“…This ferrite-based material is readily prepared via co-precipitation of all elements, unlike the additional modification of a Fe-based oxygen carrier by a catalyst component. Various Me-ferrites (Me = Ni, Co, Cu, Mn, Zn) have been investigated in chemical looping processes [112,150,151], among which the NiFe 2 O 4 and CoFe 2 O 4 show certain catalytic activity and redox stability during chemical looping dry reforming of CH 4 . Given the increase of alcohol feedstocks from chemical conversion of biomass, these ferrite-based bifunctional materials were further tested in chemical looping reforming of alcohol fuels, such as methanol and ethanol, for the production of value added fuels such as syngas.…”

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.

“…Similar results were observed in our previous work. 37 The peaks at about 630 C were similar for the NiO-iron ore, CuO-iron ore and iron ore, indicating that the additives had a small inuence on the reduction of Fe 3 O 4 . Similar to that of the CeO 2 -iron ore, the peaks at 743 C for the NiO-iron ore and at 745 C for the CuO-iron ore veried that the reduction temperature of the iron ore was decreased by introducing metallic oxides.…”

“…The fuel conversion efficiency was reached to a maximum of 92% while the heat demand is just 54% of heat utilized by the gasification of rice husk [26]. Wang, X., et al performed chemical looping combustion using thermo gravimetric analyzer and laboratory scale fluidized bed on pine saw dust with different metal ferrites synthesized by sol-gel method as an oxygen carrier and concluded that CuFe2O4 and CoFe2O4 are suitable oxygen carrier for biomass [23]. To test the effect of naturally available ores sintered manganese ore was used in biomass CLC process.…”

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.
