摘要
自然界中的天然气水合物具有巨大的能源潜力,同时水合物技术在气体储运、海水淡化、气体分离、污水处理等领域也有很广的应用前景,但水合物一些固有的性质(如较低的水合物形成速率和严苛的水合物形成条件)阻碍了这些技术的商业化。因此,研究者尝试将纳米技术与水合物技术相结合,利用纳米颗粒促进或者抑制水合物形成,服务于水合物安全高效钻采,并推动水合物技术应用。综述了纳米颗粒及其流体的基本性质、分散方法和对水合物热力学和动力学方面的影响,指出了当前研究存在的问题,并提出了今后纳米颗粒作为水合物添加剂的研究方向及在水合物勘探和开发过程中潜在的应用。
Natural gas hydrates are potentialenergy resources. Meanwhile, hydrate technologies have a wide range of potential applications in gas storage and transportation, seawater desalination, gas separation, sewage treatment and other fields. However, some inherent properties of hydrates (such as the low formation rate and harsh conditions for hydrate formation) hinder the commercialization of these applications. Therefore, researchers try to combine nanotechnologies with hydrate technologies, using nanoparticles to promote or inhibit hydrate formation, so as to serve the safe and efficient drilling and exploitation of the hydrate, and promote the applications of hydrate technologies. This paper reviews the basic properties of nanoparticles and their corresponding nanofluids, dispersion methods and their effects on the thermodynamics and dynamics for hydrate formation. Moreover, the paper points out the existing problems about above research and the possible research directions of nanoparticles as hydrate additives and their potential applications in the exploration and development of hydrates.
