“…The development and utilization of gas hydrates has become essential to ensuring national energy security, promoting deep sea strategy, and achieving the double carbon goals. Gas hydrates are a non-chemometric cage-like crystalline substance formed by water and methane gas, known as combustible ice [3,4], making it a very clean energy source. Based on the advantages of mild formation conditions, high gas content, and safe storage and transportation [5,6], related scholars have proposed the safe storage and transportation of methane gas released via hydrate mining through hydration technology so as to alleviate energy tension [7][8][9][10][11][12].…”

To improve gas hydrate storage and transportation technology, ferromagnetic intermetallic compound NiMnGa particles with martensitic transformation endothermics were used to form micro/nanofluids with sodium dodecyl sulfate (SDS) to further strengthen the gas hydration process. In this work, the kinetic process of gas hydration in NiMnGa fluids with different concentrations (0, 0.1, 1, 2, and 3 wt.%) was investigated using a rotating magnetic field gas hydration separation experimental setup. The results show that the induction time of the 3 wt.% NiMnGa system was shortened by 98.3%, the gas consumption was increased by 50.5%, and the gas consumption rate was increased by 351.9% compared with the SDS system. Therefore, it is inferred from the mass transfer that NiMnGa micro/nanofluids can accelerate the formation of hydrates.
