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

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

    Sammanfattning : 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.
