2. 21. Gasification and Pyrolysis Characterization and Heat Transfer Phenomena During Thermal Conversion of Municipal Solid Waste

   Author : Chunguang Zhou; Weihong Yang; Wlodzimierz Blasiak; Petr Stehlik; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; municipal solid waste; pyrolysis; gasification; heat transfer; CaO; CO2; reforming; numerical model; Energy Technology; Energiteknik; Chemical Engineering; Kemiteknik;

   Abstract : The significant generation of municipal solid waste (MSW) has become a controversial global issue. Pyrolysis and gasification technologies for treating rejects from solid waste disposal sites (SWDSs), for which over 50 % of MSW is attributed to combustible species, have attracted considerable attention.

4. 22. Fate of phthalic acid esters during digestion of municipal solid waste under landfill conditions

   Author : Jörgen Ejlertsson; Linköpings universitet; []
   Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; INTERDISCIPLINARY RESEARCH AREAS; TVÄRVETENSKAPLIGA FORSKNINGSOMRÅDEN;

   Abstract : The objective of this thesis has been to investigate whether anaerobic microorganisms developing in acidogenic and methanogenic landfill environments have the potential to degrade phthalic acid esters (PAEs) and what kinds of intermediates may be formed, assuming PAE degradation. PAEs form a group of compounds widely used in huge amounts worldwide, mainly as plasticiser in PVC-plastics. READ MORE

5. 23. Iron-based materials as tar cracking catalyst in waste gasification

   Author : Thomas Nordgreen; Krister Sjöström; Truls Liliedahl; Rainer Reimert; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Chemical engineering; Kemiteknik;

   Abstract : The treatment of municipal solid waste (MSW) in Sweden has changed during the past decades due to national legislation and European Union directives. The former landfills have more or less been abandoned in favour of material recycling and waste incineration. On a yearly basis approximately 2. READ MORE

6. 24. Mathematical modeling of municipal solid waste plasma gasification in a fixed-bed melting reactor

   Author : Qinglin Zhang; Weihong Yang; Wlodzimierz Blasiak; Halina Kruczek; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Mathematical modeling; plasma gasification; municipal solid waste; fixed-bed;

   Abstract : The increasing yield of municipal solid waste (MSW) is one of the main by-products of modern society. Among various MSW treatment methods, plasma gasification in a fixed-bed melting reactor (PGM) is a new technology, which may provide an efficient and environmental friendly solution for problems related to MSW disposals.

7. 25. Polygeneration District Heating and Cooling Systems Based on Renewable Resources

   Author : Natalia Kabalina; Mário Manuel Gonçalves Costa; Weihong Yang; Andrew Martin; Luis Barreiros Martins; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; district heating and cooling systems; polygeneration; refuse derived fuel; municipal solid waste; gasification.; Energy Technology; Energiteknik;

   Abstract : Traditional district heating (DH) and district heating and cooling (DHC) systems have to address two principal challenges: phase-out of fossil fuels in favor of renewables; and profit instability related to declines in heating and cooling demands along with electricity price fluctuations. These obstacles can be overcome at once through upgrading these systems to a polygeneration concept by means of a retrofitted air-steam gasifier and gas upgrading equipment, enabling the use of renewable feedstocks such as refuse derived fuel (RDF) and municipal solid waste (MSW).
