However, existing research results have shown that conventional single-stage PSA typically cannot achieve 95% purity CO₂ with 90% recovery using most commercial adsorbents. Dual reflux pressure swing adsorption (DR-PSA) is a special process that combines stripping and enriching PSA, where light and heavy products with high purity and high recovery can be obtained simultaneously. However, its industrial applications are limited by the problems of discontinuous feeding and high energy consumption. To overcome these limitations, a 4-bed continuous DR-PSA was developed and simulated using a model validated against published experimental data, with simulated flue gas (CO₂/N₂ = 15%/85%) as the feed and silica gel as the adsorbent. After comparing internal state variables, four key parameters, including feed flow rate, step duration, light reflux-to-feed ratio, and feed position, were studied in detail. The results indicate that the proposed process can achieve CO₂ purity of 96.42% with 96.52% recovery, N₂ purity of 99.40% with 99.40% recovery, a productivity of 0.4607 mol CO₂/kg/h, and a specific energy consumption of 1.172 GJ/t CO₂. The process demonstrates significantly superior specific energy consumption compared to prior studies.</p></div>","PeriodicalId":458,"journal":{"name":"Adsorption","volume":"32 1","pages":""},"PeriodicalIF":3.1,"publicationDate":"2025-11-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145612874","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Therefore, in this study, hydrogen storage was examined theoretically into the MCM-41 mesoporous silica model. Plane-wave DFT calculations revealed the adsorption of hydrogen molecules into the MCM-41 model when nickel and palladium metals were present. Additionally, in the Metropolis Monte Carlo simulations, it was observed that the hydrogen molecule adsorption capacity increased with the amount of metal. For example, the amount of adsorbed hydrogen molecules at a pressure of 10 bar and 298 K temperature in systems containing 2.3% by weight of nickel and palladium was found to be 0.28% and 0.15%, respectively. When the metal content was approximately doubled, these values increased to 0.53% and 0.34% under the same pressure and temperature. When the temperature is decreased to 77 K, the amount of adsorbed H₂ increases to 1.2 wt% H₂ for the model with 23% Ni and 1.0 wt% H₂ for the model with the same percentage of Pd at 10 bar pressure. On the other hand, due to the H-bonds, hydrogen molecules interacted with the oxygen atoms belonging to pure MCM-41. Based on these results, it is evident from all theoretical studies that loading an equivalent weight ratio of Ni exhibited a higher hydrogen storage capacity compared to Pd. Moreover, it can be said that the MCM-41 model constructed in this theoretical study aligns well with literature as an ideal material for hydrogen storage.</p></div>","PeriodicalId":458,"journal":{"name":"Adsorption","volume":"31 8","pages":""},"PeriodicalIF":3.1,"publicationDate":"2025-11-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145456669","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The model is trained on an expanded dataset exceeding 2700 data points, encompassing diverse families, such as metal-organic frameworks (MOFs), zeolites, porous organic polymers (POP), and carbon-based materials (CBM). The CFNN is further optimized through three distinct learning algorithms, namely Levenberg–Marquardt, Bayesian Regularization, and Scaled Conjugate Gradient. Quantitatively, the CFNN-LM model achieved a determination coefficient (R²) of 0.9991 and a root mean square error (RMSE) of 0.0659, outperforming alternative ML frameworks and surpassing the models previously reported in the literature. Moreover, by integrating SHAP and LIME for global and local interpretability, we provide physical insights into the factors influencing adsorption performance under varying conditions.

It is difficult to distinguish the dynamics of individual processes from experiments that only allow access to the combined overall dynamics of all processes taking place. This works shows for the case of dimethyl sulfoxide (DMSO) vapor interacting with paper as a porous matrix that it is possible to distinguish experimentally the dynamics of the sorption and release processes of two populations of differently sorbed DMSO molecules, even though the temporal evolution of the sorbed concentration shows no evidence of multiple processes. The key to separating the processes lies in the release behavior. DMSO release from paper saturated with DMSO is a superposition of short- and long-term processes, with release rates of 3<span>(times)</span>10<span>(^{-4})</span>s<span>(^{-1})</span> and 1.1<span>(times)</span>10<span>(^{-6})</span>s<span>(^{-1})</span>, respectively. Such different rates indicate the presence of two types of sorbed populations with distinct release dynamics. This inspires a strategy to separate the sorption dynamics of the two populations as well. A sorption experiment was designed to determine the concentration of DMSO sorbed in the paper at a certain exposure time, and again after the short-term release was complete. This procedure yields the concentration of each sorbing species as a function of time. Successfully separating the process dynamics is important for clarifying the nature of the processes, such as determining activation energies, and for correctly describing the temporal evolution of sorption and release mathematically. This strategy may help reveal the dynamics of simultaneous, mutually obscuring processes in other systems as well.</p><h3>Graphical Abstract</h3><div><figure><div><div><picture><source><img></source></picture></div></div></figure></div></div>","PeriodicalId":458,"journal":{"name":"Adsorption","volume":"31 8","pages":""},"PeriodicalIF":3.1,"publicationDate":"2025-11-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s10450-025-00656-x.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145456390","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
