  2. 1. Particle Emissions from Ships

    Author : Maria Zetterdahl; Chalmers University of Technology; []
    Keywords : NATURVETENSKAP; TEKNIK OCH TEKNOLOGIER; NATURAL SCIENCES; ENGINEERING AND TECHNOLOGY; LNG; marine fuel; fuel sulphur content; particle emission; sulphur emission control area; aromatics; SECA; heavy fuel oil; marine diesel oil; liquefied natural gas; ship emission;

    Abstract : Since 1st of January 2015 ships operating in sulphur emission control areas (SECAs) have to use marine fuels with a fuel sulphur content less than 0.1 %m/m. This regulation forces the ship owners to make a fuel shift and use low-sulphur marine fuel oils, use alternative fuels or use scrubbers on-board their ships. READ MORE

  4. 2. High-Temperature Corrosion Chemistry in Oxy-Fuel Combustion

    Author : Thomas Ekvall; Chalmers University of Technology; []
    Keywords : TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; ENGINEERING AND TECHNOLOGY;

    Abstract : Drastic cuts in global CO2 emissions are needed to mitigate the global warming if limiting global warming to 2ºC. The power generation sector is largely based on fossil fuels and produces a significant share of the global CO2 emissions. READ MORE

  5. 3. Selective Catalytic Reduction of NOx: Deactivation and Regeneration Studies and Kinetic Modelling of Deactivation

    Author : Raziyeh Khodayari; Institutionen för kemiteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Chemical technology and engineering; modelling; sulphation; regeneration; deactivation; bio fuel; WO3; V2O5; TiO2; catalyst; NOx; SCR; Kemiteknik och kemisk teknologi; Chemistry; Kemi;

    Abstract : Selective catalytic reduction of NOx (SCR) has been recognised as an effective post-combustion method for reducing nitrogen oxides from stationary sources. The cost of replacing the catalyst is a major part of the maintenance of the SCR system, hence it is desirable to advance methods to prolong the catalyst life. READ MORE

  6. 4. Energy Use, Efficiency Gains and Emission Abatement in Transitional Industrialised Economies: Poland and the Baltic States

    Author : Jürgen Salay; Miljö- och energisystem; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; implementation; sustainable energy; renewable energy; electricity production; power industry; Baltic states; Poland; transition; sulphur dioxide; air pollution; energy efficiency; Energy; energy use; Environmental technology; pollution control; Miljöteknik; kontroll av utsläpp; Energy research; Energiforskning;

    Abstract : This thesis is a study of how energy use and air pollution in Poland, Estonia, Latvia and Lithuania have been affected by the economic transition after 1989. It consists of six articles, which examine three different aspects of these changes. READ MORE

  7. 5. Methanation of biosyngas in a fluidized bed reactor

    Author : Martin Seemann; []
    Keywords : TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; ENGINEERING AND TECHNOLOGY; ENERGY TECHNOLOGY; REGENERATIVE ENERGIES; GASIFICATION OF WOOD; FLUIDIZED BED PROCESSES; CHEMICAL ENGINEERING; FUEL TECHNOLOGY; ALTERNATIVE ENERGIES; METHANATION OF HYDROGEN-CARBONMONOXIDE MIXTURES; SYNTHETIC FUELS; NATURAL GAS; BIOGASES;

    Abstract : Rising prices for fossil fuels and concerns over the climate change increase the interest in renewable energies. Synthetic natural gas (SNG) can be an option, filling the request for alternatives in the transportation sector, where the dependence on the oil is very strong. READ MORE
