摘要
Abstract
It is a hot topic to capture carbon dioxide by forming hydrate.However its application is limited due to the harsh formation conditions of carbon dioxide hydrate and low yield rate of hydrate.Using additives can improve hydrate separation effect.The advances in carbon dioxide hydrate kinetic additives at home and abroad were introduced and analyzed from two aspects,the enhancement of kinetic additives on carbon dioxide hydrate generation and the mechanism of additives promoting carbon dioxide formation.For the enhancement of kinetic additives,the effects of different types of kinetic additives on hydrate formation and the inhibitory effect on hydrate formation at high concentrations were discussed.In terms of the mechanism of additives promoting carbon dioxide formation,the recent research results were summarized and the shortcomings of the mechanism were pointed out.In addition,the lack of carbon dioxide hydrate kinetic additives and the future development of future researches were also discussed.The relationship between the effect of kinetic additives on hydrate formation and its containing groups needs to be further studied; secondly,there is no unified conclusion about the mechanism of hydrate formation by kinetic additives,which may be due to the fact that the current study focuses on the change in the external form of the hydrate and does not explore the change in the internal structure of the hydrate,so the effect of additives on the hydrate internal structure changes needs to be further studied.关键词
