Summary: One of the most significant topics in chemical looping reforming technology is the design and preparation of appropriate oxygen carriers with high reactivity and excellent stability. This study focuses on the chemical looping reforming of methane using cobalt-doped Ce-based oxygen carriers synthesized via the solution combustion method with the assistance of coconut shell. The introduction of cobalt decreases the crystallite size, increases oxygen vacancy concentration and lattice oxygen mobility, and the addition of coconut shell further enhances these positive changes and the interaction between Ce and Co.

Summary: The redox kinetics of oxygen carrier in chemical looping plays a crucial role in material preparation, reactor design, and process demonstration. This study presents a DFT-based microkinetic rate equation theory to predict the heterogeneous kinetics of Fe2O3 reduction by CO in chemical looping. By combining density functional theory (DFT) calculations with transition state theory (TST) and bulk diffusion consideration, a rate equation is developed to bridge the gap between elementary surface reactions and grain conversion. Experimental data validation shows the accuracy and effectiveness of the developed theory in predicting the redox kinetics of oxygen carriers.

Summary: To address the scale-up challenges of Chemical Looping Processes, the development of efficient and affordable oxygen carriers is crucial. Ilmenite, an ore-derived oxygen carrier, has been identified as an abundant and low-cost option. This paper provides insights into its preparation, reactivity, and performance compared to other carriers, along with its thermodynamic properties and kinetics. The paper also explores its compatibility with various fuels (solid, liquid, gaseous, including biofuels) and discusses important considerations such as cost, environmental sustainability, oxygen transport capacity, as well as issues related to fluidized bed reactors, such as agglomeration and attrition behavior. Furthermore, the paper investigates the interaction between ilmenite and fuels, including the impact of impurities and coke deposition on the gasification rate of solid fuels.

Summary: (La1-xSrx)MnO3 +/-delta perovskites prepared by co-precipitation have been evaluated for a chemical looping process with fuel CH4 and oxidants CO2 or O2. The higher the Sr content, the higher the CH4 conversion and oxygen transport capacity with CO2, but the reaction with CO2 decreases. However, the oxygen transport capacity with O2 increases as Sr content increases.

Summary: This work investigates the behavior of coal-derived chlorine in chemical looping combustion (CLC) and the potential adverse impacts of primary gaseous chlorine (HCl) on a Cu-based oxygen carrier (OC). The inactivation mechanism of the sol-gel-derived CuO/Al2O3 OC is studied. It is found that HCl is the main gaseous chlorine in coal CLC and shows high reactivity towards CuO. The presence of HCl can result in corrosion and degradation of the OC.

Summary: The combination of methane dehydroaromatization (MDA) and chemical looping (CL) combustion of hydrogen can overcome the thermodynamic constraints limiting conversion. The development of selective hydrogen-oxidation oxygen carriers in the CL is crucial for improving MDA performance. A novel oxygen carrier, silica-encapsulated Fe2O3, demonstrated high overall methane conversion and aromatics yield in a recirculating system. The silica layer prevented aromatics diffusion and promoted hydrogen transport and oxidation, while close physical contact between iron oxide particles and silica facilitated hydrogen conversion without full depletion of iron oxides.

Summary: The study investigated the effects of MPS, PEG, TU and ETU on copper electrodeposition and found that the additives have inhibitory effects on the process. MPS and PEG inhibit copper deposition through direct adsorption on the cathode surface, while TU and ETU inhibit it through complex intermediate reactions, resulting in flatter and finer-grained deposits. These findings suggest that TU and its derivatives are suitable additives for direct copper electrodeposition at low copper ion concentration.

Summary: Chemical-looping combustion (CLC) is a promising technology for CO2 capture with low energy consumption, but carbon deposition from methane poses a challenge. This study investigated carbon formation behaviors of four typical oxygen carriers (OCs) and proposed a strategy to eliminate carbon by arranging them in a fixed-bed reactor. The findings show that NiO/ZrO2 OC is prone to carbon formation, while CuO/SiO2 OC has high CH4 conversion and minimal carbon formation. Mixing these OCs in a suitable sequence can significantly enhance CLC efficiency and resistance to carbon deposition.

Summary: Carbon dioxide and methane are major greenhouse gases contributing to global warming, but dry reforming of methane (DRM) can convert them into useful products. However, the coking formation on nickel-based catalysts is a challenge for industrialization. Confined indium-nickel intermetallic alloy nanocatalysts show superior resistance to coking in DRM, with the In0.5Ni@SiO2 catalyst demonstrating the best balance of carbon deposition resistance and reactivity. This study provides guidance on designing high-performance catalysts for methane dry reforming to utilize greenhouse gases efficiently.

Summary: The use of machine learning to predict the performance of specific adsorbents in phosphate adsorption shows great promise in saving time and revealing underlying mechanisms. However, the small size of the dataset and insufficient detailed information limits the model training process and the accuracy of results. To address this, the study employs a fuzzing strategy that replaces detailed numeric information with descriptive text messages on the physiochemical properties of adsorbents. This strategy allows the recovery of discarded samples with limited information, leading to accurate prediction of adsorption amount, capacity, and kinetics. The study also finds that phosphate uptake by adsorbents is generally through physisorption, with some involvement of chemisorption. The framework established in this study provides a practical approach for quickly predicting phosphate adsorption performance in urgent scenarios, using easily accessible information.
