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...
متن کاملComputational Fluid Dynamics Study of a Complete Coal Direct Chemical Looping Sub-Pilot Unit
The present Computational Fluid Dynamics (CFD) work deals with the modeling of complete coal direct chemical looping sub-pilot unit which use coal as fuel and ferric oxide supported on alumina as an oxygen carrier. The 2D CFD model of the complete arrangement incorporating both fuel and air reactors and their inter-connecting parts was solved using FLUENT. The CFD model wa...
متن کاملHydrogen production with CO2 capture by coupling steam reforming of methane and chemical–looping combustion (SR-CLC) — Use of an iron-based waste product as oxygen carrier burning a PSA tail gas
In this work it is analyzed the performance of an iron waste material as oxygen carrier for a chemical-looping combustion (CLC) system. CLC is a novel combustion technology with the benefit of inherent CO2 separation that can be used as a source of energy for the methane steam reforming process (SR). The tail gas from the PSA unit is used as fuel in the CLC system. The oxygen carrier behaviour ...
متن کاملSolid 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...
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...
