In this study, nitrogen-rich microporous carbon materials (NCTs) were successfully synthesized via a one-step molten salt polycondensation and carbonization method which was used as an adsorbent for CO₂ capture. Triglycidylisocyanurate and dicyandiamide were used as precursors, while potassium citrate served as both a template and an activator. By adjustment of the molten salt ratio and carbonization temperature, the pore structure and nitrogen doping level were effectively optimized. The resulting NCT-650-<i>M</i> exhibited excellent structural properties, including a high nitrogen content (13.46 wt %), a substantial pore volume (0.65 cm³ g^–1), and a large specific surface area (1257.1 m² g^–1). Subsequently, the CO₂ adsorption performance was evaluated using three different methods: thermogravimetric static adsorption, CO₂ fixed-bed adsorption, and CO₂ adsorption isotherms, which revealed a CO₂ uptake capacity of 4.19 mmol g^–1 at 25 °C and 1 bar. Moreover, exceptional adsorption selectivity and robust cyclic stability in CO₂/N₂, CO₂/CH₄, and CO₂/O₂ separation systems were accomplished, complemented by a detailed investigation into the influence of water vapor under controlled humidity conditions on the CO₂ adsorption performance. The mechanisms of CO₂ adsorption were thoroughly investigated, revealing the key factors that contribute to its exceptional performance.

In this paper, Cobalt-based metal–organic frameworks (Co-MOF) were prepared from PET by one-pot solvothermal method without adding acids or bases. The prepared Co-MOF was used as a heterogeneous catalyst to catalyze the selective oxidation of ethylbenzene (EB) for the preparation of acetophenone (AP). When only <i>tert</i>-butyl hydroperoxide (TBHP) was used as the oxidizing agent without any additional solvents, 89% EB conversion and 94% AP selectivity were achieved, respectively. Moreover, the catalyst showed excellent stability with no significant deactivation under 5 cycles. In addition, the synthesized Co-MOF-10 also exhibits impressive conversion rates of 96% and 93% in benzyl alcohol and styrene oxidation, respectively. Compared with the Co-MOF prepared by commercial terephthalic acid (BDC), the Co-MOF-10 synthesized via the one-pot method using PET exhibits enhanced cost-effectiveness, environmental sustainability, and superior catalytic performance.

This study introduces a novel approach to enhancing epoxy coatings using chitosan-based polycarbamate derivatives synthesized via a nonisocyanate route, offering a safer and more sustainable pathway for generating isocyanates. The successful formation of isocyanate from chitosan-based polycarbamate was confirmed by using experimental techniques such as CO₂ evolution, TGA, and DSC, along with theoretical validation via Dmol3 transition state analysis. The generated isocyanate improved the mechanical, chemical, and thermal properties of epoxy coatings made from diglycidyl ether bisphenol A (DGEBA) and triethylenetetramine (TETA). Cure time analysis showed that incorporating chitosan-blocked isocyanate significantly increased cross-linking density, resulting in more than twice the tensile strength of modified epoxy films (51 MPa) compared to unmodified ones (24 MPa). Additionally, the modified coatings exhibited better flexibility, stiffness, chemical resistance, UV stability, and lower surface wettability. The chitosan-based polycarbamate system presents a scalable, cost-effective solution for industries seeking greener alternatives in protective coatings, adhesives, and advanced polymer applications. These findings pave the way for the industrial adoption of biobased, high-performance materials, promoting environmental sustainability without compromising functionality.","PeriodicalId":39,"journal":{"name":"Industrial & Engineering Chemistry Research","volume":"183 1","pages":""},"PeriodicalIF":4.2,"publicationDate":"2025-03-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143695610","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}

