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 ：
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 ：
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 ：
The water gas shift reaction is an important procedure in high-purity hydrogen production, and achieving high CO conversion in one single reactor is a key optimization objective. This work has developed a novel radial flow fixed-bed reactor for water gas shift reaction with integrated variable heat exchange and numerically investigated the system optimization concepts. The continuous heat removal from the catalyst bed has been proven to fully improve CO conversion at a lower H2O/CO molar ratio. The heat transfer rate distribution can also be flexibly adjusted to ensure sufficiently high and low temperatures in the early and late stages of the reaction, respectively, for a higher conversion. With sufficient coolant, low-temperature and high-temperature catalysts for water gas shift reaction can be combined in one reactor to increase CO conversion to over 98%, and the delayed heat removal configuration can achieve the highest CO conversion (98.50%) with the least proportion of low-temperature catalysts (9.2%).

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 ：
Developing highly efficient catalysts for the transformation of hydrogen sulfide (H2S) pollutants into value-added products is crucial for both fundamental catalytic research and industrial chemistry. Herein, ferrititanate nanosheets (H0.8Ti1.2Fe0.8O4, denoted as NS-HTFO) exfoliated from lepidocrocite-type titanates are employed for the first time to catalyze the conversion of H2S to elemental sulfur. Collective experimental characterizations reveal that the as-designed NS-HTFO catalyst possesses ultrathin 2D structure and a large specific surface area, featuring abundant oxygen vacancies. Compared with its sandwich-like precursor of K0.8Ti1.2Fe0.8O4 (denoted as L-KTFO), the NS-HTFO catalyst displays notably enhanced desulfurization activity, achieving 100 % H2S conversion and over 93 % sulfur selectivity at temperatures ranging from 90 to 270 degrees C. Moreover, no significant decline in sulfur yield is observed over the course of a 100-hour evaluation, showing outstanding breakthrough sulfur capacity up to 4163 mg/gcat. This performance exceeds that of most recently reported catalysts. The possible catalytic mechanism for H2S-to-S selective oxidation over the NS-HTFO catalyst has also been investigated.

Abstract ：
The capture the low-content NH3 from industrial streams, and recycle it as the feedstocks for industrial processes is very important. In this work, we reported the use of mesoporous polydivinylbenzene (PDVB) as the support of metal-based deep eutectic solvents (DESs) containing choline chloride (ChCl) and metal chlorides (SnCl2, FeCl3 or ZnCl2) for NH3 capture. The structure of composite materials was characterized in details, and the NH3 capture performance and mechanism of them were also examined in depth. Owing to the coordination interaction of metal ions with NH3, along with the hydrogen-bond interaction of - OH and Cl- with NH3, the DES@PDVB composites exhibit considerably high low-content NH3 capacities. The optimized sample ChCl + 2ZnCl2@PDVB1.5 can adsorb 7.43 mol/kg of NH3 at 25 degree celsius and 0.122 bar, which is advantageous over most other adsorbents fabricated in the literature. The mechanism of NH3 capture by DES@PDVB composites was also illustrated through spectroscopic characterizations.

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 ：
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 ：
天然气、油田伴生气、高炉煤气等化工生产过程中伴生COS气体，不仅会腐蚀管道和毒害催化剂，还会严重污染环境并危害人类健康。COS催化水解反应可在温和条件下高效的将COS脱除，是最具应用前景的COS脱除技术之一。碱金属元素因其具有独特的电子供体性质、表面碱性和静电吸附等特性，常被用作助催化剂以提高Al_2O_3的COS催化水解性能。近年来，以钾为助剂改性的Al_2O_3催化剂(K_2CO_3/Al_2O_3)在COS催化水解反应中得到广泛的应用，但由于负载在Al_2O_3上的K物种的组成复杂，目前研究者对K_2CO_3/Al_2O_3催化剂上COS水解机理的理解仍存在一定的困惑和争议。本论文通过湿法浸渍法合成出一系列钾盐和钠盐改性的Al_2O_3催化剂，并利用各类先进的表征技术对这些催化剂进行分析。活性测试表明，以K_2CO_3、K_2C_2O_4、NaHCO_3、Na_2CO_3和NaC_2O_4改性Al_2O_3催化剂均有助于COS的水解。其中K_2CO_3/Al_2O_3拥有最佳的COS水解性能，连续运行20 h后其COS转化率仍高于～93%，远远优于未改性的Al_2O_3 (～58%)。我们利用原位红外光谱和X射线光电子能谱探明了反应过程中催化剂的化学结构特征，阐明了H_2O分子在K_2CO_3/Al_2O_3上的水解作用机制。原位红外表明COS在K_2CO_3/Al_2O_3上的水解过程中形成了硫代碳酸氢盐中间产物。X射线光电子能谱表征证明催化剂的失活主要是因为催化剂表面积累了硫酸盐和单质硫。此外，我们还研究了水蒸气含量对COS水解性能的影响，研究发现，由于H_2O和COS分子在催化剂表面存在竞争吸附，过量的H_2O会引起催化活性的下降。上述研究表明，K_2CO_3/Al_2O_3催化剂上COS水解性能的提高主要是形成了HO-Al-O-K界面活性位。更为重要的是，所制备的催化剂都是在模拟工业工况条件下进行的，这为后续的工业应用提供了宝贵理论指导。本工作为理解助剂钾在Al_2O_3催化剂上COS水解活性的增强提供了新的见解，这为未来设计稳定高效的COS水解催化剂打开了新的发展方向。
