  2. 1. Particle Characterization in the Exhaust Devices of Direct Injection Engines

    Author : Arun Prasath Karuppasamy; Anders Christiansen Erlandsson; Hanna Bernemyr; Alexander Bergmann; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Particle number; Particle size distribution; turbocharger; SCR; Exhaust after-treatment system; Particle dilution and conditioning; Partikelantal; storleksfördelning av partiklar; turboladdare; SCR; efterbehandlingssystem; avgasbehandlingssystem; partikelspädning och partikelanpassad mätmetod; Machine Design; Maskinkonstruktion;

    Abstract : Minimizing pollutants are of utmost importance to ensure sustainability in transportation. Particle emissions from internal combustion engines are especially harmful to human health, while also contributing to global warming. READ MORE

  4. 2. Volatility and number measurement of diesel engine exhaust particles

    Author : Hanna Bernemyr; Hans-Erik Ångström; Nigel Clark; KTH; []
    Keywords : particle emissions; measuring methods; particle number measurements; dilution; rotating disc diluter; v-TDMA; TECHNOLOGY; TEKNIKVETENSKAP;

    Abstract : Today, emission legislations for engine exhaust particles are mass based. The engines of today are low-emitting with respect to particle mass, with the emissions approaching the detection limit of the current measurement method. This calls for new and improved measurement methods. READ MORE

  5. 3. Benzene-char conversion and particle-vapor characterization in biomass gasification

    Author : Mario Morgalla; Michael Strand; Leteng Lin; Henrik Wiinikka; Linnéuniversitetet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; biomass gasification; fluidized bed; particulate matter; aerosol; char; tars; benzene conversion.; Bioenergiteknik Energi- och Miljöteknik; Bioenergy Technology;

    Abstract : Biomass is increasingly attracting attention as an alternative to fossil fuels. Gasification permits the thermochemical conversion of biomass into a product gas rich in carbon monoxide and hydrogen. The product gas can be further processed to generate heat, electricity, synthesis gas, chemicals, and biofuels. READ MORE

  6. 4. Alkali Metals and Tar in Biomass Thermochemical Conversion: Development and Application of Online Measurement Techniques

    Author : Dan Gall; Göteborgs universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Tar; Alkali Metals; Biomass; Thermochemical conversion; Online Measurements.;

    Abstract : Biomass is a renewable resource that can substitute the fossil-based products we depend on today. However, the conversion techniques require further improvement in order to be competitive with the traditional industry. READ MORE
