  1. 1. Fischer-Tropsch and FAME Fuels as Alternatives for Diesel Engines; an Experimental Study

    Författare :Monica Johansson; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Emissions; SME; Fischer-Tropsch; NOx; Combustion; Alternative fuels; Soot; Biodiesel; RME; FAME; GTL; PME;

    Sammanfattning : Research into alternative fuels is necessitated by our heavy reliance on limited oil reserves and increasingly strict emissions legislation. The studies reported in this thesis involved conducting engine tests using alternatives to fossil Diesel fuel in both heavy-duty and light-duty single cylinder engines. LÄS MER

  3. 2. Ryktbarhetens ansikte : Verner von Heidenstam, medierna och personkulten i sekelskiftets Sverige

    Författare :Andreas Nyblom; Martin Kylhammar; Lisbeth Larsson; Linköpings universitet; []
    Nyckelord :Media history; sociology of literature; public discourse; celebrity culture; cultural production; Verner von Heidenstam; 19th century; 20th century; Sweden; Kulturhistorisk medieforskning; litteraturhistoria; litteratursociologi; kändisskap; celebritetskultur; mediebilder; reception; historiebruk; offentlig meningsproduktion; Verner von Heidenstam; sekelskiftet 1900; HUMANITIES and RELIGION; HUMANIORA och RELIGIONSVETENSKAP;

    Sammanfattning : Ryktbarhetens ansikte behandlar en tidigare outforskad aspekt av svensk litteraturoch kulturhistoria: författaren som celebritet. Kändisskap är ingen senmodern företeelse kopplad till uppkomsten av medieformer som film eller television. LÄS MER

  4. 3. Deactivation of SCR catalysts - Impact of sulfur and the use of biofuels

    Författare :Johanna Englund; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Cu-SSZ-13; Cu-CHA; Catalyst deactivation; Activity test; DeNOx; Sulfur; NOx reduction; NH3-SCR; FAME; Emission control; HVO; Vanadia; Biofuel;

    Sammanfattning : In a near future, limits on CO2 emissions from vehicles will be introduced, which requires development of more fuel-efficient engines and most likely a transition towards the use of more biofuels. With the implementation of biofuels several issues could arise, one being the lack of fuel standards for these new type of fuels, leading to higher concentrations of catalyst poisons compared to conventional fossil fuels.

  5. 4. Effects of trace elements in biodiesel on the performance of diesel oxidation catalysts in heavy-duty vehicles

    Författare :Jonas Granestrand; Lars Pettersson; Todd J. Toops; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Diesel Oxidation catalyst; heavy-duty vehicles; catalyst deactivation; biodiesel; NAP-XPS; XANES; Phosphorus; alkali metals; Pt Pd Al2O3; Chemical Engineering; Kemiteknik;

    Sammanfattning : To reduce net greenhouse gas emissions, a shift towards adoption of biofuels is ongoing in the transport sector. Heavy-duty diesel vehicles are equipped with aftertreatment equipment, comprising of catalysts and filters, and how this equipment is affected by the use of biofuels is not yet fully understood.

  7. 5. Thermally cured coil-coatings utilizing novel resins and fatty acid methyl esters as reactive diluents

    Författare :Katarina Johansson; Mats Johansson; Rolf van Benthem; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Coatings; Coil-coatings; Thermal cure; Reactive diluents; Fatty acids; Transesterification; Hyperbranched polyester resins; Film properties; Polymer chemistry; Polymerkemi;

    Sammanfattning : Solvent-borne thermally cured coil-coating resins contain large amounts of volatile organic solvents in order to obtain suitable flow for film application. This work describes how the expensive and environmental hazardous volatile organic solvent content of a solvent-borne thermally cured polyester/melamine coil-coating system can be reduced by introduction of fatty acid methyl esters (FAMEs) as reactive diluents and modification of the polyester binder resin.
