Herein, we customize the pore environments with versatile and dense adsorption sites in a novel interpenetrated adsorbent, Zn-mtz-ina, to simultaneously remove C2H2, CO2, and C2H6 from C2H4. As a result, Zn-mtz-ina exhibits benchmark adsorption capacity for C2H2 (3.01 mmol g−1) and IAST selectivity for C2H2/C2H4 (4.7), along with a low C2H4 uptake (1.60 mmol g−1) among reported similar adsorbents. Dynamic breakthrough experiments confirm the direct production of polymer-grade C2H4 (>99.9%) from a C2H2/C2H6/CO2/C2H4 (1/33/33/33, v/v/v/v) gas mixture with a high productivity of 0.36 mmol g−1 under ambient conditions.

Synthesizing end‐to‐end optimal (E2EO) manufacturing routes is crucial for the pharmaceutical industry, especially when considering multiple operating modes—such as batch, continuous, or hybrid (containing both batch and continuous steps). A major challenge is the ability to compare these manufacturing alternatives across different operating modes, hindering optimal superstructure synthesis. To bridge this gap, this study introduces a hierarchical framework for the synthesis of E2EO manufacturing routes, employing a hybrid rule‐based and optimization‐driven approach. This method optimizes flowsheets modeled using PharmaPy through a simulation‐optimization technique with modest computational requirements. The effectiveness of the proposed framework is demonstrated through a case study on the manufacturing of the cancer therapy drug Lomustine. Two distinct manufacturing scenarios are analyzed to generate E2EO manufacturing campaigns tailored to the specific chemistries and process configurations, considering process efficiency and sustainable manufacturing.","PeriodicalId":120,"journal":{"name":"AIChE Journal","volume":"42 1","pages":""},"PeriodicalIF":3.7,"publicationDate":"2025-05-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144066007","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 in situ infrared (IR) spectroscopy and molecular dynamics (MD) simulation demonstrated that the hydrophobic surface repels water at the electrode interface, significantly reducing its local concentration. The biphasic electrochemical device is promoted by surfactants. Transmission electron microscope (TEM) and dynamic light scattering (DLS) confirmed the formation of reverse micelles in the organic layer, which encapsulates water-soluble reactants to enhance mass transfer.

Catalyst characterization illustrated that the formation of MgCr2O4 spinel, which restrained the generation of NiMgO2 solid solution and increased the concentration of Ni0 species, along with the surface electron effect between Ni0 and Cu+, contributes to this superior hydrodeoxygenation performance of lignin. Mechanistic investigation further demonstrated that the conversion of lignin to 4-ethylcyclohexanol involves a tandem process of Cβ–O bonds cleavage, demethoxylation, and saturated hydrogenation.

Pd-containing materials have been proven to be effective catalysts, while balancing the activity-selectivity trade-off remains a significant challenge. Here we report the fabrication of Pd single atoms from the conversion of metal–organic polyhedra (MOPs) for the first time. The MOP (M6L4), constructed from Pd salt and N-containing ligand, can interact with the graphene support via π-electron coupling, leading to well dispersion of MOP molecules. In subsequent thermal treatment, Pd is anchored by N-doped graphene formed in situ, producing single Pd atoms (denoted as Pd1/G). The obtained Pd1/G catalyst exhibits excellent activity (100% conversion) and styrene selectivity (94%) in the semi-hydrogenation of phenylacetylene under mild conditions (298 K, 1 bar H2). Such performance is much superior to the counterpart catalyst Pd/G with Pd nanoparticles and the commercial Lindlar catalyst and is among the best of the reported catalysts for phenylacetylene semi-hydrogenation.","PeriodicalId":120,"journal":{"name":"AIChE Journal","volume":"67 1","pages":""},"PeriodicalIF":3.7,"publicationDate":"2025-05-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143940246","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}

However, the limited catalytic activity and cycling stability of catalysts under high–temperature alkaline conditions hinder their industrial application. Herein, zirconium hydrogenphosphate (ZrHP) catalysts, featuring abundant acidic sites, were first utilized for amine solution regeneration. By leveraging its proton donation and acceptance mechanism, efficient monoethanolamine solution regeneration was achieved. The ZrHP–4 catalyst demonstrated a 526% increase in the instantaneous CO2 desorption rate compared to the non–catalytic test, reducing the relative heat duty by 48%. Moreover, ZrHP–4 exhibited remarkable stability over 10 cycles without requiring regeneration. Density functional theory calculations revealed that ZrHP promotes CO2 desorption by elongating the C—N bond of carbamate and lowering the proton transfer energy barrier. Therefore, this study offers novel insights into the design and mechanistic understanding of efficient and stable catalysts for amine solution regeneration.","PeriodicalId":120,"journal":{"name":"AIChE Journal","volume":"124 1","pages":""},"PeriodicalIF":3.7,"publicationDate":"2025-05-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143940247","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}
