  1. 1. ELM: Environmental Assessment of Fuel Supply Systems for Vehicle Fleets

    Författare :Magnus Blinge; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; exergy; biomass; alternative motor fuel; wnvironment; transportation; renewable; energy; Life Cycle Assessment; logistics; emission;

    Sammanfattning : This thesis is based on the idea of applying a logistics approach to fuel supply systems. The complete supply chain from energy raw material to end use in the vehicle is analysed while keeping track of energy conversion efficiency, exergy consumption and emissions to air. LÄS MER

  3. 2. Characterization of the Combustion of Light Alcohols in CI Engines : Performance, Combustion Characteristics and Emissions

    Författare :Sam Shamun; Förbränningsmotorer; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Methanol; Ethanol; Oxygenated Fuel Blends; Compression Ignition Engine; Partially Premixed Combustion; Combustion Characteristics; Efficiency; Emissions; Particulate Matter; Metanol; Etanl; Oxygenerade Bränsleblandningar; Kompressionsantänd Motor; Partiellt Förblandad Förbränning; Förbränningsegenskaper; Verkningsgrad; Emissioner; Partiklar;

    Sammanfattning : Alternative fuels for combustion engines are becoming increasingly popular as society is pushing to phase out fossil energy to reduce CO2 emissions. The compression ignition (CI) engine has a high overall efficiency which makes it a valuable option for the transport fleet, despite the well known NOx and soot pollutants it emits. LÄS MER

  4. 3. Black Liquor Gasification-Based Biorefineries – Determining Factors for Economic Performance and CO2 Emission Balances

    Författare :Karin Pettersson; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; biorefineries; system expansion; second generation biofuels; black liquor gasification; kraft pulp and paper mill; global CO2 emissions; heat integration; energy market scenarios;

    Sammanfattning : Biorefineries constitute an attractive future development option for the pulp and paper industry, allowing mills to produce not only pulp or paper but also other value-added products. Black liquor gasification (BLG) is currently being developed as an alternative technology for energy and chemical recovery in kraft pulp and paper mills. LÄS MER

  5. 4. Micro- and Nanostructures for Studies of Model Biological Systems

    Författare :Cassandra Niman; Fasta tillståndets fysik; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Fysicumarkivet A:2014:Niman;

    Sammanfattning : Sub-cellular biological components are complex systems that work together to control and maintain cellular activity and health. It is useful to study the basic elements that constitute the sub-cellular components using model systems, which mimic certain parts of the overall system, in order to better understand the system as a whole.

  7. 5. A trinity of sense : Using biomass in the transport sector for climate change mitigation

    Författare :Erik G. Lindfeldt; Mats Westermark; Lars J. Nilsson; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Biofuel; biomass; carbon dioxide capture and storage; energy systems; ethanol; hybrid cycle; mixed conducting membrane reactor; pressurized fluidized bed combustion; Sweden; transport; Chemical engineering; Kemiteknik;

    Sammanfattning : This thesis analyses two strategies for decreasing anthropogenic carbon dioxide (CO2) emissions: to capture and store CO2, and to increase the use of biomass. First, two concepts for CO2 capture with low capture penalties are evaluated. LÄS MER
