Abstract ：
In the present work, the selective hydrodeoxygenation (HDO) performance of stearic acid over in situ MoS2 catalysts produced from various Mo precursors was evaluated. Notably, the in situ MoS2 catalyst generated from [N-8881](2)MoO4-a Mo-based ionic liquid (IL) with oil-soluble property-achieves up to 99.9% of stearic acid conversion with the HDO product octadecane yield of 97.5% at 300 degrees C, 8 MPa, and 6 h. The activity of [N-8881](2)MoO4 for catalyzing the selective HDO reaction is much better than commercial precursors like Mo(CO)(6) and (NH4)(6)Mo7O24. The in situ MoS2 catalysts were thoroughly characterized and analyzed to elucidate the experimental results. Moreover, the reaction pathway of stearic acid was proposed according to the product distribution, and the relative kinetic parameters were also calculated and discussed. The results indicate that applying Mo-based IL as the precursor to generate in situ MoS2 catalyst for the selective HDO of biolipids is highly interesting and desired.

Abstract ：
Developing catalysts enabling reactive separation is a promising strategy to enhance reaction and separation efficiency of esterification processes. Herein, we designed a class of hybrid catalysts with p-toluenesulfonic acid (PTSA) as main catalyst, and hydrogensulfate ILs as support catalyst and extractant. Using the designed catalysts for methyl esterification of long-chain fatty acids, phase splitting can occur, resulting in ester-rich and catalyst-rich phases. Under optimal conditions, the conversion of palmitic acid (PA) gives methyl palmitate (MP) yield of 98.2 % in 3 hat 348.2 K. The catalysts are also applicable for effective conversion of other long-chain fatty acids and can be facilely recycled through liquid-liquid separation without loss of activity. COSMOtherm and Gaussian calculations were performed to rationalize the reactive separation behavior of the designed catalysts. The kinetic and thermodynamic properties of the esterification reaction were also examined using pseudo-homogeneous (PH) model with non-ideality corrections.

Abstract ：
High-carbon alcohols are important chemical raw materials and have extensive applications in the fields of chemistry, chemical engineering, and pharmaceuticals. Converting fatty acids or fatty acid methyl esters from waste oil into high-carbon alcohols through hydrogenation has attracted increasing attention. In this study, a series of Cu-ZrO2 catalysts were prepared by a citric acid-assisted sol-gel method. Results reveal that Cu-ZrO2 catalysts prepared by the sol-gel method mainly exist in the form of tetragonal ZrO2with loaded copper species. There is a certain metal-support interaction between metallic Cu and the ZrO2 support, and ZrO2 crystal phase can be retained during the harsh catalytic reaction conditions. X-ray photoelectron spectroscopy results show that Cu0 species are the key active centers. When the Cu0 content is insufficient, the conversion rate of methyl palmitate increases with the increase of Cu0 content. When the Cu0 content is sufficient, Cu+ and Cu0 have a synergistic effect on the hydrogenation reaction. Catalyst dosage, reaction time, reaction temperature and hydrogen pressure were found to have significant effects on the catalytic transformation of methyl palmitate. Increase of reaction temperature can significantly improve the conversion of methyl palmitate. However, excessive temperature can easily induce the dehydration of the generated hexadecanol into by-products such as hexadecane. The conversion of methyl palmitate can be up to 95.1%, and the yield of hexadecanol can reach 91.1% under the conditions of 10% copper loading, 300℃, 6MPa H2 pressure and 2h reaction. © 2025 Chemical Industry Press Co., Ltd..

Abstract ：
The efficient deoxygenation of renewable biolipids into liquid alkanes within the diesel range is a key protocol for producing high-quality biofuels. In this work, the conversion of methyl palmitate and raw palm oil were accomplished utilizing a bifunctional catalyst of Ni catalysts supported on B2O3-ZrO2 under solvent-free conditions. Among various Ni loading ratios investigated, the catalyst featuring a 10 % Ni loading achieved 100 % conversion of methyl palmitate and 84.4 % of liquid yield, with approximately 65 % being C15 alkanes. Additionally, more than 91 % of hydrocarbons were also generated from raw palm oil. These results can be attributed to the synergistic interplay between the acid sites, following B2O3 modification, and the presence of Ni species. Furthermore, the analysis of product distribution, gas product detection and the kinetics calculation strongly supports that the deoxygenation process of methyl palmitate primarily follows the hydrodecarbonylation route, leading to the predominant formation of C15 alkane.

