“…The type A-1 process, also known as chemical looping combustion (CLC) [26], can be divided into two separate half-cycles: In the reduction half-cycle, the metal oxide is reduced, whilst the carbonaceous fuel is fully oxidized to CO 2 and H 2 O; the reduced metal oxide is regenerated in the re-oxidation half-cycle by different re-oxidizing agents, such as air, steam or CO 2 , simultaneously producing power, H 2 and CO, respectively. In addition, the gaseous O 2 released from some metal oxides upon heating in the reduction half-cycle (i.e., oxygen uncoupling) can directly react with the fuel, which avoids the gas-solid reactions between the fuel and oxygen carrier.…”

“…During the early stages of development, research focused on the metal oxide materials with a single function as CO 2 accepter or oxygen storage, which are mainly used for conventional chemical looping combustion and reforming processes. The advances were reported in a few review papers [1,2,14,21,26,38,39]. More recently, a novel process, so-called catalyst-assisted chemical looping, was proposed with the aim of maximal CO 2 utilization.…”

Combining chemical looping with a traditional fuel conversion process yields a promising technology for low-CO2-emission energy production. Bridged by the cyclic transformation of a looping material (CO2 carrier or oxygen carrier), a chemical looping process is divided into two spatially or temporally separated half-cycles. Firstly, the oxygen carrier material is reduced by fuel, producing power or chemicals. Then, the material is regenerated by an oxidizer. In chemical looping combustion, a separation-ready CO2 stream is produced, which significantly improves the CO2 capture efficiency. In chemical looping reforming, CO2 can be used as an oxidizer, resulting in a novel approach for efficient CO2 utilization through reduction to CO. Recently, the novel process of catalyst-assisted chemical looping was proposed, aiming at maximized CO2 utilization via the achievement of deep reduction of the oxygen carrier in the first half-cycle. It makes use of a bifunctional looping material that combines both catalytic function for efficient fuel conversion and oxygen storage function for redox cycling. For all of these chemical looping technologies, the choice of looping materials is crucial for their industrial application. Therefore, current research is focused on the development of a suitable looping material, which is required to have high redox activity and stability, and good economic and environmental performance. In this review, a series of commonly used metal oxide-based materials are firstly compared as looping material from an industrial-application perspective. The recent advances in the enhancement of the activity and stability of looping materials are discussed. The focus then proceeds to new findings in the development of the bifunctional looping materials employed in the emerging catalyst-assisted chemical looping technology. Among these, the design of core-shell structured Ni-Fe bifunctional nanomaterials shows great potential for catalyst-assisted chemical looping.

“…Byrne et al have studied the synthesis of CuAlO 2 powder by solid‐state reaction between CuO and boehmite, and the subsequent reduction of delafossite thin films to copper and alumina. Another technological area in which Cu‐Al‐O materials have received increased attention is that of chemical looping combustion (CLC) reactions …”

Partial reduction of bulk CuAlO2 results in hierarchical structures wherein there are copper‐alumina regions with widely differing morphologies and scale. At the finest level, the distribution of the 2 phases is at the nanoscale. By means of atomic resolution STEM and electron diffraction, the nanocomposite regions were shown to consist of a dense array of metallic copper platelets dispersed in a matrix of θ‐Al2O3. The copper nanoplatelets were single crystal, and they all exhibited the same orientation relationship with the matrix, namely [110]Cu//[010]θ‐Al2O3, (111)Cu//(402¯)θ‐Al2O3. It was shown that the 2‐phase regions where the copper exhibited a significantly coarser, globular morphology, resulted from discontinuous coarsening. Interestingly, a change in the matrix phase from θ‐ to δ‐alumina was also observed as a result of the coarsening reaction. It is believed that in the nanocomposite regions, the θ‐alumina phase was stabilized by the lower interfacial energy between the copper (110) platelets and the matrix.

“…Later, it was also recognized as a potential technique to control CO2 emission from thermal power plants. The research works on chemical looping combustion has been summarized in different review articles based on process [13], [14], [15] , Solid fuels [16], [17], use of natural ores as oxygen carriers [18] etc. Adanez, J., et al published a broad review over utilization of 700 oxygen carriers in CLC process [19] .…”

World depends on fossil fuel combustion for thermal energy generation. Fossil fuel combustion leads to the generation of CO2 and extinction of non-renewable resources. To meet the future energy demands replacement of existing technologies should take place in the view of large quantities of GHG's emissions from fossil fuels and their extinction. Chemical looping combustion (CLC) is primarily a combustion technique with an inherent separation of CO2 from the flue gases. Due to its advantage of negative CO2 emissions, chemical looping combustion got attention of many researchers since last one and half decade. Recent research advancements in the CLC provided a platform for further research and developments in chemical looping combustion of biomass. This paper reviews the CLC of biomass to present the overview of chemical looping combustion technology and its status of biomass utilization as a fuel in CLC reactors.
