  1. 1. Application of scattered sunlight spectroscopy for quantification of gas emissions from anthropogenic and natural sources

    Författare :Claudia Rivera; Chalmers University of Technology; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; anthropogenic sources; gas emission; volcanoes; sulphur dioxide; DOAS; nitrogen dioxide.; scattered sunlight spectroscopy; natural sources;

    Sammanfattning : Monitoring of gas emissions from natural and anthropogenic sources is of importance due to their negative effects on human health, atmospheric quality and ecosystems. Concern over air pollution has increased the need to develop measurement techniques suitable for gas flux determination. LÄS MER

  2. 2. Fundamental studies on the high temperature corrosion mechanisms of a 22Cr austenitic stainless steel in environments related to oxy-fuel combustion

    Författare :Luciana Intiso; Chalmers University of Technology; []
    Nyckelord :NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; NATURAL SCIENCES; EDX; TEM; KCl; Na2SO4; SEM; FIB; high temperature oxidation; sulphur dioxide; carbon dioxide; GI-XRD; stainless steels; water vapour; GDOES; t-EBSD;

    Sammanfattning : This thesis concern the high temperature corrosion mechanisms of stainless steels, with focus on a 22 wt.% Cr FeNiCr alloy (Sanicro 25), in environments related to oxy-fuel combustion, which is a promising technology that can provide enhanced CO2 recovery and sequestration from power plants by using post-combustion capture.

  3. 3. Remote Sensing of Forest Decline in the Czech Republic

    Författare :Jonas Ardö; Institutionen för naturgeografi och ekosystemvetenskap; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Czech Republic; neural networks; sulphur dioxide; air pollution; Norway spruce; deforestation; forest decline; GIS; spectral characteristics; Remote sensing; Landsat; Ore Mountains; Geology; physical geography; Geologi; fysisk geografi;

    Sammanfattning : This thesis describes the localisation and quantification of deforestation and forest damage in Norway spruce forests in northern Czech Republic using Landsat data. Severe defoliation increases the spectral reflectance in all wavelength bands, especially in the mid infrared region. LÄS MER

  4. 4. Energy Use, Efficiency Gains and Emission Abatement in Transitional Industrialised Economies: Poland and the Baltic States

    Författare :Jürgen Salay; Miljö- och energisystem; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; implementation; sustainable energy; renewable energy; electricity production; power industry; Baltic states; Poland; transition; sulphur dioxide; air pollution; energy efficiency; Energy; energy use; Environmental technology; pollution control; Miljöteknik; kontroll av utsläpp; Energy research; Energiforskning;

    Sammanfattning : This thesis is a study of how energy use and air pollution in Poland, Estonia, Latvia and Lithuania have been affected by the economic transition after 1989. It consists of six articles, which examine three different aspects of these changes. LÄS MER

  5. 5. Mixed metal oxide - noble metal catalysts for total oxidation of volatile organic compounds and carbon monoxide

    Författare :Magali Ferrandon; KTH; []
    Nyckelord :wood combustion; catalysts; total oxidation; manganese; copper; platinum; palladium; lanthanum; cerium; CO; VOC; methane; deactivation; thermal stability; sulphur dioxide;

    Sammanfattning : CO, volatile organic compounds, and polyaromatics areubiquitous air pollutants that give rise to deleterious healthand environmental effects. Such compounds are emitted, forinstance, by the combustion of wood, particularly fromsmall-scale heating appliances. LÄS MER
