Although various methods are proposed to address plastic waste, the strong carbon–carbon bonds within polyolefins, as well as the degradation of mechanical strength and additional value by conventional recycling methods, pose great challenges to their downstream usage. With this regard, this paper emphasizes the chemical recycling of polyolefins into renewable resources, including carbon materials, liquid fuels, and various hydrocarbon chemicals, by thermal catalytic methods. An in-depth discussion on the feasibility and limitations of promising chemical recycling techniques is provided, such as the association between the reactor design, process optimization, catalyst preparation, and the product distribution. Specifically, the structure–function relationship over different catalysts was highlighted, including the molecular sieve, precious metal, transition metal, and ion liquid. In addition, the future challenge regarding the simultaneous treatment of mixed plastics is also summarized, along with the copyrolysis of waste plastic and biomass. As such, this paper underscores sustainable and scalable solutions for polyolefin upcycling, which may shed light upon the industrial application of plastic resources.","PeriodicalId":39,"journal":{"name":"Industrial & Engineering Chemistry Research","volume":"131 1","pages":""},"PeriodicalIF":4.2,"publicationDate":"2025-03-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143546963","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}

This paper investigates the dynamic behavior of bubble growth on porous surfaces by establishing a transient fluid continuum surface force (VOF-CSF) model, emphasizing how wettability and surface microstructure influence bubble dynamics with specific wettability and microcavity configurations. The results indicate that the adhesion effect associated with hydrophobic surfaces leads to bubbles primarily expanding in the horizontal direction, thereby facilitating their merging with adjacent bubbles. As for smooth hydrophilic porous surfaces, there exists a clear microlayer liquid film between the bubbles and particles and replenishes the liquid supply. While, the microcavity structures generate numerous vortices at the bottom of the liquid film that significantly disturb the vapor–liquid interface and significantly enhance bubble departure; additionally, the liquid film within these microcavities provides an effective rehydration pathway. Furthermore, the microclusters induced by the fluid continuously interact with the bubble boundary, significantly enhancing the growth behavior of the bubbles. This interaction results in an increase in the bubble growth rate by 30–40% and improves heat transfer performance within porous structures by 23%.","PeriodicalId":39,"journal":{"name":"Industrial & Engineering Chemistry Research","volume":"99 1","pages":""},"PeriodicalIF":4.2,"publicationDate":"2025-03-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143539132","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}

Nevertheless, the conventional covalent cross-linking network inherently restricts its recyclability and reprocessability, leading to substantial resource depletion and considerable environmental degradation. Herein, we present an efficient strategy for the fabrication of high-performance and recyclable SBR materials based on ionic cluster interactions. The commercial SBR is brominated to establish dynamic ionic cluster cross-linking networks with 4-(alkylamino)-pyridine (DMAP) under simple hot pressing condition. Owing to the electron-donating characteristics and resonance-induced isomerization of DMAP, the SBR obtained in this study attains a markedly elevated tensile strength of 12.0 MPa and a toughness of 48.9 MJ/m3, both of which outperform those of conventional sulfur-vulcanized SBR. Furthermore, the developed SBR materials exhibit outstanding reprocessability due to their effective reversibility of dynamic bromine-DMAP ionic cluster cross-linking, endowing the rubber materials with good recyclability. This study proposes an effective methodology for the fabrication of high-performance, recyclable elastomeric materials, paving a promising path for the sustainable advancement of the rubber industry.","PeriodicalId":39,"journal":{"name":"Industrial & Engineering Chemistry Research","volume":"84 1","pages":""},"PeriodicalIF":4.2,"publicationDate":"2025-03-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143546970","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, we explored an orifice-modified MOF-on-MOF bilayer membrane prepared by growing an amino-functionalized ZIF-7 layer on a ZIF-90 layer through an aldehyde-amine condensation reaction. Due to the precise docking between the aperture windows of the crystal cells of such two MOFs, the size-sieving effect was intensified for selective He separation. The resultant membrane exhibits significantly increased selectivities for He/N2 and He/CH4 along with a satisfactory He permeance (∼67 × 10–10 mol·m–2·s–1·Pa–1). Specifically, the He/N2 selectivity of the membrane can reach 16.19, which is about 5 times higher than that of the ZIF-90 membrane (3.24), ranking among the reported He-selective MOF membranes. In addition, a continuous operation for 100 h, subjected to a successive test at room temperature and 150 °C indicates that the membrane has excellent stability. The proposed concept of orifice-modified MOF-on-MOF would provide a new idea for the design and development of advanced MOF-based gas separation membranes.","PeriodicalId":39,"journal":{"name":"Industrial & Engineering Chemistry Research","volume":"32 1","pages":""},"PeriodicalIF":4.2,"publicationDate":"2025-03-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143546964","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}

Analyzing CRNs of a reactive system requires kinetic data that are typically obtained by time-consuming experiments or computational chemistry. Machine learning (ML) has emerged as a promising approach for rapid property prediction based on historical data. However, the accuracy of ML model predictions in kinetics remains a limitation for their application in CRN analysis. In this study, we integrate the cross-attention mechanisms in neural networks and CRN sensitivity and uncertainty analysis to enable the practical application of the ML models in reliable gas-phase CRN analysis. Specifically, a message-passing neural network (MPNN) architecture along with a cross-attention mechanism (CA-MPNN) was developed for accurate prediction of the reaction rate constants with prediction uncertainty. CA-MPNN model outperformed the conventional deep neural network architectures on most of the reaction property data sets. We combined reaction network sensitivity analysis and ML prediction uncertainty analysis to identify influential reactions with high-level uncertainty of the predicted rate constant, which are further calibrated using high-accuracy quantum chemistry methods to mitigate the problem of inaccurate machine learning predictions. Compared with the traditional workflow, this framework significantly reduces up to 80% computational cost to construct a reliable CRN in the demonstrated gas-phase pyrolysis and combustion applications.","PeriodicalId":39,"journal":{"name":"Industrial & Engineering Chemistry Research","volume":"53 1","pages":""},"PeriodicalIF":4.2,"publicationDate":"2025-03-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143539238","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}

A falling film melt polycondensation reactor model was established and used to simulate the production process of industrial-grade PET, and the process was verified in production. On this basis, two new process designs were implemented to produce both clothing-grade and industrial-grade PET. Due to the efficient mass transfer of the falling film reactor, properties such as the molecular weight and terminal carboxyl content of products were improved, along with an increase in production efficiency. The clothing-grade PET production with a falling film reactor reduced electricity consumption by 10–20%. When dual falling film reactors in series replaced the solid-state polycondensation process, the energy and water consumption dropped to surprisingly low levels owing to the elimination of several production stages.","PeriodicalId":39,"journal":{"name":"Industrial & Engineering Chemistry Research","volume":"16 1","pages":""},"PeriodicalIF":4.2,"publicationDate":"2025-03-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143538735","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}
