Research Progress and Perspectives of Solid Fuels Chemical Looping Reaction with Fe-Based Oxygen Carriers


Chemical looping (CL) is regarded as a promising technology in industrial applications, because of its inherent characteristic of CO2 capture.




The technique of CL is applied in solid fuels fields, including chemical looping combustion (CLC), chemical looping gasification (CLG), chemical looping reforming (CLR), chemical looping water splitting (CLWS), and oxygen carrier aided combustion (OCAC).


Oxygen carrier is a core media in chemical looping reaction, which plays the role of transporting oxygen and has the function of decreasing the energy penalty of air separation. Among all oxygen carriers, iron-based (Fe-based) materials are of most possibilities to be applied in industrial field, because of its economical and eco-friendly characteristics. Some reviews have reported the Fe-based oxygen carrier in CL application.



However, the related preparation methods, overall application of CL and theoretical reaction calculation of Fe-based oxygen carriers have not been covered comprehensively. In this Review, the general view of Fe-based oxygen carrier including iron ores and artificial synthesis are reviewed.



In addition, the different synthesis methods of Fe-based oxygen carrier are meticulously and profoundly summarized, involving mechanical mixing, impregnation, spraying drying, freeze granulation, sol–gel, solution combustion, and coprecipitation method. Then, the characteristics of Fe-based oxygen carrier from the perspectives of thermodynamics, redox kinetics analysis, antisintering and wear property of iron oxides are discussed in detail.


Furthermore, the chemical looping reaction mechanism of Fe-based oxygen carriers is reviewed from the perspectives of reaction and oxygen carrier migration mechanism. Moreover, this review summarizes the application of Fe-based oxygen carrier in CLC, CLG, CLR, CLWS, and OCAC. And the recent progress of reaction mechanism of oxygen carrier by density functional theory (DFT) calculations and machine learning are further presented.


Finally, the challenges and prospects for Fe-based oxygen carrier with the corresponding effective strategies are proposed. It is expected that this Review may provide insights into the Fe-based oxygen carrier and the practical application of chemical looping.

Does AI pose a threat to sustainable development?

Image
  The 2025 World Economic Forum, being held in Davos from Monday to Friday under the theme " Collaboration for the Intelligent Age ", is expected to foster a spirit of cooperation and optimism in the digital age in a more sustainable way, despite the different positions of the participants and global uncertainties. Three experts share their views on the issue with China Daily. Projected estimates indicate that advanced artificial intelligence (AI) systems will necessitate over $1 trillion in investments for cloud and enterprise data center infrastructure within the next five years. The AI infrastructure includes servers equipped with graphics processing units (GPUs) or custom accelerators, dedicated networks, storage solutions and specialized facilities, which are all factors that demand significant capital investment. Therefore, evaluating the scale, potential returns and environmental impact of AI's rapid development and application is essential. The rise of AI will si...

'Our model of cosmology might be broken': New study reveals the universe is expanding too fast for physics to explain

Image
 A recent study has revealed a puzzling discrepancy in our understanding of the universe’s expansion rate, suggesting that our current cosmological models may need a significant overhaul. The crux of the issue lies in the Hubble constant (H₀), a measure of the universe's expansion rate, which appears to differ depending on how it is calculated. For decades, scientists have relied on two primary methods to determine H₀. The first involves observing the cosmic microwave background (CMB), the faint afterglow of the Big Bang, and extrapolating the universe's expansion rate using early-universe physics. The second method uses the local universe, measuring distances to nearby galaxies via "standard candles" like Cepheid variables and Type Ia supernovae. However, these two methods yield conflicting results. The CMB method, based on data from missions like Planck, estimates H₀ to be around 67.4 kilometers per second per megaparsec (km/s/Mpc) . In contrast, local measurements...

Newly discovered asteroid with 100x Hiroshima bomb power may hit Earth in 2032—what are the odds of its impact?

Image
  In December 2024 , astronomers discovered an asteroid named 2024 YR4, estimated to be approximately 60 meters (196 feet) in diameter. Current assessments indicate that this asteroid has a 1 in 43 chance (approximately 2.3%) of impacting Earth on December 22, 2032. If 2024 YR4 were to collide with Earth, the energy released would be substantial, potentially equivalent to 100 times the energy of the Hiroshima atomic bomb . Such an impact could devastate a metropolitan area, causing significant destruction and loss of life.
