Applications of Solid State NMR in the Studies of Gas Hydrate
摘要
Abstract
Gas hydrate is a clathrate compound formed from gas and water under low temperature and high pressure. So far, three types of crystal structure (i. e. I, II and H) have been found for natural gas hydrate around the world. Solid state NMR provides an important tool for structure characterization of gas hydrate and for quantitative measurement of hydration number and cage occupancy. In this paper, the principles and applications of solid state NMR techniques in studying gas hydrate were reviewed. Emphasis was given on the progresses in structural characterization of gas hydrates, identification of gas molecules and studies on structure transform, as well as the in situ monitoring of hydrate formation and dissociation. The experimental techniques and conditions for solid state NMR studies of gas hydrate were also discussed.关键词
