However, most biphasic absorbents still face challenges such as low cyclic capacity and high viscosity of the rich phase. To develop a novel solvent with enhanced cyclic capacity and reduced regeneration energy consumption, a biphasic solvent consisting of DETA/Isobutanol/H₂O was proposed. The results demonstrate excellent absorption and desorption performance of the DETA/Isobutanol/H₂O biphasic solvent, with an absorption capacity ranging from 1.13 to 1.35 mol/mol and a cyclic capacity ranging from 0.61 to 0.84 mol/mol. After conducting 5 times absorption-desorption experiments, the cyclic capacity of DETA/Isobutanol/H₂O biphasic solvent remained at 0.8 mol/mol. The estimated energy consumption for regeneration, under lean phase load, was calculated to be 2.42 GJ/t CO₂, which was 42.24 % lower than that of 30wt% MEA aqueous solution (4.19 GJ/t CO₂). The DETA/Isobutanol/H₂O solution exhibits promising potential in terms of absorption-desorption performance and regenerative energy consumption, making it an exceptional CO₂ absorbent.</p></div>","PeriodicalId":9387,"journal":{"name":"Carbon Capture Science & Technology","volume":"13 ","pages":"Article 100235"},"PeriodicalIF":0.0,"publicationDate":"2024-07-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2772656824000472/pdfft?md5=02b9db401dc3e7f849b93be665bee3a4&pid=1-s2.0-S2772656824000472-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141540640","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Lignin-derived porous carbons have gained increasing attention for CO₂ adsorption application due to their abundant and cost-effective raw material sources. This study involves the synthesis of a series of porous carbons derived from sodium lignosulphonate using chemical activation and template methods. It was found that synthesis methods had significant influence on the properties of the obtained porous carbons, including texture structures and surface functional groups. The pore structure of the carbons obtained through the activation methods primarily consisted of etched channels, while that of the carbons acquired via the template methods predominantly originated from stacked sheet carbon. In comparison to the carbon samples obtained from template methods, chemically-activated porous carbons exhibited higher specific surface areas (1125 m²/g for the ZnCl₂-activated sample and 1998.4 m²/g for the KOH-activated sample) and more micropores. The variations in the characteristics of the carbon samples derived from lignin with different synthesis methods also affected their CO₂ adsorption performance. The CO₂ adsorption capability of the chemically-activated porous carbons indicated their superior suitability for CO₂ adsorption due to their higher specific surface area and abundant sulfur- and oxygen-containing functional groups. Notably, the porous carbons prepared with ZnCl₂ as the activation agent (C-LS-ZnCl₂) exhibited the most remarkable adsorption capacity of 4.45 mmol/g at 273 K and 100 kPa, and high CO₂/N₂ selectivity. The adsorption-desorption cycles confirmed the remarkable stability and regeneration ability of C-LS-ZnCl₂. This study findings suggest that the utilization of the ZnCl₂ activation method exhibits significant potential in transforming industrial lignin waste (sodium lignosulphonate) into a suitable adsorbent for CO₂ adsorption.</p></div>","PeriodicalId":9387,"journal":{"name":"Carbon Capture Science & Technology","volume":"13 ","pages":"Article 100233"},"PeriodicalIF":0.0,"publicationDate":"2024-06-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2772656824000459/pdfft?md5=ee338a949ff4ef03f67a1d6c7a83b577&pid=1-s2.0-S2772656824000459-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141486581","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Varying Ru concentrations were introduced, including 0.2, 0.5, 1.0, 2.0, and 5.0 wt%, resulting in different Ru particle sizes on g-C₃N₄ support. Through a multifaceted characterization approach, it was observed that the catalyst containing 1 wt% Ru loading displayed superior performance, with a high density of active sites, indicated by an enhanced CO₂ conversion rate of 36.8 % at 450 °C and a CO yield of 25 %. This catalyst also exhibited remarkable CO selectivity of 83 % at 375 °C. Conversely, lower loadings of 0.2 and 0.5 wt % Ru were found to be less effective, yielding minimal CO₂ conversion. Loadings above 1 wt% Ru, while achieving high CO₂ conversion, demonstrated a preference for CH₄ production over CO, indicating lower selectivity for the desired product. This study elucidates the critical role of Ru nanocluster size in the catalytic activity and selectivity, with 1 wt % Ru-supported g-C₃N₄ emerging as a promising candidate for selective CO generation from CO₂ hydrogenation, offering a pathway for the valorization of CO₂ as a raw material in the chemical industry.</p></div>","PeriodicalId":9387,"journal":{"name":"Carbon Capture Science & Technology","volume":"13 ","pages":"Article 100248"},"PeriodicalIF":0.0,"publicationDate":"2024-06-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2772656824000605/pdfft?md5=bba456e443c3eb656e41644a6c53e4c3&pid=1-s2.0-S2772656824000605-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141486582","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Herein, a series of commercial resin particles (1.0 mm) were used as supports, and it was found that X5 exhibited favorable support characteristics in the preparation of solid amine adsorbents.
