However, the RE³⁺ extraction efficiency and selectivity still need to be improved in the adsorption process. Herein, a phosphate functionalization biogenic manganese oxide (PR-BMO) was fabricated by a biomineralization method for effective and selective adsorption of RE³⁺. PR-BMO was a complex of biogenic manganese oxide and Mn₂P₂O₇, which exhibited a stacked lamellar structure, had rich surface phosphate groups, and carried a large number of negative charges. The adsorption capacity of PR-BMO for model RE³⁺ (La³⁺) was up to 537.92 mg·g^–1, which was significantly higher than that of BMO without phosphate functionalization and chemical manganese oxides. Adsorption kinetic, isotherm, thermodynamic studies, and spectroscopic techniques revealed the adsorption of RE³⁺ by PR-BMO was a complex but feasible endothermic process, coexisting electrostatic attraction, and coordinated complexation. Owing to the high affinity of phosphate groups to RE³⁺, PR-BMO showed outstanding selectivity for RE³⁺ adsorption despite the presence of typical coexisting ions (Na⁺, K⁺, Mg²⁺, Ca²⁺, Cl^–) and possessed great adsorption capacities toward various RE³⁺ including La³⁺, Ce³⁺, Nd³⁺, Pr³⁺, Y³⁺, and Dy³⁺. Notably, PR-BMO could reduce the concentration of RE³⁺ in low-concentration wastewater to nearly 0 mg·L^–1 and concentrate the RE³⁺ from 10 to 1811.5 mg·L^–1 through enrichment treatment. This study gives new insight into the treatment of rare earth industrial effluents and expands the application of BMO.","PeriodicalId":39,"journal":{"name":"Industrial & Engineering Chemistry Research","volume":"32 1","pages":""},"PeriodicalIF":4.2,"publicationDate":"2025-01-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143050231","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 study, a melamine-modified titanium dioxide (TiO₂) photocatalyst was synthesized via a straightforward hydrothermal and calcination method, using tetrabutyl titanate as the titanium precursor and melamine as the carbon source. This study explores the synthesis of melamine-modified anatase TiO₂ and its application in the photocatalytic degradation of tetracycline (TC) across various water sources. After 180 min of continuous light exposure, the melamine-modified TiO₂ (CT3) exhibited the optimum photocatalytic performance, achieving a degradation rate of 91.29% in seawater and approximately 90% in Xiangjiang River water and groundwater. Additionally, CT3 demonstrated a significant increase in hydrogen production, reaching 15,649 μmol/g, a substantial enhancement compared to unmodified TiO₂. The photocatalytic reaction mechanism was investigated through radical trapping experiments, and the analysis of TC degradation intermediates. Toxicity analysis of the intermediates emphasized their potential environmental impacts. Combined with characterization and experimental findings, the results demonstrate that melamine modification enhances electron capture and transport, facilitating charge transfer and separation of photogenerated carriers, thereby significantly boosting photocatalytic activity. This research highlights the potential of melamine-modified TiO₂ in effectively addressing environmental contamination and advancing sustainable energy solutions.","PeriodicalId":39,"journal":{"name":"Industrial & Engineering Chemistry Research","volume":"9 1","pages":""},"PeriodicalIF":4.2,"publicationDate":"2025-01-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143044217","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, controlling multiple critical quality attributes (CQAs) simultaneously is challenging due to trade-offs between various mechanisms influenced by limited operating conditions. To enhance the controllability, crystallization is often integrated with other unit operations, requiring an overall process designed as an integrated system. This paper focuses on a continuous 3-stage crystallization, wet milling, and classification system within a quality-by-digital design (QbDD) framework. Emphasizing process intensification and sustainability, the system incorporates recycling to increase robustness. The attainable region of the crystal size and impurity is broadened through recirculation and the integration of downstream units. The effects of design variables on start-up behavior are also analyzed, and kinetic parameter uncertainties are studied for robustness. Validation experiments confirm that the digital design successfully predicts the system behavior for CQAs of crystal size and impurity.","PeriodicalId":39,"journal":{"name":"Industrial & Engineering Chemistry Research","volume":"117 1","pages":""},"PeriodicalIF":4.2,"publicationDate":"2025-01-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143050278","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, carbon–carbon (C–C) coupling reactions are required to increase the molecular weight of hydrocarbon precursors, which can be further processed to yield jet fuel-range alkanes. In this work, two different hierarchical H–Y zeolites (H–Y-mod-1 and H–Y-mod-2) were synthesized using a surfactant-templating method to catalyze the hydroxyalkylation–alkylation (HAA) reactions of 2-methylfuran (2-MF) with furfural (FF) to produce a C₁₅ hydrocarbon precursor. Specifically, hierarchical H–Y-mod-1 zeolite achieved a ninefold increase in C₁₅ precursor yield (71.7 ± 0.2 mol %) compared to parental H–Y zeolite (4.3 ± 0.1 mol %) at 80 °C for 5 h of residence time. This enhanced catalytic activity of the hierarchical H–Y-mod-1 zeolite was attributed to its mesoporosity and strong Brønsted acidity in comparison to parental H–Y. Catalyst recyclability studies showed that hierarchical H–Y-mod-1 can be used up to three times, with a 28.7% decrease in C₁₅ yield only after the third recycling cycle. These findings suggest that fine-tuned acidic zeolites can be leveraged to catalyze HAA reactions to produce jet fuel precursors.","PeriodicalId":39,"journal":{"name":"Industrial & Engineering Chemistry Research","volume":"16 1","pages":""},"PeriodicalIF":4.2,"publicationDate":"2025-01-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143050277","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, recently developed techniques to learn interpretable dynamical models from data are susceptible to inherent experimental noise, especially in reaction kinetics data. Here, we address these issues by (1) employing a new derivative-free technique for sparse identification of dynamical equations that approximates the integral rather than the derivative (which we call as <i>DF-SINDy</i>) and (2) including domain information such as mass balance and chemistry information. We demonstrate this using retrospective examples to recover the true (known) governing equations from synthetic data under varying noise levels, sampling frequencies, and number of experiments. We observe that (1) models discovered from <i>DF-SINDy</i> have lower errors than those discovered from <i>SINDy</i> ( <cite><i>Proc. Natl.\u0000Acad. Sci.

Chemical recycling processes are powerful tools for managing the end-of-life of PA, obtaining constituent monomers, or other value-added chemical products. To achieve a high depolymerization efficiency as well as monomer selectivity, several chemical recycling processes have been demonstrated. Accordingly, this review summarizes recent advances in the chemical recycling and upcycling of PA (especially PA 6 and PA 66). We highlight three research topics: catalyst development, decomposing agent’s interaction, and process intensification. We expect to provide inspiration for PA depolymerization at different scales, which will contribute to the sustainability of PA throughout its entire lifecycle.","PeriodicalId":39,"journal":{"name":"Industrial & Engineering Chemistry Research","volume":"63 1","pages":""},"PeriodicalIF":4.2,"publicationDate":"2025-01-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143044210","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}

Experimental results indicate that continuous steaming of rice straw in saturated steam at temperatures between 150 and 210 °C leads to significant softening and pore-opening effects on the biomass cell structure. Consequently, subsequent atmospheric-pressure boiling-water extraction achieves high removal rates of potassium (56.9–77.4%), chlorine (82.2–97.0%), and sulfur (81.3–87.5%).
