kurosch Rezwan; [2014]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Structure; pulsed current processing; zeolite; aluminophosphate; activated carbon; CO2 separation; adsorption; durability; cellulose; film; coating; materialkemi; Materials Chemistry;

    Abstract : Porous zeolite, carbon and aluminophosphate powders have been colloidally assembled and post-processed in the form of monoliths, flexible free standing films and coatings for gas separation and odor removal. Zeolite 13X monoliths with macroporosites up to 50 vol% and a high CO2 uptake were prepared by colloidal processing and sacrificial templating. READ MORE
