  2. 12. Chemical and Morphological Characterisation of Aerosol Particles in the Tropopause Region

    Author : Hung Nguyen Ngoc; Kärnfysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; CARIBIC; Physics; Singel particle analysis TEM and EFTEM; Carbon and Sulphur; Light element analysis; Aerosol sampler; Chemical Characterisation; Aerosol in the Tropopause Region; Nuclear physics; Technological sciences; Fysik; Teknik; Kärnfysik; Fysicumarkivet A:000;

    Abstract : The aim of this work was to study atmospheric aerosols, focusing on the chemical composition, the morphology and the origin of the aerosol in the upper troposphere and lowermost stratosphere. An aerosol sampler was developed for this purpose. A new method for quantitative analysis of the major components of the aerosol, i.e. READ MORE

  3. 13. Development of a regeneration procedure for commercial automotive three-wy catalysts

    Author : Henrik Birgersson; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; deactivation; fouling; sintering; poisoning; palladium; rhodium; regeneration; dispersion; thermal gas treatment; oxy-chlorine; TWC; automotive catalyst; Chemical process equipment; Kemisk apparatteknik;

    Abstract : Car exhaust catalysts were introduced in the early 1980’s, to limit the release of pollutants such as hydrocarbons, carbon monoxides and nitrogen oxides. These catalysts contain noble metals such as palladium (Pd), platinum (Pt) and rhodium (Rh) and are able to simultaneously abate all three of the above-mentioned pollutants, hence the name three-way catalyst (TWC).

  4. 14. Policy induced technological change : Productivity and innovation effects in biomass-using industry and energy generation

    Author : Johan Brolund; Magnus Lindmark; Luleå tekniska universitet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Economics; Nationalekonomi;

    Abstract : The main objective of this thesis is to investigate the impact of public environmental policy on technological change in the biomass-using industry and energy generation. The thesis contains an introductory part followed by the empirical investigation which is divided into two self-contained articles. READ MORE

  5. 15. Generation of synthesis gas for fuels and chemicals production

    Author : Per Tunå; Avdelningen för kemiteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Synthetic fuels and chemicals; gasification; gas conditioning; simulation; tar-cracking;

    Abstract : Many scientists believe that the oil production will peak in the near future, if the peak has not already occurred. Peak oil theories and uncertain future oil deliveries have stimulated interest in alternative sources of fuel and chemicals. READ MORE
