However, the low initial Coulombic efficiency (ICE) and suboptimal electrochemical windows (EWs) have posed significantly challenges to their commercialization. In this study, biomass-derived hard carbons were synthesized via the pyrolysis of polyethylenimine (PEI)-interpenetrated lignin precursors, aiming to enhance sodium-ion storage performance. High-resolution transmission electron microscopy (HRTEM) and small-angle X-ray scattering (SAXS) confirmed the formation of close-pores stacked by 3–5 layers pseudographitic crystallites, attributed to the interpenetration of long-chain PEI polymers. Cyclic voltammetry (CV) analysis revealed that the <i>b</i>-values of lignin/PEI (LP) hard carbons approached 0.5, indicative of a diffusion-controlled mechanism governing Na<sup>+</sup> storage. Electrochemical impedance spectroscopy (EIS) analyses further demonstrated notable reductions in both solid-electrolyte interface resistance (<i>R</i><sub>SEI</sub>) and charge transfer resistance (<i>R</i><sub>ct</sub>). Moreover, comprehensive electrochemical evaluations indicated that Lignin/PEI10000 (LP10000) hard carbon achieved an impressive reversible capacity of 277.2 mAh·g<sup>–1</sup>, with a plateau capacity of 188.3 mAh·g<sup>–1</sup> and a remarkable capacity retention rate at a current density of 30 mA·g<sup>–1</sup>.

A hierarchical approach efficiently streamlines the design space exploration, while technology readiness levels (TRLs) help determine the novelty of selected reactions. A methanol production case study from natural gas demonstrates the framework’s ability to uncover novel net-zero pathways. Notably, formaldehyde emerges as a key intermediate, and a direct synthesis route from recycled CH<sub>4</sub> (via CO<sub>2</sub>) significantly enhances overall performance.

Despite their advantages, the intricate hydrodynamics associated with the number of parallel plates remains inadequately understood. This study employs a two-fluid Eulerian model, integrated with the kinetic theory of granular flow, to investigate the influence of parallel plates on the hydrodynamics of inclination-augmented LSFBs. Key parameters, such as pressure drop, bed expansion, solid velocity, and solid volume fraction distribution, are systematically analyzed for varying numbers of plates. The results show that the pressure drop remains constant at low liquid velocities but increases significantly at higher velocities with the addition of more plates. This is due to a 20% higher accumulation of particles along the narrow inclined channels, which increases the flow resistance. Additionally, bed expansion decreases by approximately 15% as more inclined plates are added, limiting particle movement. However, increasing the number of plates beyond two (within a fixed bed width of 50 mm) has little effect on the flow behavior, suggesting an optimal limit for plate insertion in this setup.","PeriodicalId":39,"journal":{"name":"Industrial & Engineering Chemistry Research","volume":"17 1","pages":""},"PeriodicalIF":4.2,"publicationDate":"2025-05-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144088115","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}
