4. 2. Fluidized-Bed Reactor Systems for Chemical-Looping Combustion with Inherent Separation of CO2

   Author : Eva Johansson; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Chemical-Looping Combustion; Interconnected Fluidized Beds; Carbon Dioxide Capture;

   Abstract : In chemical-looping combustion (CLC) a gaseous fuel can be burnt with inherent separation of carbon dioxide. The system consists of two reactors, a fuel reactor and an air reactor and an oxygen-carrier in the form of metal oxide particles that transports oxygen from the air to the fuel. READ MORE

5. 3. Design and Operation of a 10 kWth Chemical-Looping Combustor for Solid Fuels

   Author : Nicolas Berguerand; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Interconnected Fluidized Beds; Oxygen Carrier; Chemical-Looping Combustion; Carbon Dioxide Capture; Solid Fuel Conversion;

   Abstract : The use of a 10 kWth chemical-looping combustor for solid fuels was investigated. The unit was designed, dimensioned and built and two types of fuel were tested: a South African coal and a petroleum coke from Mexico. Chemical-looping combustion is an alternative to normal combustion for CO2 capture. READ MORE

6. 4. 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.

7. 5. Hydrogen Production by Integration of Fluidized Bed Heat Exchangers in Steam Reforming

   Author : Viktor Stenberg; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; oxygen carrier aided combustion; chemical-looping combustion; bed-to-tube heat transfer.; steam reforming; fluidized bed heat exchanger;

   Abstract : The possibility to integrate fluidized beds as heat sources for steam reforming in industrial hydrogen production plants is examined in this work. The proposed processes include traditional catalytic steam reforming of natural gas (SMR), shift reactors and purification steps; the main difference is the reformer furnace. READ MORE
