Identification of operational regions in the Chemical-Looping with Oxygen Uncoupling (CLOU) process with a Cu-based oxygen carrier

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

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...

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...

Evaluation of CuO/MgAl2O4 in Biomass Chemical Looping Gasification with Oxygen Uncoupling

Chemical looping gasification (CLG) is a promising method for the utilization of biomass to produce syngas. However, its realization is largely dependent on the use of an oxygen carrier with a high and stable reactivity in cyclic reduction and oxidation. This work focused on the improvement of reactivity and stability of CuO in chemical looping gasification via the addition of MgAl2O4 as an ine...
