  2. 36. Imine/azo-linked microporous organic polymers : Design, synthesis and applications

    Author : Chao Xu; Niklas Hedin; Dave Adams; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Microporous organic polymers; CO2 capture and separation; post-modification; chemisorption; heterogeneous catalysis; Materials Chemistry; materialkemi;

    Abstract : Microporous organic polymers (MOPs) are porous materials. Owing to their high surface area, tunable pore sizes and high physicochemical stability, they are studied for applications including gas capture and separation and heterogeneous catalysis. In this thesis, a series of imine/azo-linked MOPs were synthesized. READ MORE

  4. 37. The chemical nature of CO2 adsorption in zeolite A

    Author : Przemyslaw Rzepka; Niklas Hedin; Webley Paul; Stockholms universitet; []
    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; Materials Chemistry; materialkemi;

    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

  5. 38. Opportunities for CO2 Reductions and CO2-Lean Energy Systems in Pulp and Paper Mills

    Author : Kenneth Möllersten; KTH; []
    Keywords : CO2 reduction; pulp and paper industry; energy system; biomass; CO2 capture and sequestration; black liquor; gasification; power production; outsourcing; sustainable energy management;

    Abstract : The risk for climate change is a growing concern for theglobal society. According to what is known as the Kyoto Protocol,developed countries have committed themselves to reduce theirgreenhouse gas (GHG) emissions. The purpose of this thesis hasbeen to analyse opportunities for CO2 reductions in Swedish pulpand paper mills. READ MORE

  6. 39. Sustainable porous organic materials : Synthesis, sorption properties and characterization

    Author : Fredrik Björnerbäck; Niklas Hedin; Knut Irgum; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; porous materials; sorbents; microporous; CO2 capture and separation; gas adsorption; activated carbon; humins; hypercrosslinked polymers; sustainable; Materials Chemistry; materialkemi;

    Abstract : The resources available to us humans, including metals, minerals, biomass, air, water, and anything else on the planet, are being used at an increasing rate. This anthropogenic use of resources both depletes the resources and has negative impacts on other resources, e.g. the biosphere. READ MORE

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

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

    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.
