Due to the combined influence of multiple factors such as process parameters, equipment status, and environmental disturbances, electricity consumption data exhibits complex characteristics. These include high time-delay, pronounced nonlinearity, and multivariate coupling, which pose significant challenges for long-term trend modeling and prediction. This paper addresses the challenge of long sequence time-series forecasting (LSTF) for electricity consumption in the cement calcination process by proposing a predictive model, MSTFormer. It integrates multi-channel time-series inputs with a spatio-temporal self-attention mechanism. The model first preprocesses the raw electricity consumption signals using variational modal decomposition. It then constructs a parallel multi-channel time-series input structure based on a weighted mechanism, effectively enhancing long-term dependency modeling capabilities. Subsequently, a novel spatiotemporal ProbSparse self-attention mechanism is designed, combining spatio-temporal embedding and causal convolution to adaptively extract global trends and local dynamic features, thereby enhancing the model’s ability to capture complex time-series patterns. Experimental results on actual cement production datasets demonstrate that MSTFormer outperforms mainstream long-sequence forecasting models across various prediction lengths. Compared with other decomposition methods, VMD-based decomposition reduces prediction errors by over 30%. For 15-minute prediction length, the model achieves an MAE of 0.063 and R² of 0.991. Even at 60-minute length, it improves prediction accuracy by over 24%. This study provides an effective approach for intelligent scheduling and energy optimization, offering theoretical and practical value for enhancing industrial energy efficiency.","PeriodicalId":271,"journal":{"name":"Chemical Engineering Science","volume":"93 1","pages":""},"PeriodicalIF":4.7,"publicationDate":"2025-09-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145140570","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"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 novel magnetic hollow porous copper-based Fenton-like catalyst using cattail sporopollenin as a skeleton support (CSp/Fe₃O₄-Cu₂O) was developed for the first time for the adsorption and efficient degradation of two refractory organic dyes rhodamine B and methylene blue in aqueous environments. Under the optimal conditions, CSp/Fe₃O₄-Cu₂O showed complete ability to degrade the mixed dyes. The degradation kinetic constant of CSp/Fe₃O₄-Cu₂O increased by 10.57 times compared to the control Fe₃O₄-Cu₂O. The hollow porous structure of cattail sporopollenin (CSp) in CSp/Fe₃O₄-Cu₂O not only adsorbed the dyes, but also promoted the continuous generation of active species by facilitating the redox cycling of Cu²⁺/Cu⁺ through the adsorption of Cu²⁺, which synergistically realized the efficient degradation of mixed dyes. Furthermore, CSp/Fe₃O₄-Cu₂O showed promising application potentials as follows: degradation rates of over 96 % for mixed dyes in a wide pH range of 3.0–11.0; complete degradation of mixed dyes in various water matrices including ultrapure water, tap water, and Songhua River water; and degradation rates of over 98 % for mixed dyes after six consecutive cycles. Overall, the novel Fenton-like catalyst CSp/Fe₃O₄-Cu₂O developed in this study was found to be highly promising for the treatment of organic dye-contaminated water in chemical industries.

Among various catalytic systems, Pt-based bimetallic catalysts have attracted significant research attention due to their superior catalytic performance and potential for cost reduction. In this study, we conducted a systematic investigation into the influence of the introduction of Fe-series atoms (Fe, Co, Ni) on 12H-NECZ dehydrogenation reactions of Pt/TiO₂ catalyst. The results demonstrate that the introduced Fe-series atoms facilitate enhanced orbital hybridization, particularly between their 3d orbitals and the Pt-5d orbitals, leading to a pronounced spin polarization effect, modulating the d-band splitting (Δε_d). These atoms have excellent electron migration properties, which increase the electron density around the Pt atoms. This electronic restructuring modulates the dual d-band centers of the metal Pt, weakens the strong adsorption of reaction intermediates/products and dramatically reduces the energy barrier of the breaking of C–H bonds. Specifically, the rate-determining-step (RDS) barrier of the most effective Pt₃Co/TiO₂ catalyst is 0.43 eV lower than that of Pt/TiO₂, which is attributed to the moderate spin polarization strength and optimal electron structure, balancing the adsorption of intermediates/products (ε_d↑) and hydrogen (ε_d↓).

CT 3D reconstruction and positive-deviation correction of the SAXS data were performed to systematically quantify the geometry, structural parameters, and spatial arrangement of the pore-fracture.

Based on the computational results obtained by performing the density functional theory (DFT) calculations, the sequence of bonds formation and interaction in these precursor molecules during their reaction with water align with the adsorption mechanism on the Si(100) surface. The differences in the relative energy at each stage of the reaction allow their comparison in terms of the reaction rate and process temperature.

This observation aligns with the adsorption behavior of TTIP and Ti(OCH₃)₄ molecules on hydroxylated Si(100) surfaces, which exhibit activation barriers of 13.4 and 11.5 kcal/mol, respectively. These findings support the hypothesis that precursor molecules with lower decomposition barriers tend to adsorb more readily onto substrate surfaces and generally require lower process temperatures.

In the traditional data-driven reconstruction framework, the underdetermined mapping from low-dimensional bulk properties to high-dimensional molecular compositions and the limited interpretability remain prominent challenges. In this study, a novel strategy is proposed for molecular composition reconstruction of naphtha fractions by integrating data-driven modeling with interpretable optimization. A feedforward neural network (FNN) is pre-trained to map molecular composition to bulk properties. For each sample to be reconstructed, the parameterized FNN is then embedded into an inverse optimization problem to reconstruct the molecular composition. Furthermore, a sample-specific reference composition is constructed from the database to guide the reconstruction, along with carbon number distribution and structural distribution profiles, ensuring chemical plausibility and similarity to realistic petroleum compositions. The reconstructed compositions demonstrate high accuracy. Model interpretability analysis using SHapley Additive exPlanations (SHAP) demonstrates that selecting key bulk properties facilitates the establishment of a robust and unbiased mapping between composition and properties. Furthermore, a broader set of bulk properties are predicted by a supplementary extreme gradient boosting model using limited key properties and its reconstructed composition as inputs.","PeriodicalId":271,"journal":{"name":"Chemical Engineering Science","volume":"15 1","pages":""},"PeriodicalIF":4.7,"publicationDate":"2025-09-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145141027","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
