Summary: The study found that copper manganese spinel oxides are promising oxygen carriers for the CLOU and CLAS processes due to their high O-2 release capacity and fast release kinetics. Material properties of oxygen carriers can be improved by adjusting Cu:Mn ratios and synthesis conditions to optimize performance. After extended cycling tests, the oxygen carriers showed excellent stability and high resistance to attrition.

Summary: Biomass chemical looping gasification (BCLG) utilizes lattice oxygen from an oxygen carrier for high-quality syngas production without CO2 emissions. The main operating variables investigated in this study were the oxygen/biomass ratio (lambda), gasification temperature, and steam/biomass ratio (S/B). The results showed that the lambda significantly affected the process performance and syngas quality, while the temperature and S/B ratio had a minor impact.

Summary: Solid fuel chemical looping gasification technology requires the development of low-cost, easily available oxygen carrier particles, with Cu/Fe-based OCs from waste ore particles and bauxite residues showing promise for coal gasification. Among these OCs, red mud and Cu20Fe80@C exhibit better gasification performance and potential for Fischer-Tropsch synthesis and H-2-rich chemical synthesis. The study also reveals the importance of lattice oxygen donation capacity and alkali metal content in determining coal and char gasification rates.

Summary: Chemical looping combustion (CLC) is a technology that can generate heat and power while capturing CO2. Using biomass in CLC (bio-CLC) allows for negative CO2 emissions. This study investigates the interaction between alkalis in biomass and the process, focusing on charcoal impregnated with alkali chlorides. The results show that impregnation with alkalis improves the gasification rate, with carbonates resulting in earlier and more permanent defluidization compared to chlorides. Partial agglomeration and retention of alkalis in the oxygen carrier are observed, with similar reactivity noticed with CH4 and H2.

Summary: Electronic waste is a major pollutant due to high demand and short lifespan, so recycling and extracting valuable components is essential. In this study, a printed circuit board is used to produce valuable gases and extract metals through pyrolysis and combustion processes. The co-combustion process using coal and rice straw blends in the chemical looping combustion (CLC) shows promising results with reduced activation energy.

Summary: This study evaluated the stability of a CuO/Al2O3 impregnated oxygen carrier during methane chemical looping combustion at high oxygen carrier to fuel ratios. The research found that low oxygen carrier conversion variation reduced copper loss from particles, but reoxidizing the oxygen carrier at high temperatures was difficult due to the formation of CuAlO2. Operating at temperatures around 800 degrees C with low solid conversion variation is recommended to limit copper loss while maintaining physical stability.

Summary: Perovskite oxides LaNi1-xCoxO3 (x = 0.0; 0.2; 0.5; 1.0) were studied in chemical looping combustion of methane. Nickel substitution for cobalt decreased active oxygen, while cobalt insertion improved re-oxidation rates and reduced coke deposits. The best CLC sample in the series was found to be LaNi0.5Co0.5O3 due to its faster complete reduction and resistance to coke formation.

Summary: This study investigated the use of a low-cost Fe-based residue as an oxygen carrier in the Chemical Looping Combustion (CLC) and Chemical Looping Reforming (CLR) processes with biogas. The results showed that the methane combustion efficiency in the CLC process was higher (around 86%) compared to other low-cost Fe-based materials. The dry reforming of biogas in the CLR process achieved about 55% methane conversion and a yield of 1.3 mol (CO + H2)/mol CH4 for syngas production.

Summary: Chemical looping (CL) is a promising technology with CO2 capture capabilities in industrial applications. Iron based (Fe-based) materials are the most likely candidates for oxygen carriers due to their economic and eco-friendly characteristics. This review provides a comprehensive overview of Fe-based oxygen carriers, including their preparation methods, characteristics, and reaction mechanisms. The application of Fe-based oxygen carriers in chemical looping processes and the recent progress in reaction mechanism studies are also discussed. The challenges and prospects of Fe-based oxygen carriers are presented along with effective strategies. This review aims to provide insights into the practical application of Fe-based oxygen carriers in chemical looping.

Summary: The aim of this study was to investigate the effect of increased operating pressure on the fuel conversion in chemical looping combustion systems using ilmenite as the oxygen carrier. Fluid dynamics and reaction kinetics were considered to determine suitable design parameters. The results showed that incomplete combustion occurred at atmospheric conditions, while some improvement was achieved at pressurized conditions, leading to higher energy efficiency.

Summary: The study investigated the redox kinetics of a new perovskite oxygen carrier and found that its oxidation rate is much faster than that of natural manganese ore and ilmenite, with only a fast initial stage observed. The effects of temperature, O2 concentrations, and reducing gas type were explored using MFB-TGA method, providing important insights for reactor design in CLC applications.
