摘要：

Gas hydrate extraction by CO2 replacement and gas storage and transportation by gas hydrate method are the focus of research by scientists at present, and the stability of gas hydrate is very important for its long-term storage and long-distance transportation. Therefore, it is necessary to improve the storage capacity of carbon dioxide hydrate and to seek the high efficient and stable storage conditions of hydrate. However, scientists have found that some accelerators can make hydrate stored for a long time under mild conditions. This paper analyzes the influence of the “self-protection”effect on the stability of carbon dioxide hydrate from the three mechanisms, temperature, pressure, particle size, accelerator and hydrate form, and proves that gas hydrate generally has good stability under the conditions of 260~270K and 0.1~0.4MPa. In addition, the same accelerators have different effects on the stability of hydrate above and below freezing point. Finally, the research direction of hydrate stability in the future is pointed out. © 2021, Materials China. All rights reserved.
