Iron-based oxygen carriers in chemical looping conversions: A review

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 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

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

Optimization of Hydrogen Production by Chemical-Looping Auto- Thermal Reforming Working with Ni-based Oxygen-Carriers

Chemical-Looping auto-thermal Reforming (CLRa) is a new process for hydrogen production from natural gas that uses the same principles as Chemical-Looping Combustion (CLC). The main difference with CLC is that the desired product is syngas (H2 + CO) instead of CO2 + H2O. For that, in the CLRa process the air to fuel ratio is kept low to prevent the complete oxidation of the fuel. The major adva...
