X-ray computed tomography (XCT) enables nondestructive 3D core imaging, but imaging noise degrades reconstruction accuracy and pore network authenticity. Existing research lacks in-depth analysis of denoising methods’ correlation with pore parameters. This study evaluates XCT datasets of carbonate cores, using entropy, structural similarity index (SSIM), porosity, and fractal dimension to compare traditional denoising methods via 3D pore network modeling. Findings show denoising methods significantly affect porosity calculations: total and connected porosity peak relative differences reach 30.5% and 40.95%, respectively. Tortuosity and pore coordination number are notably impacted, whereas fractal dimension and equivalent pore radius are less affected. Dual-filter combinations outperform single filters, whereas combinations of three or more filters are not recommended due to excessive smoothing. Although denoising alters parameter values, it preserves the spatial variation trend of core properties, guiding researchers to balance accuracy and efficiency when selecting denoising strategies. This study provides theoretical guidance for scientific denoising algorithm selection in digital core construction, enhancing microscopic reservoir characterization credibility and promoting precise digital core applications in petroleum engineering.</p>\u0000 </div>","PeriodicalId":12796,"journal":{"name":"Greenhouse Gases: Science and Technology","volume":"16 4","pages":"549-562"},"PeriodicalIF":3.2,"publicationDate":"2026-08-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148696591","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study introduces a hybrid carbon capture and storage (CCS) prototype that integrates mist-assisted absorption with coconut fiber adsorption as a low-cost and renewable approach. The system was evaluated in terms of CO₂ capture efficiency and energy consumption. The prototype consists of four chambers: mist generation units to enhance gas–liquid contact and coconut fiber packing to adsorb residual CO₂. Six experimental modes were tested at two gas flow velocities (0.9 and 1.4 m/s). Real-time CO₂ monitoring was performed using NDIR MH-Z16 sensors validated against a reference probe meter, with data acquisition through the NI MyRIO platform. Results showed that capture efficiency increased from 14% to 19% in the baseline condition to a maximum of 65.9% in the hybrid configuration combining six mist modules and coconut fiber. Energy consumption analysis revealed that the energy consumption index (ECI) ranged from 72.95 to 79.85 kWh/kg CO₂, with the lowest ECI obtained in the hybrid setup, although mist generation contributed significantly to power demand. Despite higher energy use compared with advanced chemical or vacuum swing adsorption systems, the prototype offers advantages in terms of simplicity, operational practicality, and use of renewable local resources. These findings demonstrate the potential of coconut fiber–based hybrid CCS systems as complementary solutions for decentralized and small-scale applications.</p>\u0000 </div>","PeriodicalId":12796,"journal":{"name":"Greenhouse Gases: Science and Technology","volume":"16 4","pages":"611-620"},"PeriodicalIF":3.2,"publicationDate":"2026-08-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148696487","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Although drivers of individual emissions are understood, the synergistic influence of socioeconomic factors on simultaneous reductions of multiple emissions is less explored, particularly from a systemic, consumption-based perspective. This study leverages China's multiregional input–output tables, combined with the structural decomposition analysis method, to analyze the contribution of socioeconomic drivers to air pollution reduction and carbon abatement (PRCA) from the consumption perspective in China's resource-based industries. Additionally, it develops a synergistic emission reduction intensity indicator based on the synergy degree to measure the comprehensive strength of PRCA, thereby evaluating the synergistic efficiency and capability of co-drivers. The findings indicate that the production structure exhibited the most significant impact between 2012 and 2017, contributing 1.48 times more to PRCA in 2015–2017 compared to 2012–2015. Energy efficiency promoted positive synergy during 2012–2015 but subsequently shifted toward negative synergistic emission increases. The final consumption structure had the smallest contribution to PRCA from 2012 to 2017, accounting for only 3.09%. These findings underscore the need for policies tailored to each pollutant and emission source, targeted restructuring of industrial linkages, and stronger regional cooperation.

In this process, reactive calcium oxide (CaO) is utilized during the secondary production stage to facilitate in situ CO₂ mineralization, enabling the formation of a high-performance cement product without compromising durability or strength. The system integrates monoethanolamine (MEA)-based post-combustion CO₂ capture with advanced heat-transfer exchangers, fuel-efficient rotary kilns, and air-preheating technologies. Together, these units enhance thermal integration, reduce kiln fuel demand, and enable the captured CO₂ to be reused directly within clinker formation, thereby closing the carbon cycle within the process itself. The ReAct configuration leverages natural gas and extensive waste-heat recovery from flue gases, reducing overall CO₂ emissions from combustion by approximately 30%–35%, whereas the combined effect of CO₂ capture and in-process mineralization achieves an additional reduction of around 60%. By converting remaining process emissions into mineralized cementitious phases, the system has the potential to achieve net-zero or near-zero CO₂ output from cement production. The approach also yields economic benefits by lowering fuel consumption, improving thermal efficiency, and utilizing resources that would otherwise be lost to the environment.