Abstract ：
The design of novel practical catalysts is critical for the blossoming of biodiesel green-energy, in which Mo-based catalysts are of particular interest. In this work, an in-situ synthesis method was proposed to obtain a combo Mo-based ionic liquid and SAPO-11 catalyst. The catalyst presents both highly dispersed MoS2 as hydrodeoxygenation active sites and acidic sites for isomerization. MoS2 with a few fine layers can be identified based on TEM images and the Bronsted acid sites are dominant based on Pyridine-IR analysis. A great performance of MoS2/C(8)min-15 %SA can be obtained under optimized reaction conditions with 100 % conversion of methyl palmitate, 75.0 mol% hydrodeoxygenation to n-C-15-C-16, and 20.5 mol % isomerization to i-C-15-C-16. The structure and activity of the catalyst can be retained at least for 4 cycles. Thin layers and high sulfurization, large amount of Br & oslash;nsted acid sites, and suitable reaction conditions are key points to achieve a significant performance and avoid over cracking and deactivation. On basis of detected intermediates and kinetic data simulations, a complex reaction pathway was proposed and the specific k values for each elementary reaction were provided for the hydrodeoxygenation and isomerization of methyl palmitate.

Abstract ：
There is a particular demand to explore low-volatility and structurally tunable absorbents for efficiency, selectivity and reversibility in capturing H2S. For the first time, the performance of deep eutectic solvents (DESs) composed of 1-ethyl-3-methylimidazolium chloride ([Emim]Cl) and acetamide (AA) were examined as physical absorbents for H2S capture. The physical properties of [Emim]Cl-AA DESs, and solubilities of both H2S and CO2 in them were measured. Relevant experimental results demonstrated that the solubilities of H2S in [Emim]Cl-AA DESs (1.1 mol/kg at 298.2 K and 1.023 bar) significantly exceed those of CO2 (0.040 mol/kg at 298.2 K and 1.027 bar). [Emim]Cl-AA DESs exhibit higher H2S solubilities and superior ideal H2S to CO2 selectivities (e.g., the ideal H2S/CO2 selectivity of [Emim]Cl-AA (1:0.5) is 28.5 at 298.2 K) than those physical absorbents ever reported. The recyclability of [Emim]Cl-AA DESs for H2S selective capture was also evaluated, which was found to be very stable in ten continuous absorption and regeneration cycle experiments. The mechanism of H2S capture by [Emim]Cl-AA DESs was finally illustrated at the molecular level with the support of theoretical calculations.

Abstract ：
This study explored diethanolammonium chloride ([DEA]Cl) as a potential ionic liquid from low-cost and commercial ones for gas separation. There are three kinds of functional sites in [DEA]Cl: acidic -NH2+, hydrogen-bond -OH, and nucleophilic Cl-. The separation of NH3/N-2/H-2, SO2/CO2/N-2, and H2S/CO2/CH4 was considered, because the three mixtures are extensively involved in many industrial processes. The experimental results demonstrated that [DEA]Cl exhibited excellent ability to separate the mixture of NH3/N-2/H-2. The [DEA]Cl also exhibited the proper capacity to separate SO2/CO2/N-2, but the capacity of [DEA]Cl for the separation of H2S/CO2/CH4 was inferior. The theoretical calculations revealed that -NH2+ and -OH worked synergistically to contribute to the ability of [DEA]Cl for excellent separation of NH3 from NH3/N-2/H-2, with Cl- contributing to the proper separation of SO2 from SO2/CO2/N-2. This study provides experimental and theoretical basis for the industrial application of [DEA]Cl in the area of gas separation.

Abstract ：
Renewable fatty esters are a class of clean feedstock to produce high value-added fatty alcohols. Herein, the hydrogenation of methyl palmitate (MP) to hexadecanol over defect-rich Cu/m-ZrO2 catalysts was studied systematically. A series of Cu/m-ZrO2 catalysts with different concentrations of oxygen vacancies (Ovs) were fabricated by adjusting the calcination temperature of m-ZrO2 support. Among the catalysts, Cu/m-ZrO2-350 displays the highest Cu dispersion, the largest number of Cu0 sites and surface Ov concentration, which exhibits the best activity for MP hydrogenation. It gives the MP conversion of 94.6% and hexadecanol yield of 93.3% at 300 degrees C and 7.5 MPa of H2. Spectroscopic characterizations and theoretical calculations revealed that the highly dispersed Cu species and abundant Ov sites synergistically boost the hydrogenation of MP. Specifically, the Cu0 sites facilitate the heterolysis of H2, and the Ov sites contribute to the dissociation of MP. The synergistic effect of Cu species and Ov sites disclosed in this work provides deep insights into the design of catalysts for efficient conversion of fatty esters to fatty alcohols.
