  2. 11. Synthesis and Applications of Colloidal Zeolites and Transition Metal Functionalized Ordered Mesoporous Carbons

    Author : Walter Rosas Arbelaez; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; colloidal zeolites; CO2 capture; hierarchical zeolites; growth mechanism; Fe-N-doped ordered mesoporous carbon; fuel cell.;

    Abstract : Porous materials have attracted a great deal of attention of the materials science community, owing to their physical and chemical properties including high surface areas, narrow pore size distribution, tunable pore diameters and variety of chemical compositions. These properties make them suitable for various applications such as adsorption, sensing, catalysis, energy, carbon capture and drug delivery. READ MORE

  4. 12. Impacts of Thermo-Physical Properties on Chemical Absorption for CO2 Capture

    Author : Worrada Nookuea; Jinyue Yan; Hailong Li; Eva Thorin; Bin Liang; Xiaoyan Ji; Jesus Zambrano; Mälardalens högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energy- and Environmental Engineering; energi- och miljöteknik;

    Abstract : Following the climate change mitigation target in Paris agreement, the global warming has to be limited to 2.0°C above the preindustrial levels. One of the potential methods is carbon capture and storage (CCS), which can significantly reduce the CO2 emissions from the vast point sources such as power plants, industries, and natural gas processes.

  5. 13. CO, CO2 and N2 hydrogenation reactions probed by operando x-ray photoelectron spectroscopy

    Author : David Degerman; Anders Nilsson; Miquel Salmeron; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Operando Catalysis; Hydrogenation reactions; High-Pressure X-Ray Photoelectron Spectroscopy; Syngas; kemisk fysik; Chemical Physics;

    Abstract : Catalytic reactions are essential for generating the chemical products required by the modern society. In particular, reactions related to clean energy storage and generation as well as fertilizer production are facilitated by catalysts. However, the processes are often insufficiently understood at a mechanistic level. READ MORE

  6. 14. On the Extraction of Essential Oils by Supercritical Carbon Dioxide and its Influence on the Mesomorphic Phase Structures

    Author : José da Cruz Francisco; Kemiska institutionen; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Natural oils; fats and waxes technology; Naturliga oljor; fetter; vax; Kemiteknik och kemisk teknologi; Chemical technology and engineering; Livsmedelsteknik; Food and drink technology; phase behavior; soybean lecithin; monoolein; cineole; terpenes; eucalyptus; extraction; Essential oils; supercritical carbon dioxide;

    Abstract : A comparison of essential oils from leaves of Eucalyptus camaldulensis Dehn. obtained by hydrodistillation (HD) and supercritical carbon dioxide (SC-CO2) extraction is presented. Selected major components of the oils showed a predominance of higher molecular weight components in the SC-CO2 extracts than in those obtained by HD. READ MORE

  7. 15. Combustion of selected alternative liquid fuels at oxy-fuel conditions: experiments and modelling

    Author : Jenny D. Nauclér; Förbränningsfysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Alcohols; Nitromethane; Chemistry; Laminar burning velocity; Ignition; Combustion; Fysicumarkivet A:2016:Nauclér;

    Abstract : Combustion of fuels is a major source of energy and at the same time a threat to the environment. Carbon dioxide (CO2) emissions are one of the obstacles on the route to cleaner energy. Combining Carbon Capture and Storage-technology (CCS) with use of biofuels lead to a negative net release of CO2 can be achieved. READ MORE
