Summary: Temperature has a significant effect on adsorption processes, particularly on adsorption equilibrium. While the effect of temperature on adsorption kinetics has been less explored, likely due to a lack of a simple and suitable kinetic model. This study analyzed kinetic data using the Elovich equation and found that most adsorption processes had an activation energy in the range of 12.1 to 25.6 kJ mol(-1).

Summary: In this study, mass transfer enhanced CaO pellets were prepared by utilizing CO2 evacuation to form channels, which significantly improved the initial stage of CO2 sorption and accelerated the sorption kinetics. The enhanced mass transfer not only increased the CO2 sorption uptake at different temperatures, but also had a positive effect on CO2 release after capture. The fast CO2 sorption and regeneration kinetics of the new pellets significantly enhanced the energy efficiency of continuous CO2 capture processes.

Summary: This study synthesized sulfonated polymer resins based on styrene and TMPTA and assessed their catalytic efficiency in glycerol acetylation. A factorial design was employed to study the effects of cross-linker percentage and cross-linker feed time. Lower cross-linker percentages resulted in higher catalytic efficiencies, and there was a linear correlation between catalytic efficiency and cross-linker percentage. Statistical and kinetic models were developed to represent the experimental results and support resin formulation improvement strategies. The TMPTA feed time positively influenced catalytic efficiency, indicating the importance of resin micro- and macrostructure.

Summary: The microporous bioderived Al dicarboxylate MIL-160(Al) MOF in its shaped form has shown potential as a candidate for biogas upgrading (BU) and/or carbon capture and storage (CCS). The adsorption isotherms of CO2, CH4, and N2 at different temperatures and pressures were studied, revealing the loading capacities and fitting with the dual-site Langmuir model. Uptake rate experiments and Response Surface Methodology (RSM) were used to calculate the driving force coefficients and maximize selectivity for CO2/CH4 and CO2/N2 mixtures. Breakthrough curve experiments were simulated using ASPEN Adsorption, confirming the potential of MIL-160(Al) for BU and/or CCS applications.

Summary: In the past decades, the flavor industry has increased its investment in research and development to take innovative steps. However, the lack of information about flavored molecules and specific flavoring properties hinders progress in this sector. This study presents the use of three scientific machine learning techniques as an innovative methodology to design new natural flavor molecules with specific desired properties for product development. The transfer learning technique is utilized to address the lack of available data when analyzing flavor molecules. Nine flavor descriptors were studied, with more than 50% of molecules generated achieving outstanding results in evaluation metrics such as natural product-likeness score and synthetic accessibility score. Finally, a discussion on the results considers data availability, presence in nature, and the impact of multisensory flavor components on specific flavor outcomes.

Summary: Two industrial dual-step pressure swing adsorption (PSA) processes were designed and simulated to obtain high-purity methane, CO2, and syngas from a gas effluent of a CO2 electroreduction reactor using different design configurations. NaX and MFI zeolites were selected from the investigated set for simulation. Case study 1 achieved 90.5% methane purity with a 95.2% recovery, whereas case study 2 obtained methane with a 97.5% purity and 95.3% recovery. Both case studies produced high-purity CO2 (>97%) and syngas with a H-2/CO ratio above 4. However, case study 2 had a significantly higher energy consumption compared to case study 1 (64.9 vs 29.8 W h mol(CH4) (-1)).

Summary: Large amounts of vine shoots generated during vine pruning still contain compounds from the original plant, including phenolic compounds and structural compounds like cellulose, hemicellulose, and lignin. This study proposes the extraction of lignin from vine shoots for the production of nanoparticles, using ethanol/toluene and water/ethanol as solvents. The lignin nanoparticles showed excellent antioxidant properties and the extracts from biomass pretreatment also exhibited antioxidant activity. Overall, this work contributes to the integral reuse of vine shoot byproduct, promoting sustainability.

Summary: Potentially-CO2 adsorbing solids were prepared by calcination of CaAlFe hydrocalumites at 400 and 750 degrees C. The obtained solids were characterized using different techniques, and the CO2 sorption capacity was evaluated under different conditions. The presence of Fe3+ influenced the crystalline phases and the maximum CO2 sorption capacity was achieved when Fe3+ accounted for 40 mol % of the trivalent positions. The steam presence enhanced the CO2 capture during multiple sorption-desorption cycles.

Summary: In this study, nickel-substituted hydrotalcites promoted with cesium were synthesized and their dual-function ability as a high-temperature CO2 adsorbent and methanation catalyst was evaluated. It was found that materials impregnated using the direct impregnation method had a higher number of basic sites, which facilitated greater CO2 sorption. However, these materials exhibited lower selectivity towards methane, resulting in a higher CO formation. Therefore, materials prepared using the powder impregnation method were chosen for further investigation in a parametric study.

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.
