However, the poor compatibility with asphalt and high viscous flow temperatures (<i>T</i>_fs) of conventional PUs impede their application in asphalt. Herein, disulfide is used as the chain extender to design a dynamic PU, achieving a PU-asphalt with ultrahigh performance. The flexibility of the disulfide bond improves the compatibility of PU with asphalt, and the tensile strength and elongation at the break of this PU-asphalt are 8.3 MPa and 948.6%, respectively, surpassing most reported PU-modified asphalts. Meanwhile, this PU-asphalt has a moderate <i>T</i>_f of 128.8 °C due to the dynamicity of the disulfide bond. This not only provides remarkable high-temperature performance but also enables processing at moderate temperatures. Additionally, this PU-asphalt exhibits outstanding low-temperature performance, owing to the flexibility of the PU molecules.","PeriodicalId":39,"journal":{"name":"Industrial & Engineering Chemistry Research","volume":"37 1","pages":""},"PeriodicalIF":4.2,"publicationDate":"2025-05-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144067422","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}

But this is not always possible due to demand variations. Therefore, the operator decides the treatment stages based on the plant capacity and switches from one stage to another when demand changes. This study proposes a mixed-integer programming approach to minimize such switches while ensuring water quality and satisfying drinking water tank capacity constraints. Considering daily operations, time-dependent binary variables are used to describe the hourly treatment quantity, resulting in a mixed-integer linear programming (MILP) problem. The proposed approach is verified in an industrial treatment plant. Compared with conventional operations, the number of switches can be reduced by about 30% through the optimization.","PeriodicalId":39,"journal":{"name":"Industrial & Engineering Chemistry Research","volume":"125 1","pages":""},"PeriodicalIF":4.2,"publicationDate":"2025-05-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143979704","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}

Conventional methanol production involves high-temperature reforming/gasification of natural gas, coal, and biomass, followed by high-pressure catalytic synthesis, resulting in substantial energy consumption. To address this issue, a novel multifunctional WO_<i>x</i>–Cu/TiO₂–Al₂O₃ (W–Cu–TiAl) catalyst was developed in this work that allows cellulose to be directly converted into methanol in a one-pot process. It was demonstrated that the loading of tungsten greatly improved the catalytic activity of the copper-based catalysts, allowing the cellulose to yield 51.6% methanol by reacting at 250 °C for 10 h. The catalysts were further characterized by X-ray diffraction (XRD), high-resolution transmission electron microscopy (HR-TEM), Brunauer–Emmett–Teller analysis (BET), X-ray photoelectron spectroscopy (XPS), and temperature-programmed desorption of ammonia (NH₃-TPD) to reveal the possible catalyst structure–reactivity relationship. It was found that the introduction of tungsten not only reduced the total acid concentration of the catalyst but also slightly increased the binding energies of Cu 2p_3/2 and Cu 2p_1/2, which may be related to the increase in methanol yield. This work provides a new approach to cleaner production of methanol.","PeriodicalId":39,"journal":{"name":"Industrial & Engineering Chemistry Research","volume":"52 1","pages":""},"PeriodicalIF":4.2,"publicationDate":"2025-05-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143979565","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}
