What is Chemical-Looping-Combustion (CLC)?
Two interconnected reactors, (air reactor and a fuel reactor) are used as shown in the figure.
A metal oxide is used as an oxygen carrier for the fuel.
Reduced metal is then returned to the air reactor for reoxidation.
This avoids mixing or dilution of combustion products with nitrogen, thereby providing directly concentrated sequestration ready stream of with a high CO2 content
Process appears to be cost effective since separation costs are reduced but need detailed engineering models to assess the potential of this technology and optimum process conditions.
Study the role of the particle residence time on the chemical looping combustion reactor performance.
Examine the role of intraparticle diffusion on the operating character of the recirculating system.
Develop a phenomenological model for two inter-connected reactors as shown in the diagram.
