Effect of H2S on Reactivity of Oxygen Carrier Particle for Chemical Looping Combustion

Effect of support on reactivity and selectivity of Ni- based oxygen carriers for Chemical-Looping Combustion

Different Ni-based oxygen carriers were prepared by dry impregnation using -Al2O3 as support. The reactivity, selectivity during methane combustion, attrition rate and agglomeration behaviour of the oxygen carriers were measured and analyzed in a termogravimetric analyzer and in a batch fluidized bed during multicycle reductionoxidation tests. * Manuscript

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...

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

Chemical-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...
