This study systematically investigated the hydrodynamic and liquid–liquid dispersion characteristics of the MARB, including residence time distribution, liquid holdup, energy dissipation rate, and Sauter mean diameter (d32). Mathematical correlations for predicting these parameters were established. The results showed that the MARB operates with a flow pattern similar to that of a continuous stirred-tank reactor. Liquid holdup increased linearly with flow rate and decreased with rotational speed, while energy dissipation rate was primarily governed by rotational speed. Notably, the MARB demonstrated excellent liquid–liquid dispersion performance, attaining a minimum d32 of 4.9 μm at a flow rate of 5 L/min, along with improved energy efficiency compared to conventional reactors. With its simple, high-throughput, and effective design, the MARB offers a highly promising solution for efficient liquid–liquid dispersion in industrial applications.","PeriodicalId":120,"journal":{"name":"AIChE Journal","volume":"17 1","pages":""},"PeriodicalIF":3.7,"publicationDate":"2025-06-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144252861","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Herein, a polyoxometalate (POM) species, phosphomolybdic acid hydrate (PMA, H3PMo12O40) was stably integrated into the nanocages of an ionic COF (EB‐TFP). Considering practical applications, the resulting composite (EB‐TFP/PMA) powder was shaped into monolithic pellets with sufficient crushing strength and thermal stability. These materials were used in a one‐pot reaction of CO2 and olefins to obtain value‐added cyclic carbonates. Detailed activity evaluations revealed that the excellent catalytic performance (90% of main yield under the conditions of 80 C, 1 bar, 24 h and no co‐catalysts) of EB‐TFP/PMA arose from the synergistic effect of acid/base sites. The pellets also showed satisfactory catalytic performance (83% of yield under the same conditions) and good reusability. This study highlights the potential of COFs as platforms to construct synergistic active sites tailored for one‐pot catalysis.","PeriodicalId":120,"journal":{"name":"AIChE Journal","volume":"36 1","pages":""},"PeriodicalIF":3.7,"publicationDate":"2025-06-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144228673","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Precise nanochannel manipulation of laminar‐structured COF membranes is of critical significance. In this study, COF membranes are engineered by assembling COF‐TbTG nanosheets and sulfobutylether‐β‐cyclodextrin (SCD) into laminar structures. The interlamellar spaces of COFs are regulated to achieve molecular sieving for precise separation; the intrinsic pores of COFs are utilized as fast molecule‐transport channels. The obtained COF membranes exhibit a superior ethanol dehydration performance with a permeation flux of 5.2 kg m−2 h−1 and a separation factor of 1072, which exceeds the performances of state‐of‐the‐art membranes for water/ethanol separation. Moreover, the optimal membranes show a steady permeation flux maintaining around 5.0 kg m−2 h−1 during a 72‐h operation test.

Traditional viscosity measurements are labor-intensive and time-consuming due to numerous influencing factors. This study introduces a novel prediction framework integrating message passing neural networks (MPNN)-graph attention networks (GAT)-multilayer perceptron (MLP). Using a dataset of 5790 DESs, recognizing the essential role of SMILES in predicting DESs viscosity, two stacked GAT layers were utilized to implicitly capture interdependencies among molecular substructures, enabling the extraction of significant features. Given that DESs are typically binary systems, the predicted density is incorporated as an additional input, reducing reliance on experimental data. The MLP combines these extracted features with physical and chemical properties for accurate viscosity prediction. This multiscale, data-driven approach significantly improves prediction performance (R2 = 0.9945, AARD = 2.69%), surpassing conventional methods and advancing green solvent design.","PeriodicalId":120,"journal":{"name":"AIChE Journal","volume":"10 1","pages":""},"PeriodicalIF":3.7,"publicationDate":"2025-06-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144229226","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Hence, this study employs microwave technology to intensify the extraction process using Ag-based ionic liquid (Ag-IL), where the influence of microwave irradiation and the mechanism of microwave-assisted ionic liquid extraction (MAILE) are investigated, along with a comprehensive techno-economic analysis of process feasibility. The results of COSMO-RS and DFT simulations demonstrate the dominant role of π-complexation in identifying Ag-IL with high selectivity, indicating the possible enhancement caused by microwave irradiation. The subsequent kinetic experiments show that compared with conventional routes, the MAILE accelerated the extraction process by approximately 89.72%. As a result, the total annual cost of unit product of the overall process is reduced by 6.43% according to techno-economic analysis by Aspen Plus, indicating that MAILE is a cost-effective, scalable, and sustainable approach to α-olefin separation, offering process efficiency and environmental sustainability.","PeriodicalId":120,"journal":{"name":"AIChE Journal","volume":"9 1","pages":""},"PeriodicalIF":3.7,"publicationDate":"2025-06-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144192682","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this paper, Ag+ is used as the coordinating metal, and , which has a weak interaction with it, is selected as the anion. Based on the interaction between the carbonyl oxygen and −NH2, propionamide is selected as the organic ligand. Thus, a deep eutectic solvent of [AgNTf2:2propionamide], with a competitive coordination mechanism for the efficient separation of olefins, was proposed. For the 1‐hexene/hexane, the selectivity is up to 215.24, and the olefin removal rate of single‐stage extraction is up to 90.55%. Using ESI‐MS and XAFS, combined with experimental and calculations, the mechanism of competitive coordination and the coordination structure of C2‐Ag‐O2 were revealed. This solvent can be used to effectively separate olefins from simulated oil, as well as effectively extract and separate unsaturated hydrocarbons such as aromatics/alkanes.","PeriodicalId":120,"journal":{"name":"AIChE Journal","volume":"36 1","pages":""},"PeriodicalIF":3.7,"publicationDate":"2025-05-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144165129","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
