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 DF-SINDy) 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 DF-SINDy have lower errors than those discovered from SINDy ( <cite>Proc. Natl.\u0000Acad. Sci. U.S.A.</cite> 2016, 113, 3932−3937, DOI: 10.1073/pnas.1517384113) and (2) adding domain knowledge further helps recover correct terms, thereby improving the reliability of the interpretations obtained from these models.

Experimentally, microporous carbons were synthesized from asphalt using K2CO3 as an activator, with pore structures tailored by varying activation conditions. The optimized sample achieved a maximum adsorption capacity of 210 mg/g (C0 = 400 ppm, T = 25 °C), demonstrating a strong correlation (R2 = 0.997) between pore volume (<1.0 nm) and adsorption capacity, consistent with simulation predictions. Isotherm and thermodynamic analyses indicated that the adsorption process adhered to the Langmuir and Dubinin–Radushkevich models (R2 > 0.99) and was spontaneous and exothermic. Reusability tests showed 91% of the adsorption capacity retention after five cycles, highlighting the material’s practical potential.

However, the high consumption of the commodity PA has posed a considerable and urgent waste management challenge. As the concept of a circular economy is deeply rooted, there have been numerous circular solutions for PA waste recycling. 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}

The reaction process of ethanol dehydration on mesoporous-silica-SBA-15 (SBA-15)-supported heteropolyacids (HPAs) involves complex parallel-consecutive pathways, which differ from those involved in pure HPAs systems. Notably, the reaction progresses from the formation of diethyl ether at lower temperatures to the complete generation of ethylene at higher temperatures. To conserve energy, achieving high selectivity for ethylene at lower temperatures is crucial. In this study, we impregnated 12-tungstophosphoric acid into an SBA-15 catalyst, followed by microwave-assisted heating to obtain a catalyst that facilitates the dehydration of ethanol to ethylene. Experimental findings revealed that this catalytic technique achieves a reaction at lower temperatures than conventional thermal catalysis, exhibiting conversion rates and selectivity values exceeding 99%. Additionally, the influence of the substrate on the entire reaction process was elucidated by clarifying the reaction pathways using theoretical calculations.","PeriodicalId":39,"journal":{"name":"Industrial & Engineering Chemistry Research","volume":"60 1","pages":""},"PeriodicalIF":4.2,"publicationDate":"2025-01-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143044223","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 research, renewable biobased CNCs were modified using silylation, which is based on introducing a siloxane group to increase the compatibility between CNCs and the polydimethylsiloxane (PDMS) polymer. A silylated CNC/PDMS composite membrane was manufactured, which has applications in air dehydration. For this purpose, spray-dried CNC powder was used and modified. The surface modification of CNCs was carried out through the reaction between hydroxyl groups of the CNCs and the silylation agent. Finally, the silylated CNCs (SCNCs) were added to the PDMS solution to make SCNC/PDMS membrane samples with an SCNC weight concentration of 2%. Characterization analyses of FTIR and XRD of SCNCs confirmed the effectiveness of the silylation. SEM, AFM, and polarized light microscopy analyses indicated the improved dispersion of SCNCs in the polymer matrix compared to the not-modified CNC. The SCNC/PDMS membrane exhibited a 23% increase in water vapor permeability and a 79.6% increase in selectivity for water vapor over nitrogen gas at 25 °C compared to the pure PDMS membrane. Furthermore, the thermo-mechanical analysis (TMA) technique provided evidence that the addition of both CNC and SCNC resulted in a decrease in the coefficient of thermal expansion (CTE) of the PDMS membrane. These findings contribute to the development of cellulose-based materials with improved performance for their potential applications in various fields.","PeriodicalId":39,"journal":{"name":"Industrial & Engineering Chemistry Research","volume":"34 1","pages":""},"PeriodicalIF":4.2,"publicationDate":"2025-01-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143044819","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}
