“…It was speculated that the active phase was a combined metal oxide of the form Fe Mn 1− O 3 . Oxygen carriers composed of Mn-Fe had earlier been tested by Lambert et al [110], but the CLOU effect was not observed in this investigation. Azimi et al [74,[111][112][113] has conducted extensive investigations of this system using spray-dried oxygen carriers and using both solid and gaseous fuels.…”

Chemical-looping with oxygen uncoupling (CLOU) is a novel combustion technology with inherent separation of carbon dioxide. The process is a three-step process which utilizes a circulating oxygen carrier to transfer oxygen from the combustion air to the fuel. The process utilizes two interconnected fluidized bed reactors, an air reactor and a fuel reactor. In the fuel reactor, the metal oxide decomposes with the release of gas phase oxygen (step 1), which reacts directly with the fuel through normal combustion (step 2). The reduced oxygen carrier is then transported to the air reactor where it reacts with the oxygen in the air (step 3). The outlet from the fuel reactor consists of only CO 2 and H 2 O, and pure carbon dioxide can be obtained by simple condensation of the steam. This paper gives an overview of the research conducted around the CLOU process, including (i) a thermodynamic evaluation, (ii) a complete review of tested oxygen carriers, (iii) review of kinetic data of reduction and oxidation, and (iv) evaluation of design criteria. From the tests of various fuels in continuous chemical-looping units utilizing CLOU materials, it can be established that almost full conversion of the fuel can be obtained for gaseous, liquid, and solid fuels.

“…The combined oxide system Fe-Mn appears to be especially promising due to its favourable thermodynamics (Crum et al, 2009;Wickham, 1969), which also has been confirmed by experimental work (Azimi et al, 2013a). Work focused on the Fe/Mn system has been done both in laboratory scale (Azimi et al, 2011(Azimi et al, , 2013aKsepko et al, 2010;Lambert et al, 2009) and operation in 300 W Chemical looping combustor (Rydén et al, 2011b).…”

“…Lambert et al [251] studied Fe-Mn mixed oxides to check for eventual cooperative effects between both metals. Ksepko et al [252] also prepared oxygen-carriers consisting of Fe 2 O 3 -MnO 2 supported on ZrO 2 and sepiolite and observed that both carriers exhibited excellent reaction performance and thermal stability for CLC process at 800 ºC.…”

This work is a comprehensive review of the Chemical-Looping Combustion (CLC) and Chemical-Looping Reforming (CLR) processes reporting the main advances in these technologies up to 2010. These processes are based on the transfer of the oxygen from air to the fuel by means of a solid oxygen-carrier avoiding direct contact between fuel and air for different final purposes. CLC has arisen during last years as a very promising combustion technology for power plants and industrial applications with inherent CO 2 capture which avoids the energetic penalty present in other competing technologies.CLR uses the chemical looping cycles for H 2 production with additional advantages if CO 2 capture is also considered.The review compiles the main milestones reached during last years in the development of these technologies regarding the use of gaseous or solid fuels, the oxygen-carrier development, the continuous operation experience, and modelling at several scales. Up to 2010, more than 700 different materials based on Ni, Cu, Fe, Mn, Co, as well as other mixed oxides and low cost materials, have been compiled. Especial emphasis has been done in those oxygen-carriers tested under continuous operation in Chemical-Looping 2 prototypes. The total time of operational experience (≈ 3500 h) in different CLC units in the size range 0.3-120 kW th , has allowed to demonstrate the technology and to gain in maturity. To help in the design, optimization, and scale-up of the CLC process, modelling work is also reviewed. Different levels of modelling have been accomplished, including fundamentals of the gas-solid reactions in the oxygen-carriers, modelling of the air-and fuel-reactors, and integration of the CLC systems in the power plant. Considering the great advances reached up to date in a very short period of time, it can be said that CLC and CLR are very promising technologies within the framework of the CO 2 capture options.
