4. 23. Ash transformation in thermochemical conversion of different biomass resources with special focus on phosphorus

   Författare :Ali Hedayati; Marcus Öhman; Christoffer Boman; Kentaro Umeki; Anita Pettersson; Luleå tekniska universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; agricultural biomass; forest residues; sewage sludge; ash transformation; release; potassium; phosphorus; combustion; gasification; bio charcoal; phosphorus recovery; Energy Engineering; Energiteknik;

   Sammanfattning : A great potential exists for increasing the use of bioenergy in thermochemical processes by utilizing agricultural biomass, forest residues, and sewage sludge that have high availability. Many of these biomass assortments have high ash contents with relatively high concentrations of ash-forming elements such as potassium (K), calcium (Ca), silicon (Si), and phosphorus (P). LÄS MER

5. 24. A co-simulation based framework for the analysis of integrated urban energy systems : Lessons from a Swedish case study

   Författare :Monica Arnaudo; Björn Laumert; Monika Topel; Louise Ödlund; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energy Technology; Energiteknik;

   Sammanfattning : As major responsible for CO2 emissions, the energy sector is urgently called to take action against climatechange. The integration of renewable energy resources is a solution that, however, comes with a challenge.In fact, renewables are often variable, unpredictable and distributed. LÄS MER

7. 25. Black liquor gasification : experimental stability studies of smelt components and refractory lining

   Författare :Mathias Råberg; Dan Boström; Anders Nordin; Honghi Tran; Umeå universitet; []
