  1. 1. Biomass gasification in ABFB : Tar mitigation

    Författare :Nemanova Vera; Klas Engvall; Joan Salvadó; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Ash; biomass; char; gasification; iron-based; petcoke; tar; Chemical Engineering; Kemiteknik;

    Sammanfattning : Biomass gasification may be an attractive alternative for meeting future energy demand. Although gasification is a mature technology, it has yet to be fully commercialised due to tar formation. This study focuses on the tar mitigation in gas produced in an atmospheric bubbling fluidised bed (ABFB) gasification system. LÄS MER

  3. 2. Climate change mitigation in China

    Författare :Bo Xu; Ronald Wennersten; Kerstin Kuchta; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; China; Climate change mitigation; Environmental Kuznets Curve EKC hypothesis; Mitigation target; Business-as-usual BAU scenarios; Policy instruments;

    Sammanfattning : China has been experiencing great economic development and fast urbanisation since its reforms and opening-up policy in 1978. However, these changes are reliant on consumption of primary energy, especially coal, characterised by high pollution and low efficiency. LÄS MER

  4. 3. Promises and Pitfalls of Bioenergy with Carbon Capture and Storage : Actors' Perspectives, Challenges, and Mitigation Deterrence in Sweden

    Författare :Emily Rodriguez; Anders Hansson; Simon Haikola; Stefan Grönkvist; Nils Markusson; Linköpings universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Bioenergy with carbon capture and storage BECCS ; Negative emission technologies NETs ; Carbon dioxide removal CDR ; Sustainability transitions; Mitigation deterrence; Sweden; Bioenergi med koldioxidavskiljning och lagring bio-CCS ; Negativa utsläpp; Koldioxidinfångningsmetoder; Energiomställningen; Mitigation deterrence; Sverige;

    Sammanfattning : Carbon dioxide removal (CDR) methods, such as bioenergy with carbon capture and storage (BECCS), have gained traction in international climate policy arenas to meet net-zero goals. Even though companies operating facilities with large point sources of biogenic emissions, such as pulp and paper industries and energy utilities, could implement carbon capture, there are few studies that take a bottomup perspective to study these key actors.

  5. 4. Plastic Shrinkage Cracking In Concrete : Mitigation and Modelling

    Författare :Faez Sayahi; Mats Emborg; Andrzej Cwirzen; Hans Hedlund; Pietro Lura; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Structural Engineering; Konstruktionsteknik;

    Sammanfattning : Early-age (up to 24 hours after casting) cracking may become problematic in any concrete structure. It can have a negative influence on the aesthetics of the concrete structure, as well as decreasing the durability and serviceability by facilitating the ingress of harmful materials into the concrete bulk.

  7. 5. Nonlinearity mitigation in phase-sensitively amplified optical transmission links

    Författare :Kovendhan Vijayan; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; copier-PSA; nonlinearity mitigation; phase-sensitive amplifier; self-phase modulation mitigation; low-noise amplification; optical transmission; crossphase modulation mitigation;

    Sammanfattning : The fundamental limitations in fiber-optic communication are caused by optical amplifier noise and the nonlinear response of the optical fibers. The quantum-limited noise figure of erbium-doped fiber amplifier (EDFA) or any phase-insensitive amplifier is 3 dB. LÄS MER
