1. 26. Pressurized entrained flow gasification of pulverized biomass : Experimental characterization of process performance

   Författare :Fredrik Weiland; Thomas Kolb; Luleå tekniska universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energy Engineering; Energiteknik;

   Sammanfattning : The anthropogenic emissions of greenhouse gases (e.g. CO2), mostly connected to the use of fossil fuels, to the atmosphere have increased during the last century and there is significant evidence that this is the main reason for the recent global temperature rise. LÄS MER

3. 27. Polygeneration District Heating and Cooling Systems Based on Renewable Resources

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

   Sammanfattning : 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).

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

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

   Sammanfattning : 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.

5. 29. Entrained flow gasification of biomass : On atomisation, transport processes and gasification reactions

   Författare :Mikael Risberg; Kevin Whitty; Luleå tekniska universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energy Engineering; Energiteknik;

   Sammanfattning : Since the energy consumption in the world is increasing together with an increase of greenhouse gas emission it is of importance to find alternatives to fossil fuels. Biomass is one of the alternative energy sources which is both renewable and CO2 neutral. LÄS MER

7. 30. Strategies for controlling solid biomass conversion in dual fluidized bed gasifiers

   Författare :Teresa Berdugo Vilches; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; char gasification; operating conditions; steam reforming; feldspar.; bauxite; segregation; olivine; in situ gas upgrading; ilmenite; dual fluidized bed; tar removal;

   Sammanfattning : In the chemical industry, Synthesis Gas (syngas) has been traditionally produced by steam reforming of natural gas and naphtha. Steam gasification of biomass offers an alternative route for the production of syngas from renewable sources. LÄS MER
