A catalytic membrane reactor (CMR) that integrates the reaction with a Ru (10 wt%)/Cs/MgO catalyst and the membrane separation with a sulfonated (3-mercaptopropyl)trimethoxysilane (MPTMS) membrane in one unit was used for green NH3 production at 300°C and 200–300 kPa. Consequently, the NH3 mole fraction was greatly increased to 0.031–0.046 in the permeate side of the membrane, which is 10 times higher than 0.0028–0.0039 in a packed bed reactor, together with an improved conversion from ~0.5% to 6%–9%. Process simulation of the CMR was formulated, confirming that the simulated performance agreed with experiments. Process simulation and experimental results show that increasing the feed pressure and flow rate would decrease the NH3 molar fraction in the permeate side of the membrane and conversion, since high pressures promote H2 and N2 permeation more than NH3.","PeriodicalId":120,"journal":{"name":"AIChE Journal","volume":"21 1","pages":""},"PeriodicalIF":3.7,"publicationDate":"2025-04-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143837172","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 the present work, a mixed absorbent comprising diethanolamine (DEA) and polyethylene glycol 200 (PEG200) with high thermal stability and low specific heat capacity was designed for CO2 absorption. Absorption capacity was measured at different temperatures and pressures; the first-order kinetic and bimolecular reaction thermodynamic models were also developed, and relative parameters were obtained. An optimal simulation of the absorption process was carried out. Based on the optimal control (OC) theory and kinetic parameters, the optimal absorption temperature of the absorption process at a certain fixed time was obtained, which decreases with the increase of time. Moreover, the optimal absorption temperature curve can further enhance the absorption capacity. Furthermore, an entropy–enthalpy compensation phenomenon was found for the capture of CO2 with different absorbents.","PeriodicalId":120,"journal":{"name":"AIChE Journal","volume":"40 1","pages":""},"PeriodicalIF":3.7,"publicationDate":"2025-04-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143832278","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, the heteroenergetic dual-supports were prepared by coating resorcinol-formaldehyde (RF) resin on mesoporous SBA-15 to regulate the growth and surface microenvironment of Pd. After calcination and reduction, phenolic hydroxyl groups in the residual carbon layer effectively reduced the Pd particle size, induced the formation of adjacent Pd0–Pdδ+, and created hydrophobicity. Density functional theory calculations revealed that Pd atoms preferentially interact with OH on C, rather than with OH on SBA-15, providing an intrinsic driving force for smaller Pd particle size. The mass ratio of RF to SBA-15 was shown to be a crucial parameter affecting the catalytic performance. At the ratio of 4 (carbon content of 2.02%) the catalyst possesses the smallest Pd particles, 30% Pdδ+ proportion, and higher hydrophobicity, achieving the best catalytic performance, with an activity of 0.57 molH2·gPd−1·min−1 and a selectivity of 95.3%.","PeriodicalId":120,"journal":{"name":"AIChE Journal","volume":"108 1","pages":""},"PeriodicalIF":3.7,"publicationDate":"2025-04-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143832228","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}

The activity of [N8881]2MoO4 for catalyzing the selective HDO reaction is much better than commercial precursors like Mo(CO)6 and (NH4)6Mo7O24. 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.

Traditional clone selection and process optimization methods are laborious and time-consuming due to multiple iterative rounds. To enhance efficiency, real-time metabolite monitoring and parameter control are vital. We propose an intelligent process development (IPD) platform utilizing Raman spectroscopy-based process analytical technology (PAT) for real-time monitoring and feedback control. The IPD platform automates optimization, incorporating a cell-specific growth rate (μ)-based temperature downshifting strategy and a dynamic feeding approach. Compared to traditional fed-batch (TFB), the IPD strategy increased the clone's titer by 44% (1490 vs. 1034 mg/L). To meet large-scale manufacturing demands, we adapted the Raman-based IPD process into a TFB process with comparable titer, compatible with facilities lacking PAT or automation. This approach was validated with an alternative clone, demonstrating the IPD's ability to enhance productivity through a single automated round, accelerating development.","PeriodicalId":120,"journal":{"name":"AIChE Journal","volume":"71 7","pages":""},"PeriodicalIF":3.5,"publicationDate":"2025-04-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143813943","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 work, a strategy for modulating alkyne adsorption sites by modifying the support is proposed. A series of Pd/ZSM-5@PPh3-X with different coverage of triphenylphosphine (PPh3) were synthesized. Pd/ZSM-5@PPh3-X enable efficient semi-hydrogenation of alkynes under mild conditions. Specifically, the catalyst with lower surface ligand coverage (Pd/ZSM-5@PPh3-2) exhibits a preference for the hydrogenation of 2-methyl-3-butyn-2-ol, while the catalyst with higher ligand coverage (Pd/ZSM-5@PPh3-10) favors the conversion of phenylacetylene. Both catalysts maintain an alkene selectivity exceeding 94%. Comprehensive experimental, characterization, and computational analyses revealed that for 2-methyl-3-butyn-2-ol, which adsorbs on the palladium surface, the PPh3 inhibits the strong adsorption of alkynes, thereby preventing catalyst self-poisoning. Conversely, the high PPh3 coverage redirects the adsorption site of phenylacetylene to the support surface, and the enhanced hydrogen spillover accelerates the reaction. This ligand-modulated strategy offers guidance for the rational design of chemoselective catalysts.","PeriodicalId":120,"journal":{"name":"AIChE Journal","volume":"71 7","pages":""},"PeriodicalIF":3.5,"publicationDate":"2025-04-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143805875","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}
