    Sammanfattning : Air pollution is a major concern in developed countries due to its hazardous health effects. Recent studies by the WHO (World Health Organization) estimate that urban air pollution causes a number of diseases of the respiratory tract and is associated with 150,000 deaths each year. LÄS MER

  3. 2. Study of Catalyst Deactivation in Three Different Industrial Processes

    Sammanfattning : Deactivation of catalysts were investigated focusing on three industrial processes: 1) Selective Catalytic Reduction (SCR) for abatement of NOx from biomass combustion using V2O5-WO3 /TiO2 catalysts; 2) Catalytic oxidation of volatile organic compounds (VOC) from printing industries using a Pt/γ-Al2O3 catalyst; and 3) Ni and Pt/Rh catalysts used in steam reforming reaction of bio-syngas obtained from biomass gasification.The aim has been to simulate industrial conditions in laboratory experiments in order to comprehend influence of compounds affecting catalysts performance.

    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Economics; Environmental economics; public good; public bad; negative externality; voluntary contribution; experiment; envionmental objectives; multiple emission reductions; sub-optimization; linear programming; multivariate stochastic control; emission trading; Nationalekonomi; Economics; Nationalekonomi; nationalekonomi; Economics;

    Sammanfattning : This dissertation consists of four self-contained essays.Essay IThis essay reports on an experimental study of how voluntary contributions in a public good game are affected by framing. In the public good context, average wealth improves from contributions. In the defensive contexts, the voluntary contributions prevent reductions in average wealth. LÄS MER
