  2. 1. On Alternative Fuels for Internal Combustion Engines : A study of biodiesel, gaseous methane and methanol

    Author : Ludvig Adlercreutz; Andreas Cronhjort; Ola Stenlåås; Magnus Sjöberg; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Gaseous methane combustion; spark ignition; single cylinder research engine; particle number; particle emissions; oil ash content; CO2; Green House Gases; engine testing; engine development; emissions; combustion chamber design; injector fouling; environmental impact; road transportation; Machine Design; Maskinkonstruktion;

    Abstract :  This thesis covers some of the environmental impacts of internalcombustion engines running on alternative fuels. The focus of thestudies conveyed is the reduction of greenhouse gases and particleemissions, as these two factors are of great importance for the pathsthat road transportation is facing. READ MORE

  4. 2. Forests and Greenhouse gases. Fluxes of CO2, CH4 and N2O from drained forests on organic soils

    Author : Karin von Arnold; Leif Klemedtsson; Mats Nilsson; Björn Hånell; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Greenhouse gases; GHG; fluxes of CO2; CH4; drained forests; organic soils; Skogsbotanik; miljöaspekter; växthusgaser; Water in nature and society; Vatten i natur och samhälle;

    Abstract : One of the largest environmental threats believed to be facing us today is global warming due to the accumulation of green house gases (GHG). The concentrations of GHG in the atmosphere are a result of the net strength of different sinks and sources. READ MORE

  5. 3. Clean development Mechanism (CDM) Policy and Implementation in China

    Author : Lei Zeng; Leif Gustavsson; Mälardalens högskola; []
    Keywords : Climate change; Clean development mechanism; CDM; CO2; Green House Gas; GHG; landfill gas; sustainable development; China; Energi- och miljöteknik;

    Abstract : China is the second largest emitter of greenhouse gases (GHG) in the world. Since 68% of its primary energy is from coal, China’s average energy intensity is 7.5 times higher than the EU and 4.3 times higher than the US (EU, 2003). READ MORE

  6. 4. Innovative Contact Free Sensors for Metallurgical Process Control

    Author : Donald Malmberg; Stuart M. Millman; Högskolan i Halmstad; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; microwave spectroscopy; laser; TDLAS; high temperature; gas; slag; NATURAL SCIENCES; NATURVETENSKAP; spectroscopy; slag analysis; high temperatures; Mät- och instrumenteringsteknik; Instrumentation technology; TDLAS; microwave; laser; Fysicumarkivet A:2003:Malmberg;

    Abstract : The steel- and metal industry has an extensive production processing comprising many different process steps of solid, gaseous and liquid nature. Thus it is obvious that a number of different measurement technologies must be used to collect and evaluate key physical parameters which are necessary to control the production processes. READ MORE

  7. 5. Synthesis and modification of potential CO2 adsorbents : Amine modified silica and calcium carbonates

    Author : Baroz Aziz; Niklas Hedin; Lennart Bergström; Helmut Cölfen; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Amine-modified silica; carbon capture; Fractional factorial design; IR spectroscopy; calcium carbonate; Materials Chemistry; materialkemi;

    Abstract : The prospect of rapid changes to the climate due to global warming is subject of public concern. The need to reduce the emissions of atmospheric green house gases and in particular carbon dioxide is greater than ever. Extensive research is performed to find new solutions and new materials, which tackles this problem in economically benign way. READ MORE
