  3. 2. Leaching of Polycyclic Aromatic Hydrocarbons Using a Column Method

    Författare :Anja Enell; Avdelningen för kemiteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Kemiteknik och kemisk teknologi; Naturvetenskap; Chemical technology and engineering; Natural science; Miljöstudier; Environmental studies; coal tar; PAHs; desorption; soil; combustion residues; remediation; availability;

    Sammanfattning : Polycyclic aromatic hydrocarbons (PAHs) are a group of organic pollutants of great environmental concern, due to their toxicity, carcinogenicity and long persistence in the environment. To determine the potential risk associated with PAHs released from contaminated soil or waste materials, knowledge is required on the leachable concentrations of PAHs and the amounts available for release.

  4. 3. On the reaction mechanism for selective catalytic reduction of NOx by NH3 over Cu-zeolites

    Författare :Lin Chen; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; DFT; O2-activation; Cu-SSZ-13; NH3-SCR; Cu-CHA; Al-distribution;

    Sammanfattning : Nitrogen oxides (NOx) are major pollutants from combustion processes, being corrosive and hazardous to human health. The main technology for exhaust aftertreatment of NOx emitted from diesel engines is selective catalytic reduction with ammonia as reducing agent (NH3-SCR). LÄS MER

  5. 4. Computational studies of nickel catalysed reactions relevant for hydrocarbon gasification

    Författare :Abas Mohsenzadeh; Högskolan i Borås; []
    Nyckelord :DFT; H2O; CO; adsorption; dissociation; formyl; hydrocarbon combustion; hydrocarbon synthesis; water gas shift; gasification; Ni 111 ; Ni 110 ; Ni 100 ; Resursåtervinning; Resource Recovery;

    Sammanfattning : Sustainable energy sources are of great importance, and will become even more important in the future. Gasification of biomass is an important process for utilization of biomass, as a renewable energy carrier, to produce fuels and chemicals. LÄS MER

  7. 5. Towards Abatement of Selected Emissions from Metals Manufacturing

    Författare :Diana Orrling; Seshadri Seetharaman; S. Subramanian; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; mercury; zinc; iron; copper; sulfur dioxide; adsorption; pollution; spectroscopy; thermal desorption; polycrystalline; surfaces; Materials science; Teknisk materialvetenskap;

    Sammanfattning : Although the metallurgical industry has made great strides in the reduction of unwanted emissions to the atmosphere as a result of production processes, significant challenges still exist. From a global perspective, even large reductions in emissions per produced ton become immaterial when considering that the total world production of metals continues to increase. LÄS MER
