Summary: The results of the n-hexane oxidation process in a fluidized bed reactor with a catalytic bed are presented. Baffles were used to modify the flow in the reactor and improve the process efficiency. The best results were achieved with the use of horizontal elements in the form of grids, which significantly improved the conversion of n-hexane to carbon dioxide.

Summary: In this study, the effects of concentration models on the electrical capacitance tomography (ECT) measurements of gas-fluidized beds were experimentally investigated. The results showed that the concentration models can significantly influence the measured solid concentrations and the threshold selection for identifying bubbles and emulsion phase in gas-fluidized beds. A new concentration model based on a power function was proposed, and the optimal exponent alpha was determined through experimental fitting.

Summary: X-ray micro-computed tomography was used to study the effect of stabilizers on the microstructure of fresh sorbets. It was found that adding hydroxypropylmethylcellulose (HPMC) as a stabilizer led to an increase in air bubble quantity and a decrease in size, as well as a reduction in ice crystal size. The surfactant properties of HPMC may be related to its impact on the ice phase, potentially preventing crystal growth during freezing.

Summary: Swarm effects in bubble columns are caused by the interaction between bubbles at higher gas holdup, where the flow around individual bubbles affects the movement of subsequent bubbles and has feedback on the overall flow regime. In this study, ultrafast X-ray tomography was used to investigate the inter-bubble distances and clustering characteristics in bubbly flows in a lab scale bubble column. It was found that large bubbles exhibited pronounced vertical clustering, while no clustering was observed for bubbles with lower gas holdup. The orientation of clustering primarily depended on the deformability of the bubbles rather than the gas holdup.

Summary: This study used in operando X-ray micro-computed tomography (mu CT) to monitor the progression of the liquid, gaseous, and solid phases of silica gels during ambient pressure drying and spring-back. The findings challenge the common assumption about the penetration of gas during the spring-back effect and show that the emergence of the spring-back effect is correlated to an equal volume fraction of solid, liquid, and gas in the gels.

Summary: Bubbles and slugs coexist in a fluidized bed with strong inter-particle forces. Different effects on fluidizing stability and chemical reaction efficiency are observed between bubbles and slugs. X-ray tomography is used to distinguish and study the properties of bubbles and slugs in a fluidized bed with varying inter-particle force. The gas-holding capacity of the emulsion phase improves as inter-particle force increases, while the bubble frequency decreases and bubble size slightly increases. Slugs increase in frequency and size with inter-particle forces, and different slugging patterns are identified with varying influences on particle flow.

Summary: In this study, a bubble structure-dependent (BSD) model is implemented to consider the bubble effect in a fluidized bed, where the kinetic theory of rough sphere (KTRS) is incorporated to describe the particle collision effect. The frictional contribution at a high solid concertation is taken into account, where the random fluctuation is introduced in the frictional stress to incorporate the mesoscale effect in the frictional regime. Mesoscale effects on frictional solid stress are analyzed. The results demonstrate that the mesoscale effect in the frictional regime leads to a more intensive fluctuation of the stress. In addition, the effects of particle roughness on frictional solid stress and mesoscale parameters are also discussed.

The results showed that plastic deformations and permeability of coal increased with unloading levels, with a reverse trend when unloading level was large. The experiment also revealed the coexistence of Kaiser effect and Felicity effect, and the relationship between dissipated energy and cycle number shifted from logarithm to linear as unloading levels increased.

Summary: This paper demonstrates that structured reactors operated under gas-liquid Taylor flow can overcome the mass transfer limitations in CO2 electrolysis in aqueous systems and significantly improve reactor performance. By developing an easy-to-use analytical model, the relationship between process conditions, mass transfer, and reactor performance is explored. The results show that the film thickness and the volume ratio of CO2/electrolyte fed to the reactor greatly affect the current density and the faradaic efficiency, and industrially relevant performance can be achieved when operating the reactor at an elevated pressure beyond 5 bar.

Summary: This study investigates the electrochemical CO2 reduction performance of copper in non-aqueous electrolytes based on DMF, NMP, and ACN. The results show that DMF and NMP mainly produce oxalate, while ACN mainly produces hydrogen and formate. Therefore, aqueous electrolytes exhibit higher selectivity for hydrocarbon and alcohol production on copper electrodes, while organic electrolytes based on DMF and NMP are more suitable for obtaining oxalate and formate.

Summary: Coupling the analysis of technical feasibility with economic evaluation is crucial in identifying targets for development in electrochemical CO2 conversion processes. Electrochemical conversion of captured CO2 to base chemicals has the potential to contribute to a sustainable energy transition by closing the carbon cycle. While low-temperature electrochemical CO2 conversion has been demonstrated at lab scale, optimizing electrolyzer design and operation for industrial applications based on techno-economic analysis is the current focus. However, existing analyses often overlook the interdependencies between key performance variables, such as current density, Faradaic efficiency, and conversion. Our study highlights the significance of multiscale models in the field of CO2 electrolysis to understand the economic trade-offs and overcome bottlenecks in system designs.

Summary: The promotional effects of ALD-deposited CuxO clusters on photocatalytic hydrogen production on P25 TiO2 were studied. It was found that the strong interaction between CuxO and TiO2 resulted in the stabilization of CuxO clusters on the surface. The CuxO/TiO2 photocatalysts showed remarkable improvement in hydrogen productivity, which can be attributed to increased charge carrier separation, improved light absorption, and the generation of surface Ti3+.

Summary: This study focused on the semihydrogenation of acetylene in an ethylene-rich stream using two alloyed Pt catalysts PtCu and PtCo. The PtCu catalyst showed higher activity and ethylene yield compared to PtCo due to its higher unoccupied Pt d-orbital density.

Summary: This work presents a continuous solvent extraction method for the separation of cobalt and nickel in a millifluidic system using Cyphos IL 101 (C101) as the extractant. The optimal conditions for extraction performance and solvent properties were determined by investigating the effects of channel length, flow rate, and temperature. The performance of a developed manifold structure was compared to a single-channel system, and excellent separation results were achieved. The continuous separation process using the manifold structure resulted in high purity cobalt and nickel products.

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.
