Summary: The study investigated the influence of mass transfer intensity on the kinetics of catalytic oxidation of flax shives to aromatic aldehydes and pulp. It was found that the process was completely diffusion-controlled under the studied conditions, with oxygen transfer being limited by several stages. A simple model connecting mass transfer intensity and stirring power density in the liquid phase was used to describe the results, showing that despite diffusion-controlled conditions, the vanillin yield was close to the theoretical maximum in lignin oxidation processes.

Summary: This study proposes a simple approach to endow epoxy resins (EPs) with excellent flame retardancy and high toughness by combining rigid-flexible groups, promoting groups, and polar phosphorus groups with a vanillin compound. The modified EPs achieve a limiting oxygen index (LOI) of 31.5% and reach V-0 grade in UL-94 vertical burning tests with only 0.22% phosphorus loading. The introduction of the P/N/Si-containing vanillin-based flame retardant (DPBSi) improves the mechanical properties of EPs, including toughness and strength, with significant increases in storage modulus and impact strength.

Summary: The mathematical modeling of the dynamic adsorption of 8-Hydroxyquinoline on activated carbon in batch and fixed-bed adsorbers is described in this study. The model considers mass transport phenomena and includes axial dispersion, convective transport, intraparticle diffusion mechanisms, and adsorption on the active site. A methodology based on adsorption equilibrium and rate studies is proposed to solve the model, without considering fitting the mass transport parameters for breakthrough curve prediction, which is an important advancement in fixed-bed column design. The equilibrium results show that 8-HQ adsorbs onto activated carbon through dispersive and hydrophobic interactions, with a mass adsorbed of 454 mg g-1. The kinetic study reveals that achieving equilibrium is faster under turbulent stirring regime, and intraparticle transport is governed by surface diffusion. By using information obtained from the batch regime, the packed bed behavior can be interpreted and predicted in a wide range of operational conditions with an error of 10.6% in breakthrough point prediction.

Summary: In a simulated moving bed (SMB), regeneration is achieved by using a desorbent and recovering it in downstream separations. The proper selection of an appropriate adsorbent/desorbent pair is crucial for the effectiveness of the SMB process. By developing a parameter called SMB performance indicator (SPI) using readily available literature data, the selection process can be fast and easily accomplished. This metric considers adsorption selectivity, adsorption capacity, and enthalpy ratio, and can determine the most suitable adsorbent/desorbent pair for a specific gas separation in SMB through simple calculations.

Summary: Hardwood vessel elements in wood-free printing paper operation can cause vessel picking and ink refusal, which can be mitigated with mechanical refining but at the cost of paper quality. Enzymatic passivation of vessels through xylanase and cellulase-laccase cocktail treatments improved paper quality by altering vessel adhesion and hydrophobicity. Thermoporosimetry analysis revealed more porous vessel structures, surface analysis showed lower O/C ratio, and bulk chemistry analysis indicated higher hemicellulose content. The enzymatic treatments decreased vessel picking count and reduced water contact angle of fiber sheets compared to vessel-rich sheets.

Summary: Model-based optimization of SMBRs requires efficient solvers and significant computational power. Despite the applications of artificial neural networks (ANNs) in modeling SMB units, their usage in reactive SMBRs is limited. The evaluation of the representation capability of ANNs is an open issue, and the optimal assessment using surrogate models remains unresolved. The main contributions of this study are the optimization of SMBRs based on deep recurrent neural networks (DRNNs) and the characterization of feasible operation regions using metaheuristic techniques. The results show that DRNN-based optimization can effectively address complex optimization problems while achieving optimality.

Summary: In this study, solvent fractionation was used to obtain lignin fractions with a narrowed molecular weight and specific structural characteristics, improving its homogeneity and purity. The water-soluble fraction had more phenolic OH, less aliphatic OH groups, and less aryl-ether linkages, indicating higher condensation degree. On the other hand, the insoluble fraction from the 60% acetone mixture had the lowest molecular weight and highest inorganic material content. The fraction with the highest potential (IF 30:70) showed an increase of about 13% for vanillin and 19% for syringaldehyde after alkaline oxidation, suggesting its potential as a source of high added-value monomeric phenolic compounds.

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.
