  2. 1. Reducing Carbon Dioxide Emissions from the EU Power and Industry Sectors - An assessment of key technologies and measures

    Author : Johan Rootzén; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; industry; carbon dioxide; cement; European Union; technologies; emission reductions; CCS; power; steel; CO2< sub>; refining; mitigation;

    Abstract : In February 2011, the European Council reconfirmed the goal of reducing EU greenhouse gas emissions by at least 80% by 2050, as compared to the levels in 1990. The power and industrial sectors currently account for almost half of the total GHG emissions in the EU. READ MORE

  4. 2. Mesoporous magnesium carbonate : Synthesis, characterization and biocompatibility

    Author : Sara Frykstrand Ångström; Maria Strømme; Johan Gómez de la Torre; Natalia Ferraz; Mika Lindén; Uppsala universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; mesoporous; magnesium carbonate; pore size control; cytotoxicity; in vivo; skin irritation; acute systemic toxicity; hemocompatibility; Ca2 uptake; solubility enhancement; Engineering Science with specialization in Nanotechnology and Functional Materials; Teknisk fysik med inriktning mot nanoteknologi och funktionella material;

    Abstract : Mesoporous materials constitute a promising class of nanomaterials for a number of applications due to their tunable pore structure. The synthesis of most mesoporous materials involves a surfactant liquid crystal structure to form the pores. READ MORE

  5. 3. Lipase-Catalysed Lipid Modifications in Supercritical Carbon Dioxide

    Author : Helga Gunnlaugsdottir; Livsmedelsteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; immobilisation support; enzymes; pressure; phase behaviour; flow rate; process parameters; supercritical carbon dioxide; Lipase; lipids; Food and drink technology; Livsmedelsteknik;

    Abstract : The production of ethyl esters (EE) from ethanol and cod-liver oil by an immobilised lipase in supercritical carbon dioxide (SCCO2) is described. This reaction results in a complex mixture of lipid components consisting of triglycerides, diglycerides, monoglycerides and ethyl esters. READ MORE

  6. 4. Hydrogen production from fossil fuels with carbon dioxide capture, using chemical-looping technologies

    Author : Magnus Rydén; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; chemical-looping combustion; carbon capture and storage; partial oxidation; Chemical-looping reforming; synthesis gas; hydrogen; steam reforming;

    Abstract : Carbon capture and storage have been receiving increasing interest lately, mainly as an option to reduce CO2 emissions from the power sector. The concept could be adapted for production of H2 as well, which would provide a carbon free energy carrier that could be used for example as transportation fuel. READ MORE

  7. 5. Reducing Swedish Carbon Dioxide Emissions from the Basic Industry and Energy Utilities : An Actor and Policy Analysis

    Author : Peter Stigson; Hans Lundberg; Jinyue Yan; Tobias Persson; Mälardalens högskola; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Sweden; climate change; climate policy; energy policy; EU ETS; Kyoto Protocol; emissions trading; renewable energy certificates; energy tax; carbon dioxide tax; voluntary agreements; environmental law; energy utilities; basic industry; Sverige; klimatförändringar; klimatpolitik; energipolitik; EU ETS; Kyotoprotokollet; utsläppshandel; el-certifikat; energiskatter; koldioxidskatt; frivilliga avtal; program för energieffektivisering; miljölagstiftning; energiproducenter; basindustri; INTERDISCIPLINARY RESEARCH AREAS; TVÄRVETENSKAPLIGA FORSKNINGSOMRÅDEN; Energy- and Environmental Engineering; energi- och miljöteknik;

    Abstract : The aim of the thesis is to analyze the design of the present climate and energy policies. The main focus is on how the policy instruments affect the Swedish stakeholders who are included in the European Union’s Emission Trading Scheme (EU-ETS). READ MORE
