Within this coupled crystal, CALF-20, known for its strong adsorption capacity and excellent stability toward CO2 and H2S, serves as the outer layer crystal to shift the adsorption/desorption hysteresis loop of inner ZIF-7 to beyond atmosphere pressure. Under high pressure, CO2 and H2S are automatically adsorbed. Upon reducing the pressure to the atmospheric level, CO2 is automatically released, while H2S remains temporarily due to its high adsorption energy. After about 150 cycles of CO2 adsorption/desorption of the kilogram-scale composite, H2S approaches saturation and is then removed by vacuuming. Since the content of H2S in IGCC feed gas is trivial, the total energy consumption for the composite regeneration is 0.16 MJ/kg (CO2). After 600 consecutive cycles, the CO2 adsorption capability of the composite decreases by 0.41%, demonstrating excellent cyclic stability.","PeriodicalId":39,"journal":{"name":"Industrial & Engineering Chemistry Research","volume":"8 1","pages":""},"PeriodicalIF":4.2,"publicationDate":"2025-05-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144104016","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}

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}

To address this issue, a membrane-less self-stratified thermally regenerative flow battery was constructed to alleviate ammonia crossover. The interface visualization, power generation feasibility, and the effects of flow rate were investigated. The results reveal that the density difference of the anolyte/catholyte leads to self-stratification. The interface moves continually due to ammonia diffusion in the static catholyte, resulting in a significant decrease in the battery performance. By regulating the catholyte flow rate, a steady anode–cathode interface can be achieved, thereby solving the key problem of ammonia crossover and achieving stable power generation. Increasing the catholyte flow rate can produce a stable interface and prevent the interface from moving to the cathode. However, a high catholyte flow rate will allow the interface to surpass the anode electrode, causing battery performance to increase and then decrease with flow rate. Increasing the ammonia flow rate can effectively improve the anode mass transfer and battery performance. The interface is affected by temperature change, so the interface is investigated at different temperatures. Within a specific range, there is no significant change in the position of the interface, and the battery’s maximum power density improves linearly with temperature.","PeriodicalId":39,"journal":{"name":"Industrial & Engineering Chemistry Research","volume":"209 1","pages":""},"PeriodicalIF":4.2,"publicationDate":"2025-05-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144088116","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}

Pt-based nanofluid catalysts are effective in enhancing the chemical heat sink of endothermic hydrocarbon fuels (EHFs) by facilitating a catalytic dehydrogenation-cracking reaction. However, highly-dispersed Pt nanoparticles often face the problem of poor thermal stability in nanofluids. In this work, a NaH-assisted deprotonation method was applied to synthesize N-heterocyclic carbene (NHC)-capped highly-dispersed Pt nanoparticles (Pt@NHC14). The average size of the Pt nanoparticles in optimized Pt@NHC14 was 2.4 nm. Pt@NHC14 exhibited a high heat sink of 3.80 MJ/kg at 725 °C in the quasi-homogeneous conversion of decalin, which was 10% higher than Pt@ILs14 without a deprotonation strategy. This could be ascribed to the dehydrogenation process being promoted, which was verified by a hydrogen yield of 9.5% on highly dispersed Pt of Pt@NHC14, and that is 46% higher than that of Pt@ILs14. This research synthesizes N-heterocyclic carbene-capped highly-dispersed Pt nanoparticles and provides valuable insights into the strong endothermic technology.","PeriodicalId":39,"journal":{"name":"Industrial & Engineering Chemistry Research","volume":"9 1","pages":""},"PeriodicalIF":4.2,"publicationDate":"2025-05-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144088114","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}
