  2. 11. Enhanced Catalytic Pyrolysis of Biomass for High-Quality Biofuel Production

    Author : Devy Kartika Ratnasari; Weihong Yang; Pär Jönsson; Tobias Richards; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Al-MCM-41; lignocellulose biomass; H-ZSM-5; kinetic study; catalyst regeneration;

    Abstract : The rapid increase in energy demand, the extensive use of fossil fuels, and the urgent need to reduce carbon dioxide emissions have raised concerns in the transportation sector, since transportation has been primarily dependent on fossil fuels. Biofuel from biomass can make significant contributions to overcome the expected depletion of fossil fuels and reduce carbon emissions. READ MORE

    Abstract : During the last decades, image analysis has become an important tool in various applications. The increase in computer power has led to that more advances algorithms can be developed. READ MORE

  5. 13. Sound quality evaluation of heavy-duty engines in free field conditions

    Author : Md. Shafiquzzaman Kahn; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Teknisk akustik; Engineering Acoustics;

    Abstract : Annoyance response to vehicle noise is commonly reported. The impact reduction measures must therefore be measured scientifically. A scientific system for describing and defining annoyance is therefore required. There is furthermore a need to reduce the annoying components of the sound of vehicles. READ MORE

    Abstract : The transition to a bioeconomy, in which resources from biowaste could be reclaimed for the production of chemicals, materials or fuels, could contribute to the establishment of a sustainable society by replacing fossil fuels as raw materials. The core of this bioeconomy would be biorefineries, which are similar to petroleum-based refineries, but are facilities where biowaste is processed and refined through different chemical and/or biochemical processes.
