  1. 1. Large-Scale Production and Use of Biomethane

    Detta är en avhandling från Gothenburg : Chalmers tekniska högskola

    Författare :Alberto Alamia; [2016]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; dual fuel; Biomass gasification; SNG; power-to-gas; well-to-wheel; biomethane; biorefinery; GoBiGas; DFB gasifier; process simulation;

    Sammanfattning : Societal ambitions to create an economy based on renewable resources, require the development of technologies transforming these resources into energy-carrying products and biomaterials. Dual fluidized bed (DFB) gasification represents a key technology for achieving sustainability targets, as it is a scalable and highly efficient route for the conversion of biomass. LÄS MER

  2. 2. Large-Scale Graphene Production for Environmentally Friendly and Low-Cost Energy Storage Production, Coating, and Applications

    Detta är en avhandling från Sundsvall : Mid Sweden University

    Författare :Nicklas Blomquist; Håkan Olin; Renyun Zhang; Christina Dahlström; Patrik Johansson; [2019]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Graphene; Energy storage; Supercapacitors; EDLC;

    Sammanfattning : There is great demand for energy-efficient, environmentally sustainable, and cost-effective electrical energy storage devices. One important aspect of this demand is the need for automotive electrification to achieve more energy-efficient transportation at a reasonable cost, thus supporting a fossil-fuel free society.

  3. 3. Large-scale Bioreactor Phenomena and Characteristics; Effects on E.coli fed batch fermentations on 30m3 scale

    Detta är en avhandling från Stockholm : Bioteknologi

    Författare :Gustav Silfversparre; [2002]
    Nyckelord :Large-scale; E.coli; fed batch; concentration gradients; mixing;

    Sammanfattning : Due to economical and practical limitations the fluiddynamics and mass transport properties are less optimal inlarge-scale bioreactors compared to lab-scale bioreactors. Incombination with the microbial reaction rates this creates amuch more dynamic environment for cells cultivated inlarge-scale bioreactors compared to lab-scale bioreactors. LÄS MER

  4. 4. Low-Cost, Environmentally Friendly Electric Double-Layer Capacitors Concept, Materials and Production

    Detta är en avhandling från Sundsvall : Mid Sweden University

    Författare :Britta Andres; Håkan Olin; Christina Dahlström; Jonas Örtegren; Renyun Zhang; [2017]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Electric Double-Layer Capacitor; Graphite; Cellulose Nanofibers; Large-Scale; Mass Balancing; Metal-Free;

    Sammanfattning : Today’s society is currently performing an exit from fossilfuel energy sources. The change to sustainable alternativesrequires inexpensive and environmentally friendly energy storagedevices. However, most current devices contain expensive,rare or toxic materials. These materials must be replaced bylow-cost, abundant, nontoxic components. LÄS MER

  5. 5. Flow Over Large-Scale Naturally Rough Surfaces

    Detta är en avhandling från Luleå

    Författare :Robin Andersson; [2016]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Strömningslära; Fluid Mechanics;

    Sammanfattning : The fluid mechanical field of rough surface flows has been developed ever since the first experiments by Haagen (1854) and Darcy (1857). Although old, the area still holds merit and a surprising amount of information have to this day yet to be fully understood, which surely is a proof of its complexity. LÄS MER