The technological route for obtaining this fuel from the dry reforming of biogas has received considerable attention from researchers, as it converts the polluting gases CH₄ and CO₂ into synthesis gas (H₂ and CO). In this work, Ni–Al catalysts derived from hydrotalcite were modified with lithium through different methods and were tested in the biogas dry reforming. Coprecipitation, wet and dry impregnation methods were applied, as well as memory effect reconstruction. N₂ adsorption–desorption, XRD, TPR, CO₂-TPD, SEM, and TPO techniques were used for the characterization of the catalysts. For the catalytic tests, a flow rate of 60% CH₄ and 40% CO₂ was used as synthetic biogas. The ramp tests were carried out in the range from 500 to 750°C while the stability tests were carried out at 700°C for 8 h. The results demonstrated that the different Li incorporation methods had a strong effect on the surface, structural and reduction properties of the obtained catalysts. The coprecipitated sample (CP) presented the best performance in the reaction, due to its smaller crystallite size, high basicity and presence of weak, medium and strong basic sites, while the worst results observed for the impregnated samples were attributed to the formation of the LiAlO₂ phase in these samples, resulting in materials with low surface area and large crystallite size.

Although traditional storage techniques are technically mature, persistent concerns continue regarding buoyancy-driven migration, long-term monitoring necessities, and liability. In this context, low-temperature reservoirs, where CO₂ can be trapped as solid hydrates, offer a completely new and possibly safer option to store CO₂. These kinds of settings are found in permafrost regions, deep-ocean sediments, and subsea formations where the temperature is usually below 10°C and the pressure is favorable for hydrate stability. This article evaluates the commercialization potential of hydrate-assisted CO₂ storage in low-temperature reservoirs. Other than concentrating on the technical point of view, which has already been investigated in some laboratory-scale analyses, this article mostly focuses on the commercial relevance from some widespread perspectives. The discussion has been suggested to look at scalability, economic performance, and market positioning. Even though the initial capital costs may be greater because of offshore access and unique injection needs, life-cycle evaluations show that costs could be lower because of less monitoring, lower risk of leaks, and the chance to sell carbon credits in premium markets that value permanency. The technology is still immature, and the most important next step is to do pilot-scale demonstrations. If technically feasible, this CO₂ storage technique emerges as a credible, differentiated, and potentially transformative pathway for secure long-term carbon sequestration in future CCUS portfolios.</p>\u0000 </div>","PeriodicalId":12796,"journal":{"name":"Greenhouse Gases: Science and Technology","volume":"16 3","pages":"501-513"},"PeriodicalIF":3.2,"publicationDate":"2026-07-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148386679","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In such systems, wettability plays a critical role in governing fluid distribution, capillary pressure efficiency, and overall gas storage capacity in underground gas storage (UGS). Therefore, it is crucial to study wettability characteristics under realistic reservoir conditions. While mimicking reservoir conditions in the laboratory is a common practice, researchers have traditionally relied heavily on contact angle measurements despite their well-documented limitations, including sensitivity to surface roughness, contamination, and neglect of pore-scale dynamics. In contrast, capillary pressure curves provide more representative and realistic insights for reservoir simulation modeling. In this study, the porous plate method was employed to measure <i>P</i>_c–<i>S</i>_w relationships to assess wettability alteration in Berea Brown sandstone under depleted reservoir conditions, complemented by surface-level adsorption analyses. Quartz substrates and powdered quartz were treated with low concentrations (0.028 M) of hexanoic, stearic, and lignoceric acids dissolved in toluene, with adsorption characterized using time-of-flight secondary ion mass spectrometry (TOF–SIMS) and Fourier transform infrared (FTIR) spectroscopy. Both techniques confirmed the adsorption of organic acids, with adsorption intensity increasing with alkyl chain length. However, the <i>P</i>_c–<i>S</i>_w curves of six sandstone core samples (BB1–BB6) revealed no significant shifts after treatment. In addition, residual water saturations remained within experimental uncertainty (49%–62%), indicating that the cores retained their initial water-wet state. These results highlight a critical discrepancy: while contact angle measurements reported in the literature suggest wettability alteration even at minimal organic acid concentrations, capillary pressure analyses demonstrate that such concentrations are insufficient to induce measurable pore-scale wettability changes in low-permeability sandstone. This study emphasizes the importance of capillary pressure curve measurements over contact angle or surface adsorption analyses for realistic evaluation of wettability alteration, providing more reliable insights for assessing CO₂ and H₂ storage performance in depleted sandstone reservoirs.</p>\u0000 </div>","PeriodicalId":12796,"journal":{"name":"Greenhouse Gases: Science and Technology","volume":"16 3","pages":"410-419"},"PeriodicalIF":3.2,"publicationDate":"2026-07-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148386690","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Aspen Adsorption is widely applied for simulating and optimizing fixed-bed adsorption processes, providing an effective platform for designing and evaluating CO₂ capture systems. In this study, the adsorption-based fixed-bed capture unit is developed for CO₂ capture using Aspen Adsorption.
