    Abstract : There is a consensus worldwide that the share of renewable energy sources should be increased to mitigate climate change. The strive to increase the renewable energy fraction can partly be met by an increased utilization of different biomass feedstocks. READ MORE

  5. 3. Thermochemical behavior of pretreated biomass

    Author : Amit Kumar Biswas; Weihong Yang; Wlodzimierz Blasiak; Henrik Kusar; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Biomass; Pretreatment; therochemical conversion; pyrolysis; combustion; SRA - Energy; SRA - Energi; Energy Engineering;

    Abstract : Mankind has to provide a sustainable alternative to its energy related problems. Bioenergy is considered as one of the potential renewable energy resources and as a result bioenergy market is also expected to grow dramatically in future. However, logistic issues are of serious concern while considering biomass as an alternative to fossil fuel. READ MORE

  6. 4. Combustion of gasified biomass: : Experimental investigation on laminar flame speed, lean blowoff limit and emission levels

    Author : Nur Farizan Binti Munajat; Torsten Fransson; Catharina Erlich; Jens Klingmann; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; biomass gasification; gasified biomass; laminar flame speed; blowoff; emissions;

    Abstract : Biomass is among the primary alternative energy sources that supplements the fossil fuels to meet today’s energy demand. Gasification is an efficient and environmental friendly technology for converting the energy content in the biomass into a combustible gas mixture, which can be used in various applications.
