  1. 1. Renewable gas in a Swedish context

    Detta är en avhandling från Department of Chemical Engineering, Lund University

    Författare :Laura Malek; Lunds universitet.; Lund University.; [2018-09-18]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; synthetic natural gas; biomass; gasification; gas grid; techno-economic; tar; ammonia;

    Sammanfattning : In order to increase the use of sustainable energy in Sweden, it is necessary to substitute fossil energy carriers with renewable counterparts. Synthetic natural gas (SNG) produced from renewable resources via biomass gasification and methanation could replace a proportion of the natural gas used in Sweden. LÄS MER

  2. 2. Long-term properties of polyethylene films efficiency of a natural antioxidant

    Detta är en avhandling från Stockholm : KTH

    Författare :Clara Strandberg; KTH.; [2006]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Polymer Technology; alfa-tocopherol; Polyethylene PE ; Thermal aging; Infrared Spectroscopy FT-IR ; Chemiluminescence CL ; Solid-phase microextraction SPME ; NATURAL SCIENCES Chemistry; NATURVETENSKAP Kemi;

    Sammanfattning : There is a growing awareness of the risks of pollution in biological systems and one potential problem is the synthetic antioxidants, used for e.g. the stabilisation of polymeric materials. Natural antioxidants are an interesting alternative, if the high efficiency and thermal stability of the synthetic compounds can be reached. LÄS MER

  3. 3. Process Integration Opportunities for Synthetic Natural Gas (SNG) Production by Thermal Gasification of Biomass

    Detta är en avhandling från Stockholm : KTH

    Författare :Stefan Heyne; [2010]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; biomass; synthetic natural gas; energy systems; process integration; renewable energy;

    Sammanfattning : Synthetic natural gas (SNG) from gasified biomass is one promising option to produce renewable transport fuels. This thesis presents a process integration study investigating thermal gasification of biomass for the production of SNG and identifies critical conversion steps for the overall process performance.

  4. 4. Catalytic tar cleaning of biomass-derived gas with simultaneous catalyst regeneration

    Detta är en avhandling från ; Chalmers tekniska högskola; Gothenburg

    Författare :Fredrik Lind; [2011]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Tar cleaning; Catalytic gas cleaning; Biomass gasification;

    Sammanfattning : Tar cleaning of raw gas from biomass gasification is a necessary operation before the gas can be used as feedstock for synthetic fuels. The technology for gas cleaning that is commercially available today (scrubber systems), is associated with problems like heat penalties and loss of the chemically stored energy within the tars.

  5. 5. Synthesis and spectroscopic characterization of emerging synthetic cannabinoids and cathinones

    Detta är en avhandling från Linköping : Linköping University Electronic Press

    Författare :Andreas Carlsson; Linköpings universitet.; Linköpings universitet.; [2016]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : The application of different analytical techniques is fundamental in forensic drug analysis. In the wake of the occurrence of large numbers of new psychoactive substances possessing similar chemical structures as already known ones, focus has been placed on applied criteria for their univocal identification.
