“…Gas hydrates, or clathrates, are nonstoichiometric compounds comprising minute gas molecules like methane, carbon dioxide, and propane enclosed within a lattice of water molecules. Research has demonstrated that clathrates possess a significant storage capability, with 1 cm 3 of hydrate able to accommodate up to 150 m 3 of natural gas, surpassing the storage efficiency of compressed or liquid natural gas under secure conditions. − Due to its expandable storage volume, the gas hydrates have been utilized for gas separation with a lower energy pathway as compared to convection methods in the isolation of xenon from its trinary combinations with krypton and argon . An examination of the practicality of employing gas hydrate for biogas storage, a sustainable energy source with a minimal environmental footprint, revealed that two economically viable methods can be employed to convert biogas into biomethane .…”

Increasing energy demands have opened research channels into alternate areas to explore viable options for energy storage. This has led to investigations into the use of gas hydrate technology, specifically derived from methane gas, for diverse energy applications, such as gas storage and gas transportation. In this study, the kinetics of CH 4 hydrate formation in (0.1, 0.2, 0.5, 1.0, and 1.2 wt %) CuO and Al 2 O 3 nanoparticles, graphene nanoplatelets, and ZnO microparticles in the presence of 0.05 wt % sodium dodecyl sulfate (SDS) were measured experimentally. The experimental measurements were conducted in a 52 cm 3 equilibrium cell at a pressure of 4.66 MPa and a temperature of 275.8 K. The kinetic parameters under investigation included the induction time, storage capacity, water conversion, rate of gas uptake, and gas consumption. Results show that the inclusion of nanoparticles in the experiments decreased the induction time from 18.4 min with deionized water to 1.0 min with 0.1 wt % CuO + 0.05 wt % SDS while the induction period increased to 20.7 min with 1.2 wt % ZnO + 0.05 wt % SDS microparticles. A maximum storage capacity of 28.5 (v/v) was obtained using 0.1 wt % CuO + 0.05 wt % SDS. The highest gas uptake rate recorded was 8.9 × 10 −4 mol gasmol water −1 min −1 , achieved with the combination of 0.5 wt % CuO + 0.05 wt % SDS. Overall, the parameters investigated in this study indicated a significant enhancement in the rate of hydrate formation with the inclusion of nanoparticles.

“…Gas separation and purification processes hold paramount significance in a wide array of applications, encompassing energy production and food packaging. − The efficient separation of alkenes from alkanes, such as ethylene from ethane and propylene from propane, is critical to meet their substantial global demand. , Similarly, the separation of xenon/krypton (Xe/Kr) finds utility in fields like medical imaging and insulation. − Traditional chemical separation processes, such as distillation and drying, are energy-intensive, accounting for a significant portion of global energy consumption . This has contributed to many environmental issues, including an increase in the atmospheric CO 2 concentration. − Therefore, the development and implementation of non-thermal separation processes, like adsorption-based separation, offer a promising avenue to reduce energy consumption and mitigate CO 2 emissions. ,, …”

Metal−organic frameworks (MOFs) have demonstrated their versatility in a wide range of applications, including chemical separation, gas capture, and storage. In industrial adsorption processes, MOFs are integral to the creation of selective gas adsorption fixed beds. In this context, the assessment of their separation performance under relevant conditions often relies on breakthrough experiments. One aspect frequently overlooked in these experiments is the shaping of MOF powders, which can significantly impact the accuracy of breakthrough results. In this study, we present an approach for immobilizing MOF particles on the surface of glass beads (GBs) utilizing trimethylolpropane triglycidyl ether (TMPTGE) as a binder, leading to the creation of MOF@GB materials. We successfully synthesized five targeted MOF composites, namely, SIFSIX-3-Ni@GB, CALF-20@GB, UiO-66@GB, HKUST-1@GB, and MOF-808@GB, each possessing distinct pore sizes and structural topologies. Characterization studies employing powder X-ray diffraction and adsorption isotherm analyses demonstrated that MOFs@GB retained their crystallinity and 73−90% of the Brunauer−Emmett−Teller area of their parent MOFs. Dynamic breakthrough experiments revealed that, in comparison to their parent MOFs, MOF@GB configurations enhanced the accuracy of breakthrough measurements by mitigating pressure buildup and minimizing reductions in the gas flow rate. This work underscores the significance of meticulous experimental design, specifically in shaping MOF powders, to optimize the efficacy of breakthrough experiments. Our proposed strategy aims to provide a versatile platform for MOF powder processing, thereby facilitating more reliable breakthrough experiments.
