2. 1. Capture of CO2 from solid fuels using Chemical-Looping Combustion and Chemical-Looping Oxygen Uncoupling

   Author : Henrik Leion; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; chemical-looping with oxygen uncoupling; fluidized bed; gasification; CO2-capture; biofuels; oxygen carrier; chemical looping combustion; CLOU; petroleum coke; coal; CLC;

   Abstract : In order to meet the global demand of CO2 neutral energy, chemical-looping combustion could play an important role. Oxygen can be transferred from the combustion air to the fuel by means of oxygen carrying metal oxide particles circulating between two reactors, an air- and a fuel reactor. READ MORE

4. 2. Chemical-Looping Combustion with Solid Fuels

   Author : Henrik Leion; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; petroleum coke; fluidized bed; oxygen carrier; ilmenite; volatiles; gasification; sulphur dioxide; coal; iron oxide; chemical looping combustion; CLC;

   Abstract : In order to meet the global demand of CO2 neutral energy production, chemical-looping combustion could play an important role. With this technique it is possible to capture CO2 without an excessive energy penalty. READ MORE

5. 3. CO2 Capture using Chemical-Looping Combustion – Operational Experience with Gaseous and Solid Fuels

   Author : Carl Johan Linderholm; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; nickel oxide; coal; natural gas; chemical-looping combustion CLC ; oxygen carrier; CO2 capture; manganese ore; interconnected fluidized beds; ilmenite;

   Abstract : CO2 capture and storage has been proposed as an alternative to mitigate global warming. Chemical-looping combustion (CLC) is an unmixed combustion concept where fuel and combustion air are kept separate by means of an oxygen carrier, and the CO2 capture is inherently achieved.

6. 4. Experimental study of a Volatiles Distributor for Improving the Cross-sectional Gas Distribution in Fluidized Beds

   Author : Xiaoyun Li; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Fuel reactor; Fluidization regimes; Gas-solid contacting; Biomass; Chemical looping combustion; Volatiles distributor; Internal baffles; CO2 removal;

   Abstract : Chemical looping combustion (CLC) is a promising carbon capture technology due to its inherent CO2 separation. Significant progress has been made in CLC of solid fuels in recent years. READ MORE

7. 5. Analysis of gas turbine systems for sustainable energy conversion

   Author : Marie Anheden; KTH; []
   Keywords : ;

   Abstract : Increased energy demands and fear of global warming due tothe emission of greenhouse gases call for development of newefficient power generation systems with low or no carbondioxide(CO2) emissions. In this thesis, two different gasturbine power generation systems, which are designed with theseissues in mind, are theoretically investigated and analyzed. READ MORE
