  2. 16. Thermodynamic Properties of CO2 Mixtures and Their Applications in Advanced Power Cycles with CO2 Capture Processes

    Author : Hailong Li; Jinyue Yan; Umberto Desideri; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Thermodynamic property; vapour liquid equilibrium; density; equation of state; interaction parameter; CO2 mixtures; evaporative gas turbine; chemical absorption; oxy-fuel combustion; cost evaluation; CO2 capture and storage; Chemical engineering; Kemiteknik;

    Abstract : The thermodynamic properties of CO2-mixtures are essential for the design and operation of CO2 Capture and Storage (CCS) systems. A better understanding of the thermodynamic properties of CO2 mixtures could provide a scientific basis to define a proper guideline of CO2 purity and impure components for the CCS processes according to technical, safety and environmental requirements.

  4. 17. Modeling of geohydrological processes in geological CO2 storage – with focus on residual trapping

    Author : Kristina Rasmusson; Auli Niemi; Fritjof Fagerlund; Rainer Helmig; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; capillary trapping; CCS; characterization test; CO2; injection design; pore-network model; Hydrology; Hydrologi;

    Abstract : Geological storage of carbon dioxide (CO2) in deep saline aquifers is one approach to mitigate release from large point sources to the atmosphere. Understanding of in-situ processes providing trapping is important to the development of realistic models and the planning of future storage projects. READ MORE

  5. 18. Refixation of respiratory CO2 in leaves

    Author : Diana Eckert; Anna M. Jensen; John Marshall; Linnéuniversitetet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; CO2 refixation; mesophyll resistance; stomatal conductance; Vcmax; leaf anatomy; photosynthesis; forestry; carbon allocation; ecophysiology; Natural Science; Naturvetenskap;

    Abstract : Photosynthesis is a vital process for trees, one in which CO2 plays a major role. At the same time, the tree’s own metabolism produces CO2. READ MORE

  6. 19. Theoretical Studies on CO2 Reduction Electrocatalysts

    Author : Xiaoyu Chen; Mårten S. G. Ahlquist; Sandra Luber; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Computational Chemistry; CO2 reduction; electrocatalysis; Teoretisk kemi och biologi; Theoretical Chemistry and Biology;

    Abstract : The atmospheric CO2 concentration has increased by more than 20% since 1980s and has now reached the highest level than at any point in the past 800 000 years. Electrochemical CO2 reductions are receiving particular in- terest as the apparatus are relatively easy to maintain and cheap to operate. READ MORE

  7. 20. Pathways for the European electricity supply system to 2050 – Implications of stringent CO2 reductions

    Author : Mikael Odenberger; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; abatement; Electrcity supply system; CO2;

    Abstract : This thesis, which consists of four separate papers, investigates possible pathways forthe European electricity supply systems to meet stringent CO2 emission reductions.Assessments are made for single EU member states, selected regions and the EU as awhole. READ MORE
