Using Low-Cost Iron-Based Materials as Oxygen Carriers for Chemical Looping Combustion

Solid waste management of a chemical-looping combustion plant using Cu-based oxygen carriers.

Waste management generated from a Chemical-Looping Combustion (CLC) plant using copper-based materials is analyzed by two ways: the recovery and recycling of the used material and the disposal of the waste. A copper recovery process coupled to the CLC plant is proposed to avoid the loss of active material generated by elutriation from the system. Solid residues obtained from a 10 kWth CLC proto...

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

Effect of pressure on the behavior of Copper-, Iron-and Nickel-based Oxygen Carriers for Chemical-Looping Combustion

Effect of gas composition in Chemical-Looping Combustion with copper based oxygen carriers: Fate of sulphur

Chemical-Looping Combustion (CLC) is an emerging technology for CO2 capture because separation of this gas from the other flue gas components is inherent to the process and thus no energy is expended for the separation. Natural or refinery gas can

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...
