  1. 1. Determination of VOC Emissions from Surface Coatings by Environmental Test Chamber Measurements

    Author : Alireza Afshari; Chalmers University of Technology; []
    Keywords : chamber; surface coating; emission rate; measurement; VOC; concentration;

    Abstract : The emitting properties of different building materials are obtained by measurements in environmental chambers of a few established designs. In order to interpret the results from the measurements and to predict the influence on the indoor environment, it is necessary to have a good understanding of the parameters governing the emission process.

  2. 2. Catalytic Incineration of CO and VOC Emissions over Supported Metal Oxide Catalysts

    Author : Per-Olof Larsson; Tillämpad biokemi; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Titania; Ceria; Manganese oxide; Copper oxide; VOC; CO; Ethanol; Ethyl acetate; Metal oxide catalysts; Catalytic combustion; Catalytic incineration; Alumina.; Chemical technology and engineering; Kemiteknik och kemisk teknologi; Fysicumarkivet A:1999:Larsson;

    Abstract : Catalytic incineration is one of the methods to reduce the emissions of CO and VOCs. Low operation temperature and low catalyst cost are essential parameters for catalytic incinerators. Pt/Al2O3 catalysts are frequently used today, but the cheaper metal oxide catalysts can be very competitive if comparable overall activity is obtained. READ MORE

  3. 3. Atmospheric Chemistry of Volatile Organic Compounds: Oxidation Products, Mechanisms and Secondary Organic Aerosol Formation

    Author : Julia Hammes; Göteborgs universitet; Göteborgs universitet; Gothenburg University; []
    Keywords : SOA; VOC; anthropogenic; biogenic; FIGAERO; CIMS; HOMs; ELVOCs; atmospheric oxidation; chemical mechanism; NOx; limonene; a-pinene; TMB; ozone; nitrate; OH; radical chemistry; RO2; G-FROST; GO:PAM;

    Abstract : The results from this work are a piece in understanding the complex puzzle of atmospheric aerosol formation. Secondary organic aerosol (SOA) formed by the oxidation of volatile organic compounds (VOC) in the atmosphere is a key component of air pollution with a strong negative impact on human health and influence on climate, but its formation is poorly understood.

  4. 4. Optical remote sensing of industrial gas emission fluxes

    Author : John Johansson; Chalmers University of Technology; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; optical remote sensing; DOAS; gas emission; absorption spectroscopy; VOC; flux measurement; solar occultation; FTIR; formaldehyde;

    Abstract : Mobile optical remote sensing techniques offer promising possibilities to quantify and geographically attribute local industrial gaseous emissions to the atmosphere. Studies have repeatedly shown that such emissions are often poorly understood, underestimated, and thereby not properly accounted for in emission inventories and regional atmospheric chemistry models, especially for emissions of VOCs.

  5. 5. Secondary Emissions from Concrete Floors with Bonded Flooring Materials - Effects of Alkaline Hydrolysis and Stored Decomposition Products

    Author : Anders Sjöberg; Chalmers University of Technology; []
    Keywords : OCIC; secondary emission; moisture; adhesive; IAQ; decomposition products; floorings; concrete; VOC; building materials;

    Abstract : It has been demonstrated before that the presence of VOC lowers the quality of indoor air. There are also several indications that certain organic compounds in indoor air (OCIA) can give rise to sick building syndrome (SBS). READ MORE
