2. 1. Innovative Oxygen Carriers for Chemical-looping Combustion

   Author : Dazheng Jing; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Chemical-looping with oxygen uncoupling; Combined manganese oxides; Chemical-looping combustion; CuO-based oxygen carrier; Oxygen carrier;

   Abstract : Chemical-looping combustion (CLC) and chemical-looping with oxygen uncoupling (CLOU) are combustion technologies where carbon dioxide is inherently obtained in pure form without any gas separation step. In the processes, fuel is introduced to the fuel reactor and combustion air is introduced to the air reactor. READ MORE

4. 2. Copper in Chemical-Looping Combustion (CLC) and Chemical-Looping with Oxygen Uncoupling (CLOU)

   Author : Mehdi Arjmand; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; chemical-looping combustion CLC ; chemical-looping with oxygen uncoupling CLOU ; copper; CO2-capture; kinetic; oxygen carrier;

   Abstract : The chemical-looping combustion (CLC) and chemical-looping with oxygen uncoupling (CLOU) processes are attractive solutions for efficient combustion with inherent separation of carbon dioxide. These processes use a metal oxide as an oxygen carrier to transfer oxygen from an air to a fuel reactor where the fuel, or gasification products of the fuel, reacts with the oxygen carrier.

5. 3. 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

6. 4. Combined Iron-Manganese Oxides for Chemical-Looping with Oxygen Uncoupling

   Author : Golnar Azimi; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Iron-manganese oxide.; Keywords: CO2 capture; Chemical-looping with oxygen uncoupling; Chemical-looping combustion;

   Abstract : AbstractThe most important factor affecting global warming is the increased concentrations of greenhouse gases in the atmosphere. Carbon dioxide is considered as the most important anthropogenic greenhouse gas. READ MORE

7. 5. Mixed Oxide Oxygen Carriers for Chemical-Looping Combustion

   Author : Peter Hallberg; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Chemical-Looping Combustion CLC ; ilmenite; calcium manganite; oxygen carrier; CO2 capture; Chemical-Looping with oxygen uncoupling;

   Abstract : Chemical-Looping Combustion is a promising method for combustion with inherent carbon dioxide capture. Oxygen is provided to the fuel with a solid oxygen carrier. The oxygen carrier is circulated between the reactor for fuel oxidation and another reactor where it is reoxidized with air. A good performing oxygen carrier is vital for this process. READ MORE
