Summary: The use of lignocellulosic biomass as raw materials for the production of biofuels is increasing. Reliable kinetic models are needed for the shift from lab-scale to industrial scale. We developed and assessed several kinetic models for the hydrogenation of butyl levulinate to γ-valerolactone over Ru/C in different thermal modes. The most reliable models were found to be the non-competitive Langmuir Hinshelwood with hydrogen non-dissociation and dissociation.

Summary: The addition of β-valerolactone (GVL) co-solvent during the acid-catalyzed conversion of cellulose in ethanol improves the reaction rate and catalytic activity for producing ethyl levulinate (EL). GVL not only aids in the dissolution and depolymerization of cellulose, but also enhances the acidity and catalytic activity of the Al species, resulting in higher yields and faster reaction rates for EL production.

Summary: Developing non-noble metal catalysts with high activity and selectivity for biomass conversion is important yet challenging. In this study, a series of Ni-xP/Al2O3 catalysts with different P/Ni molar ratios were prepared for the conversion of ethyl levulinate to gamma-valerolactone. The developed Ni-0.38P/Al2O3 catalyst exhibited 5.4 times higher activity than the conventional Ni/Al2O3 catalyst and outperformed existing non-noble metal catalysts. The unique catalytic performance was attributed to the formation of Ni3P phase, as identified through various characterizations.

Summary: Ni-based and Ru-based catalysts were compared for the production of gamma-valerolactone from levulinic acid and esters, with optimal performance of tiny nickel particles. Reaction conditions and media significantly influenced substrate reactivity, with Ni catalyst showing best results in 2-propanol. Stability was observed after 3 cycles for both Ni and Ru catalysts, while the use of metallic Zn for hydrogen supply in aqueous medium was deemed unsuitable due to lack of stability.

Summary: This study investigates the mechanism of the conversion of methyl levulinate (ML) to gamma-valeriolactone (GVL) catalyzed by Al(OiPr)(3). The researchers found that the ring-closure step is the rate-determining step and that Al(OiPr)(3) can effectively catalyze the ester exchange reaction. These findings provide insights into the conversion mechanism of ML to GVL and can aid in the design of more efficient catalysts for biomass conversion chemistry.

Summary: In this study, a solvent-free hydrogenation method for the conversion of butyl levulinate (BL) to γ-valerolactone (GVL) and 1,4-pentanediol (1,4-PDO) was reported. The skeletal Cu-Al-Zn catalyst, prepared by alkali leaching, showed irregular micrometer-scale particles with a rough surface. Under constant hydrogen pressure, the catalyst exhibited excellent performance with a 100% LA conversion, 74.75% GVL yield, and 25.63% 1,4-PDO yield. The catalyst also demonstrated stable performance and could be reused up to 5 times without significant activity loss. The presence of Zn in the stable hydrogen pressure suppressed the dehydration of 1,4-PDO.

Summary: The efficient production of GVL from renewable lignocellulose conforms to the principles of circular economy. Catalytic transfer hydrogenation (CTH) of levulinic acid and/or its esters to GVL is a milder route compared to direct hydrogenation. The encapsulation of phosphotungstic acid in UiO-66 (Zr) channels as a bifunctional catalyst improved the catalytic performance in the CTH process.

Summary: Solvent innovation is crucial for enhancing the sustainability of chemical processes. Deep eutectic solvents (DESs) have emerged as environmentally friendly alternatives to toxic and volatile solvents. In this study, hydrophobic DESs derived from lignin were synthesized and their physicochemical properties were characterized. The DESs showed promise as green solvents due to their low viscosity and environmentally friendly constituents. Liquid-liquid extraction experiments revealed high extraction efficiency for biofuel fermentation products using specific DES compositions. Molecular dynamic simulations provided insights into the DES molecular interactions and formation mechanism. This work highlights the potential of lignin-derived hydrophobic DESs as sustainable extraction media.

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.
