Afterward, a two-level scheduling model was developed to optimize both economic efficiency and low-carbon performance. The first level applied a price-based demand response mechanism to adjust the electricity load and determine the optimal time-of-use price, while the second level employed a time-related scheduling mode for the system configuration. As a result, for a typical 600 MWe CFPP, the highest daily profit can reach $484367, exhibiting improvements of 12.59% and 14.69% over systems operating under fixed operation conditions and electricity prices, respectively.

However, the intrinsic role of pore size in modulating catalytic performance remains poorly understood. Herein, we report that the reactivity of ammonium nitrate (AN), a critical meltable intermediate in the reaction of NH3 selective catalytic reduction (NH3–SCR), can be effectively manipulated by simply adjusting the mesopore size of silica supports, while preserving identical active sites. For the investigated catalysts of Fe2O3 confined in mesoporous silica (Fe2O3@meso-SiO2), we demonstrate that catalytic activity exhibits a strong positive correlation with mesopore size for both SBA-15 and KIT-6 confined catalysts in the medium- to low-temperature range, independent of the mesoporous architecture. AN-temperature-programmed desorption (AN-TPD) revealed that the behavior of AN can be systematically tuned by mesopore size. Larger pores raise the equilibrium vapor pressure of molten AN via the Kelvin effect, enriching the local gaseous AN concentration. Following Le Chatelier’s principle, this elevated concentration shifts the surface adsorption equilibrium of AN on active sites and accelerates the reaction between AN and NO to yield N2. Our work underscores the importance of pore size engineering for tuning the local concentration of meltable reactive intermediates, offering a new avenue for the rational design of high-performance NH3–SCR catalysts.","PeriodicalId":39,"journal":{"name":"Industrial & Engineering Chemistry Research","volume":"20 1","pages":""},"PeriodicalIF":4.2,"publicationDate":"2026-10-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149151334","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 optimal electrode (E4, 6 wt %) exhibits a well-balanced charge storage mechanism with 81.7% capacitive and 18.3% diffusion-controlled sorption contributions, which facilitates fast mass transport accompanied by faradaic redox mechanisms of the systematic composite loading variation (0–8 wt %). The high specific capacitance (142 F g–1), low charge transfer resistance (1.3 Ω), and high Coulombic efficiency (99.99% for 500 cycles) via electrochemical measurements confirmed enhanced conductivity and reversibility. At optimum CDI operating conditions (1.2 V, 20 mL min–1, pH 4), the electrode exhibited an impressive electrosorption capacity (58.03 mg g–1, 95% removal). Kinetic studies showed a pseudo-first-order model (k1 = 0.0658 min–1, R2 = 0.9934) with high consistency between experimental (58.03 mg g–1) and theoretical capacities (64.01 mg g–1), and the linear driving force model gave a high mass transfer coefficient (kLDF = 0.0962 min–1), confirming efficient ion diffusion within the hierarchical structure. The improved performance is due to the combined contribution of pseudocapacitive property (GO), active Fe3+/Fe2+ sites of MIL-88A, and electric double-layer capacitance (AC) for the coupled electrosorption–desorption process. This work demonstrates the potential of a hybrid redox-capacitive system for energy-efficient Cu2+ recovery from industrial wastewater treatment.","PeriodicalId":39,"journal":{"name":"Industrial & Engineering Chemistry Research","volume":"45 1","pages":""},"PeriodicalIF":4.2,"publicationDate":"2026-10-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149151336","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 method also resolves three-dimensional, time-dependent velocity fields. The derived mean velocity profiles agree well with the theory of flow over porous walls. Beyond averaged Eulerian velocities, the Lagrangian framework captures near-surface interactions. The Lagrangian analysis of different surfaces indicates that rectangular structured microgrooves increase the wall contact of the tracer particles, especially when the flow is oriented perpendicular to the microgrooves. Particularly, this approach enables resolution of trapping phenomena and localized recirculation dynamics. Nanostructuring by growing a carbon nanotube forest increases surface area and modifies local fluid dynamics, thereby enhancing contact with (bio)catalysts that are potentially functionalized on the nanotubes in future applications.","PeriodicalId":39,"journal":{"name":"Industrial & Engineering Chemistry Research","volume":"44 1","pages":""},"PeriodicalIF":4.2,"publicationDate":"2026-10-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149151278","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 particular, the 5Cu+1Ru/5Ce-TiO2 catalyst exhibited the optimal surface acidity, achieving over 70% N2 selectivity at 300 °C, which was noticeably higher than the 45% N2 selectivity of 1Ru/5Ce-TiO2. A systematic study was conducted to compare the 1Ru/5Ce-TiO2 and xCu+1Ru/5Ce-TiO2 catalysts in terms of their textural and structural properties, surface chemical states, redox and acid properties, and catalytic performance. The results indicate that the introduction of CuSO4 improves the dispersion of active sites, promotes the formation of Cu–Ce interfaces, increases the number of surface acid sites, enhances the redox properties, and facilitates the generation of reactive oxygen species. More importantly, CuSO4 addition alters the NH3 oxidation pathway by promoting the formation of HNO and NHx intermediates, thereby directing the reaction toward the desired N2 product.

Building upon prior methodologies, this study proposes a systematic optimization approach for multiperiod heat exchanger network (MP-HEN) synthesis integrated with a postcombustion carbon capture (PCC) process to improve sustainability and reduce carbon emissions. The heat sink set is extended to include the stripper reboiler duty of the PCC column, which is regressed as a function of fired heater load derived from HEN fuel gas consumption. The regression is supported by a sequence of analyses based on rigorous N-methyldiethanolamine/piperazine (MDEA/PZ)-based PCC simulations. Carbon capture costs associated with variable reboiler duty are incorporated into the Total Annual Cost (TAC), enabling simultaneous economic and environmental optimization within a multiobjective optimization function. The PCC heat demand is supplied by recovered HEN waste heat and, when required, external hot utility input. Using a three-step decomposition algorithm, the method optimizes the HEN configuration, integrates PU heat transfer for carbon capture, and performs module simulations to validate overall system performance. An industrial-scale crude oil distillation preheat train case study demonstrates that the framework can effectively decarbonize the crude distillation system. Relative to the Base-WRDC benchmark, the integrated PCC-HEN solutions achieve a 38.1% CO2 reduction at 15 °C while maintaining a lower TAC. Relaxing the minimum approach temperature to 10 °C further increases the CO2 reduction to 65.0%.","PeriodicalId":39,"journal":{"name":"Industrial & Engineering Chemistry Research","volume":"36 1","pages":""},"PeriodicalIF":4.2,"publicationDate":"2026-10-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149151393","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}
