  1. 21. A Study of Propane and Propene Ammoxidation over Antimony-Vanadium-Oxide Catalysts at Steady-State and Transient Conditions

    Författare :Roland Nilsson; Avdelningen för kemiteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Kemiteknik och kemisk teknologi; Chemical technology and engineering; oxidation; Ammoxidation; propane; propene; propylene; catalysis; transient response; antimony vanadium oxides;

    Sammanfattning : Propane ammoxidation catalysts of differing Sb/V ratio and consisting of differing amounts of the V2O5, alpha-Sb2O4, and Sb0.92V0.92O4 phases were prepared. In the first paper, the structure of Sb0. LÄS MER

  3. 22. Willingness to Pay for a Reduction in Road Mortality Risk: Evidence from Sweden

    Författare :Henrik Andersson; Nationalekonomiska institutionen; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Willingness to Pay; Value of a Statistical Life; Revealed preferences; Stated preferences; economic systems; economic theory; econometrics; Economics; ekonomisk teori; ekonometri; ekonomisk politik; ekonomiska system; economic policy; Nationalekonomi; Road-mortality risk;

    Sammanfattning : The thesis consists of an introductory chapter, followed by three chapters in which willingness to pay (WTP) for a reduction in car- and road-mortality risk is estimated using both revealed- and stated-preference methods. In chapter 2 the hedonic regression technique is used to estimate the value of traffic safety, using information from the Swedish market for automobiles. LÄS MER

  4. 23. Analysis of a novel Transversal Flux Machine with a tubular cross-section for Free Piston Energy Converter application

    Författare :Alija Cosic; Chandur Sadarangani; Nicola Bianchi; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electronic measurement and instrumentation; Elektronisk mät- och apparatteknik;

    Sammanfattning : Constantly growing need for oil, all over the world, has caused oil price to rise rapidly during the last decade. High oil prices have made fuel economy as one of the most important factors when consumers are buying their cars today. LÄS MER

  5. 24. Urban driving patterns - characterisation, variability and environmental implications

    Författare :Eva Ericsson; Trafik och väg; []

    Sammanfattning : Driving patterns, i.e. the speed and acceleration profiles of vehicles affect exhaust emission and fuel consumption considerably. LÄS MER

  7. 25. Catalytic Reduction of NOx on Heavy-Duty Trucks

    Författare :Christian Künkel; Avdelningen för kemiteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Kemiteknik och kemisk teknologi; Chemical technology and engineering; real time; strategy; model; catalysis; exhaust gas; diesel; automotive; deNOx; NOx reduction; NOx storage; HC-SCR; Carbochemistry; petrochemistry; fuels and explosives technology; Petrokemi; bränslen; sprängämnen;

    Sammanfattning : The objective of the work described in this thesis is to identify the principles and parts of an aftertreatment system for the catalytic NOx reduction for heavy-duty diesel vehicles, and to demonstrate such a system in full-scale. The reducing agent is diesel fuel. LÄS MER
