  1. 16. In pursuit of clean air through numerical simulations of no-waste pollutant removal

    Författare :Marc Rovira; Christophe Duwig; Klas Engvall; Matthew Johnson; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Air quality; SOx and NOx removal; Ozone oxidation; Aerosol particle formation; Large-eddy simulations; Reactive flows; Proper orthogonal decomposition; Machine learning; Sensitivity analysis; Engineering Mechanics; Teknisk mekanik;

    Sammanfattning : As epidemiological evidence continues to mount, it has become undeniable that exposure to high levels of airborne pollutants such as SOx and NOx are detrimental to human health. In recent years, millions of premature deaths by stroke, coronary heart disease, and lung cancer worldwide have been linked to poor outdoor air quality. LÄS MER

  2. 17. Fundamentals of NH3-SCR and SOx chemistry over copper zeolite for the control of NOx and greenhouse gas (N2O) emissions

    Författare :Joonsoo Han; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; DeNOx; Cu SSZ-13; NH3-SCR; N2O; EATS; SO3; ammonium nitrate; SO2;

    Sammanfattning : The release of N2O over Cu-zeolite was investigated due to the critical contribution it makes to the atmosphere as one of the greenhouse gases (GHGs). An exhaust after-treatment system (EATS) for heavy-duty vehicles that uses Cu/SSZ-13 as the selective catalyst reduction (SCR) catalyst experiences not only a variety of flow, temperature and chemical conditions but is also exposed to various resulting contaminants.

  3. 18. Chemistry and Process Design of Integrated Removal of Nitrogen and Sulfur oxides in Pressurized Flue Gas Systems

    Författare :Sima Ajdari; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : Carbon capture and storage is vital to reach the climate goals to limit the increase in the global temperature. Among the carbon capture technologies, oxy-fuel and chemical looping combustion produce a stream mainly containing carbon dioxide (CO2) and water but also contaminants such as nitrogen oxides (NOx) and sulfur oxides (SOx).

  4. 19. Reducing Alkali Chloride-Induced High Temperature Corrosion by Sulphur Containing Additives – A Combined Laboratory and Field Study

    Författare :Sofia Karlsson; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Sulphur; Stainless Steels; Additives; Biomass; Waste; High Temperature Corrosion; Alkali Chlorides; Co-combustion;

    Sammanfattning : In order to achieve a more sustainable society renewable fuels such as biomass and waste are attractive alternatives to fossil fuels for power production. However, fireside corrosion is a serious concern in boilers combusting biomass or waste. The high corrosion rates are often linked to large amounts of alkali chlorides in the flue gas. LÄS MER

  5. 20. Progression of RNA-sequencing to single-cell applications

    Författare :Daniel Ramsköld; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : New methods enable new discoveries. My time as a PhD student has run in parallel with the maturation of the RNA-seq method, and I have used it to discover basic properties of gene expression and transcriptomes. My part has been bioinformatics – the computer analysis of biological data. LÄS MER
