CaxLa1–xMn1–yMyO3−δ(M = Mg, Ti, Fe, or Cu) as Oxygen Carriers for Chemical-Looping with Oxygen Uncoupling (CLOU)

Characterization of natural copper ore in anthracite fueled Chemical-Looping with Oxygen Uncoupling (CLOU)

Chemical Looping with Oxygen Uncoupling (CLOU) is an advanced approach proposed for improving the utilization degree of solid fuels and speeding up the reaction rate in Chemical-Looping Combustion technology (CLC). In CLOU system, OC circulates between fuel reactor (FR) and air reactor (AR), providing gaseous oxygen for the combustion of fuels (in FR) and then being regenerated by absorbing gas...

Characterization of a Sol-gel Derived CuO/CuAl2O4 Oxygen Carrier for Chemical Looping Combustion (CLC) and Chemical Looping with Oxygen Uncoupling (CLOU) of Gaseous Fuels

Reduction Kinetics of Cu-, Ni-, and Fe-based Oxygen Carriers Using Syngas (CO+H2) for Chemical-Looping Combustion

The reactivity of three Cu-, Fe-, and Ni-based oxygen carriers to be used in a chemical-looping combustion (CLC) system using syngas as fuel has been analyzed. The oxygen carriers exhibited high reactivity during reduction with fuel gases present in syngas (H2 and CO), with average values in the range 8-30 % min. No effect of the gas products (H2O, CO2) on the reduction reaction rate was detect...

Mapping of the Range of Operational Conditions for Cu-, Fe-, and Ni- based Oxygen Carriers in Chemical-Looping Combustion

Chemical-Looping Combustion (CLC) is a two-step combustion process that produces a pure CO2 stream, ready for compression and sequestration. A CLC system is composed by two reactors, an air and a fuel reactor, and an oxygen carrier circulating between the reactors, which transfers the oxygen necessary for the fuel combustion from the air to the fuel. This system can be designed similar to a cir...
