  2. 6. The Character of the Particle Emissions from Possible Future Marine Fuels in SOx ECAs

    Author : Maria Anderson; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; heavy fuel oil; emission factor; marine fuel; black carbon; marine diesel oil; LNG; ship emission; liquefied natural gas; nanoparticle;

    Abstract : Particles in the ambient air come from both natural and anthropogenic sources. One anthropogenic source is combustion of fossil fuels. The awareness of these particles impact on human health and climate has increased the interest for the particle emissions from e.g. READ MORE

  4. 7. Reduction of the N2O Emission from Fluidized Bed Combustion by Afterburning

    Author : Lennart Gustavsson; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; chemical modelling; fuel injection; nitrous oxide; fluidized bed combustion; fluidized beds; afterburning; homogeneous heterogeneous reactions; N2O reduction; fluidized bed boiler; N2O emissions;

    Abstract : A method for reducing N2O emissions from fluidized bed combustion is presented and investigated. In contrast to flame combustion, fluidized bed combustion generates significant amounts of nitrous oxide (N2O) which are emitted to the atmosphere. READ MORE

  5. 8. Elements of the Asia Pacific gas market : market power and efficiency

    Author : Bo Jonsson; Luleå tekniska universitet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Economics; Nationalekonomi;

    Abstract : Natural gas trade in the Asian Pacific market is heavily dependent on the demand from Japan, which imports around 75% of the gas traded as LNG (liquefied natural gas) in the region. This study argues that the buyers in Japan, through cooperation have the potential to exert the market power that their large market share provides them with. READ MORE

    Abstract : IPCC reported in its climate change report 2013 that the atmospheric concentrations of the greenhouse gases (GHG) carbon dioxide (CO2), methane, and nitrous oxide now have reached the highest levels in the past 800,000 years. CO2 concentration has increased by 40% since pre-industrial times and the primary source is fossil fuel combustion. READ MORE

  7. 10. Essays on energy demand and renewable natural resource management

    Author : Justice Tei Mensah; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES;

    Abstract : This thesis is a collection of five self-contained papers in the area of energy demand and renewable natural resource management. Paper 1 analyzes the dynamics in cooking fuel choices among Ghanaian households over the period 2005 and 2013 and further investigate the main forces driving households’ choice of cooking fuel.
