  1. 6. Assessing the Integration of Biomass Gasification-Based Production of Chemicals — Case Study of an Oxo Synthesis Plant

    Författare :Maria Arvidsson; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; chemicals production; biorefinery; gasification; syngas; oxo synthesis; process integration;

    Sammanfattning : The chemical industry sector is energy-intensive and highly dependent on fossil feedstock. The primary long-term option to reduce fossil feedstock dependence and greenhouse gas (GHG) emissions is to switch to renewable feedstock. LÄS MER

  3. 7. Fischer-Tropsch Synthesis over Cobalt-based Catalysts for BTL applications

    Författare :Matteo Lualdi; Christofer Leygraf; Roy Johnsen; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; cobalt; Fischer-Tropsch; syngas; selectivity;

    Sammanfattning : Fischer-Tropsch synthesis is a commercial technology that allows converting synthesis gas, a mixture of CO and H2, into fuels and chemicals. This process could be one of the actors in the reduction of oil dependency of the transportation sector. LÄS MER

  4. 8. Application of Laser-based Diagnostics to a Prototype Gas Turbine Burner at Selected Pressures

    Författare :Ronald Whiddon; Förbränningsfysik; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; OH; Laser Diagnostics; Elevated Pressure; Syngas; DLE; NOx; Combustion; Gas Turbine; PIV; PLIF; Pilot; SGT-750; Fysicumarkivet A:2014:Whiddon;

    Sammanfattning : The matured laser-diagnostic techniques of planar laser-induced fluorescence (PLIF) and particle image velocimetry (PIV) were applied to a prototype gas turbine burner operating on various fuels. The work was performed to provide verification of computational fluid dynamic (CFD) models of the combustion of atypical fuels in a gas turbine combustor. LÄS MER

  5. 9. Development of Catalytic Nanomaterials for Three Industrial Processes

    Författare :Stylianos Nassos; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Fischer-Tropsch; nanotechnology; selective catalytic oxidation of ammonia; hydrogen production; CO2 capture; microemulsion; nanoparticles; activity; syngas; gasified biomass;

    Sammanfattning : Nanotechnology is a relatively new research topic that attracts increasing interest from scientists and engineers all over the world, due to its novel applications. The use of nanomaterials has extended to a broad range of applications, for example chemical synthesis, catalytic combustion and microporous media synthesis, contributing to achievement of improved or promising results.

  7. 10. Alkali-enhanced gasification of biomass : laboratory-scale experimental studies

    Författare :Albert Bach-Oller; Kentaro Umeki; Viktor Scherer; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; alkali; biomass; gasification; tar; soot; potassium; char; syngas; enhanced; Energiteknik; Energy Engineering;

    Sammanfattning : Gasification seeks to break carbonaceous materials into synthetic gas (CO+H2) which can be subsequently upgraded into valuable products. Thus gasification can be utilized to convert low grade biomass stocks into carbon-neutral chemicals heat and power. LÄS MER
