Reduction kinetics of CoO-NiO/Al2O3 oxygen carrier for chemical-looping combustion
This communication reports the reduction mechanism and kinetics of CoO-NiO/Al2O3 oxygen carrier using methane as the reduction gas. Kinetics experiments are performed in a novel fluidized bed CREC riser simulator under turbulent fluidized bed reaction conditions. A shrinking-core model is used for the kinetic modeling assuming spherical grains of the oxygen carrier particles. The XRD analysis s...
متن کاملSyngas combustion in a 500 Wth Chemical-Looping Combustion system using an impregnated Cu-based oxygen carrier
Chemical-Looping Combustion (CLC) is an emerging technology for CO2 capture because separation of this gas from the other flue gas components is inherently to the process and thus no energy is expended for the separation. For its use with coal as fuel in power plants, a process integrated by coal gasification and CLC would have important advantages for CO2 capture. This paper presents the combu...
متن کاملChemical-Looping Combustion and Gasification of Coals and Oxygen Carrier Development: A Brief Review
Chemical-looping technology is one of the promising CO2 capture technologies. It generates a CO2 enriched flue gas, which will greatly benefit CO2 capture, utilization or sequestration. Both chemical-looping combustion (CLC) and chemical-looping gasification (CLG) have the potential to be used to generate power, chemicals, and liquid fuels. Chemical-looping is an oxygen transporting process usi...

متن کاملTemperature variations in the oxygen carrier particles during their reduction and oxidation in a chemical-looping combustion system
A particle reaction model including mass and heat transfer has been developed to know the temperature variations produced inside the oxygen carrier particles during the cyclic reduction and oxidation reactions taking place in a Chemical-Looping Combustion (CLC) system. The reactions of the different oxygen carriers based on Cu, Co, Fe, Mn, and Ni during the reduction with fuel gas (CH4, CO, and...
