Adsorption-Driven Preferential Crystallization and Growth Direction Switching of Methane Hydrates within Confined Porespaces
This Communication addresses two unresolved pivots in gas storage using adsorption–hydration synergetic technology (AHST): (i) how gas adsorption influences the distribution of preadsorbed water and (ii) how hydrate crystallization and growth occur within confined porespaces. Through in situ high-resolution visualization, the competitive adsorption supremacy of methane over preadsorbed water was clearly demonstrated. Additionally, a dual water migration phenomenon was identified, including adsorption-driven water displacement and hydration-induced water remigration. Accordingly, the preferential hydrate crystallization within confined porespaces was uncovered along with the delineation of methane hydrate growth pathways. These pathways exhibited a redirectional growth trajectory, characterized by initial inward growth followed by eventual outward expansion. These insights can facilitate the optimization of pore architecture design and preadsorbed water loading, providing theoretical support for the application of AHST.
期刊介绍：
The aim of Crystal Growth & Design is to stimulate crossfertilization of knowledge among scientists and engineers working in the fields of crystal growth, crystal engineering, and the industrial application of crystalline materials.
Crystal Growth & Design publishes theoretical and experimental studies of the physical, chemical, and biological phenomena and processes related to the design, growth, and application of crystalline materials.
