“…For example, CaSO 4 from natural anhydrite is a low cost material and has much higher oxygen transport capacity than other proposed materials These reactions have exhibited low reaction rates [274][275][276][277][278]. In addition, simulation results based on chemical equilibrium show that small fractions of CO and H 2 can not be converted [278,279].…”

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.

“…Fe based oxygen carries are relatively inexpensive and environmentally safe, but their reactivity is worse than the Ni based ones, their reduction and oxidation rates are much lower [21,22] . Oxygen carriers of metal oxides like Ni based, Cu based, Co based and Mn based carriers will inevitably have some leakage to environment and become second pollution sources, so CaSO 4 has been considered to be a new type of oxygen carries by some researchers, which is much more cheaper and environmentally friendly, and Huazhong University of Science and Technology, Southeast University and CANMET Energy Technology Centre in Canada have done researches in this field [11,23,24] .…”

Multicycle investigation of a sol‐gel‐derived Fe₂O₃/ATP oxygen carrier for coal chemical looping combustion

Fe-based oxygen-carrier particles with attapulgite (ATP) as a support material for coal chemical looping combustion (CLC) have been prepared using a sol-gel approach. The multiredox characteristics of the prepared Fe4ATP6 (Fe 2 O 3 to ATP mass ratio of 40:60) were experimentally examined in a batch fluidized bed reactor at 9008C. The experimental results indicated that the synergistic reactions between ATP and Fe 2 O 3 increased the coal conversion. Fe4ATP6 exhibited high reactivity, particularly for low-rank coals, in the CLC process. The improved pore structure and surface area were responsible for the high reactivity of Fe4ATP6. In 60 redox cycles, H 2 was mainly generated in the outlet gas as the carbon conversion efficiency had reached 95%, and both the coal combustion efficiency and CO 2 capture efficiency were greater than 95%.
