The study visualizes supercritical CO₂ (scCO₂) dissolution into brine in porous media under high temperature and pressure by using micro-computed tomography. The dynamic evolution of interphase interface of CO₂-brine was innovatively investigated in three dimensions and quantified over time. The conclusions showed that the residual saturation of CO₂ was negatively correlated with the flow rate. Five distinct forms of CO₂ cluster evolution were identified, resulting in the non-uniform spatial distribution of the CO₂-brine interface. Then a novel classification of four interface types between CO₂ and brine was proposed and it exhibits non-monotonic evolution due to the combined effects of pore filling and snap-off events. Both local and spatial mass transfer coefficients (MTC) were calculated based on the quantified interfacial area, showing strong heterogeneity along porous media. Additionally, the local MTC of scCO₂ was found to be from 10⁻¹⁰ to 10⁻⁶ m/s, with a broader range of magnitudes compared to its gaseous state (10⁻⁹ to 10⁻⁸ m/s). Finally, the mass transfer model for trapped-phase dissolution in porous media is extended on the basis of the Sherwood number, Reynolds number and Schmidt number. Understanding the evolution of these interfaces and models of dissolution mass transfer of trapped phase can aid in predicting CO₂ behavior in saline aquifers, optimizing storage strategies, and ensuring CO₂ dissolution trapping and long-term storage stability.</div></div>","PeriodicalId":100568,"journal":{"name":"Gas Science and Engineering","volume":"143 ","pages":"Article 205717"},"PeriodicalIF":0.0,"publicationDate":"2025-07-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144587709","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

One promising approach is the dry reforming of methane (DRM), which converts methane (CH₄) and carbon dioxide (CO₂)—both major greenhouse gases—into valuable syngas (a mixture of hydrogen and carbon monoxide). However, the development of cost-effective and sustainable catalysts that can operate efficiently while utilizing biomass waste remains a significant challenge. This study investigates the development of cost-effective and durable nickel-based catalysts supported on activated carbon derived from date palm leaves biomass waste. The catalysts were synthesized via a wet impregnation method and characterized using various techniques including XRD, BET, SEM, TEM, FT-IR, H₂-TPR, CO₂-TPD, NH₃-TPD, TGA, Raman analysis and XPS. The catalytic performance of the synthesized catalysts for DRM was evaluated at a temperature of 750 °C for 12 h using fixed-bed reactor. Results demonstrate that the activated carbon support significantly influences the catalysts' activity and stability. In particular, Ni-doped modified activated carbon from date palm leaves exhibited superior performance, achieving high CH₄ (41 %) and CO₂ (75 %) conversion, compared to commercial activated carbon derived from coconut shell. The catalyst also showed good resistance to coking and sintering, making it a promising candidate for DRM.

Geological H₂ storage based on adsorption haven been well-identified but the studies on compressibility-based elastic storage of H₂ remain limited. The objective of this study is to evaluate different compressibilities of unconventional gas shale and related implications on geological hydrogen storage. Laboratory measurements were conducted to estimate the compressibilities of shale and adsorption capacity of H₂ in shale. Theoretical consideration on elastic storage of H₂ through the coefficient of fluid content by a poroelastic framework was developed to compare with the H₂ geo-storage based on adsorption mechanism. The results show that shale deforms linearly with gas pressure for helium, while more pronounced compression can be observed with the exposure of H₂. The modeled coefficient of fluid content is well able to predict the results calculated from measured data. By extending the framework of fluid content, the elastic storage capacity of H₂ was estimated as 0.0526 mmol/g at 8.5 MPa while the excess adsorption amount of H₂ in shale was measured as 0.03043 mmol/g at the same pressure. The results reveal that the compressibility-based elastic storage of H₂ in unconventional gas shale is not negligible due to its large potential with continuous gas injection. Additionally, strain hysteresis effects were observed after H₂ injection and depletion in shale, which is potentially caused by permanent structural alteration of shale. This structural variation promotes the elongation of gas pathway that enhances the permeability and further injectivity and recoverability of H₂.</div></div>","PeriodicalId":100568,"journal":{"name":"Gas Science and Engineering","volume":"142 ","pages":"Article 205715"},"PeriodicalIF":0.0,"publicationDate":"2025-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144549754","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study utilizes a microfluidic chip to investigate the intricate dynamics of gas hydrate formation and decomposition, focusing on the comparison between conventional formation methods and a novel freeze-melting pathway. By examining induction times, formation rates, hydrate morphology, and spatial distribution, the influence of the formation pathway on hydrate growth kinetics is revealed. Real-time, phase-resolved imaging demonstrates that ice-mediated nucleation leads to rapid hydrate formation during melting, while freezing liquid water creates mass transfer bottlenecks that slow the process. In the assessment of decomposition, multiphase interactions, including depressurization, thermal stimulation, and unsaturated water injection, govern dissociation kinetics. Notably, free gas release rates during depressurization and thermal stimulation significantly exceed those of dissolved-phase gas transport, highlighting the dominant role of phase dynamics in hydrate dissociation. Quantitatively, the dissociation rate of hydrate in contact with the free gas phase during depressurization is approximately 12 times higher than that in contact with the liquid phase, and this difference becomes even more pronounced during thermal stimulation, where the gas-phase dissociation rate is about 48 times higher than the liquid-phase counterpart. The injection of unsaturated water induces gradual dissolution, with the dissolution rate inversely related to chip thickness, which is a key factor in hydrate saturation and directly proportional to the injection rate. When the chip thickness increased from 30 μm to 50 μm, the decomposition time increased to 324 % of its original time. Under the same chip thickness, increasing the injection flow rate from 0.1 ml/min to 0.5 ml/min and from 0.5 ml/min to 1 ml/min reduced the decomposition time to 33.3 % and 67.1 % of the original time, respectively. Hydrates formed via the freeze-melting pathway exhibit a looser structure and faster dissolution compared to the denser, conventionally formed hydrates. These findings provide valuable insights into optimizing hydrate production and preventing hydrate reformation in subsea infrastructure. They also suggest new approaches for refining hydrate extraction strategies and controlling subsurface flow. Although promising, scaling these microfluidic insights to field conditions presents challenges, such as size effects on fluid behavior. Future research will focus on multi-scale simulations to bridge microfluidic observations with field-scale dynamics, paving the way for improved energy production and environmental management.</div></div>","PeriodicalId":100568,"journal":{"name":"Gas Science and Engineering","volume":"142 ","pages":"Article 205709"},"PeriodicalIF":0.0,"publicationDate":"2025-06-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144510929","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study investigated the adsorption process and thermodynamic parameters of kerogen-water systems using water vapor adsorption (WVA) experiments at variable temperatures (288.15–308.15 K) on three kerogen samples. Molecular dynamics (MD) simulations are carried out to evaluate thermodynamic interactions of CH₄ in kerogen-water systems of varying water content. Mechanistically, our observations reveal that adsorption of water onto -kerogen is initially a spontaneous endothermic process, which transitions to an exothermic process when the relative humidity (RH) reaches 80 %. During primary adsorption, as the adsorption amount increases, the heat of adsorption remains relatively stable, spontaneity decreases, and the rate of entropy increase slows down. During secondary adsorption, the heat of adsorption gradually shifts from endothermic to exothermic as the adsorption amount increases, with rapidly decreasing spontaneity and entropy. A mixed-order model is identified as an optimal model to resolve the adsorption kinetics of the water-kerogen system. The rate of water molecule adsorption on the kerogen surface is substantially higher than its diffusion rate.