{"title":"A Performance Modeling Study for Zero Fossil CO2 Stack Operation and Solvent Thermal Reclaiming in Post-Combustion Capture Industrial Applications","authors":"Stavros Michailos, Mathieu Lucquiaud, August D Benz, Daniel Mullen, William Elliott, Jon Gibbins","doi":"10.1021/acs.iecr.4c04530","DOIUrl":"https://doi.org/10.1021/acs.iecr.4c04530","url":null,"abstract":"Post-combustion capture (PCC) of CO&lt;sub&gt;2&lt;/sub&gt; is widely recognized as the most mature technology to mitigate CO&lt;sub&gt;2&lt;/sub&gt; emissions from existing fossil fuel-based power plants and industrial sources, and successful deployment will predominantly rely on the ability of the PCC plant to consistently achieve high capture fractions. To this end, the performance modeling study presented herein is the first attempt to identify engineering options for long-term, cost-effective windows for zero fossil CO&lt;sub&gt;2&lt;/sub&gt; stack emission PCC operation, when 100% of the added fuel CO&lt;sub&gt;2&lt;/sub&gt; (100% of the fossil CO&lt;sub&gt;2&lt;/sub&gt;) is captured, in key industrial applications including combined cycle gas turbine (CCGT) power plants, steel, cement, energy from waste (EfW), and oil refining (fluidized catalytic crackers). Furthermore, low-cost designs for effective solvent recovery through thermal reclaiming with effective energy recovery are analyzed for the first time for nonproprietary, open-art aqueous MEA solvent at 35% w/w (unloaded). At 100% capture of the added fuel CO&lt;sub&gt;2&lt;/sub&gt;, low lean loadings (between 0.1 and 0.12 molCO&lt;sub&gt;2&lt;/sub&gt;/molMEA) enhance mass transfer in the absorber, while a raised desorber pressure of 2.4 bar limits excessive energy consumption. In fact, for an absorber packing height of 20 m (2 × 10 m beds), the optimum specific reboiler duty (SRD) to capture 100% of the added fuel CO&lt;sub&gt;2&lt;/sub&gt; (zero fossil CO&lt;sub&gt;2&lt;/sub&gt; stack operation) was found to lie between 3.62 and 3.96 GJ/tCO&lt;sub&gt;2&lt;/sub&gt;, while for a 3 × 8 m bed absorber, i.e., 24 m, the SRD drops to 3.46–3.75 GJ/tCO&lt;sub&gt;2&lt;/sub&gt;, both cases well within the range of reported energy penalty for 90–95% capture, which has significantly higher residual CO&lt;sub&gt;2&lt;/sub&gt; emissions. Furthermore, we analyzed two strategies of continuously operating a thermal reclaimer, i.e., single-stage and two-stage reclaiming systems (the first operates at stripper pressure while the second one at atmospheric) with effective energy integration and consideration of both volatile and nonvolatile components. Two-stage reclaiming can substantially reduce water addition compared to single-stage reclaiming from 100 to 400% of the reclaimer solvent flow to 0–50%. Yet, there exists a trade-off, namely, the greater the MEA recovery, the greater the uptake of volatile thermal degradation products. For example, in the case of single-stage reclaiming operation, for ∼90% MEA recovery, approximately 35% of the HEEDA is recycled to the PCC, and when MEA recovery increases to ∼95%, the associated HEEDA return reaches ∼52%. Effective integration of thermal reclaiming with the desorber results in a small additional electricity output penalty, i.e., ranging from 0.3 to 1.13% relative to the output with capture but with no reclaiming. However, it should be noted that a solvent management technique is essential to an amine-based PCC as accumulation of degradation products will affect capture efficiency and associated en","PeriodicalId":39,"journal":{"name":"Industrial & Engineering Chemistry Research","volume":"56 1","pages":""},"PeriodicalIF":4.2,"publicationDate":"2025-03-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143678138","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}

On this basis, BO solubility was measured and finally compared with the UNIFAC model, and it was found that the kinetics of epoxidized butane was modeled in the same way as the ethoxylation and propoxylation of primary fatty alcohols.

Optimizing the porosity, morphology, and interconnectivity of the pores in CAPs is essential for effective photocatalysis. In this study, a molybdenum disulfide/graphene CAP was synthesized and modified through physical activation to improve its photocatalytic activity for tetracycline (TC) degradation under visible-light irradiation. Activation with carbon dioxide (CO₂) significantly enhanced photocatalytic performance by increasing specific surface area, pore volume, and mesopore size, thereby improving light absorption and charge separation. This enhancement resulted from the Boudouard reaction, which created pores or defects in the graphene lattice. However, excessive pore formation could compromise the structural integrity of the graphene sheets. The CAP activated at 750 °C degraded 95% of TC in 90 min under visible light, outperforming both unactivated and chemically activated CAPs. These results demonstrate that CO₂-mediated physical activation is a promising approach to improving CAP performance for wastewater treatment.","PeriodicalId":39,"journal":{"name":"Industrial & Engineering Chemistry Research","volume":"41 1","pages":""},"PeriodicalIF":4.2,"publicationDate":"2025-03-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143672755","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}
