Abstract

Natural gas hydrate has tremendous gas storage capacity; natural gas hydrate can be used to store and transport energy. The current problem faced is how to improve the hydrate formation rate and storage capacity, and form continuously. Compared to the pure water and SDBS solution, the ionic solution [HMIPS]OTs made by the team was the excellent additive and ensured the best reaction concentration range. Specific effects of different additives on hydrate formation were summarized; hydrate formation mechanism of additives was expounded. Considering the investment cost, operation cost, simple and stable operation of different surfactants, it is thought that the study of different additives mechanisms and developing the new efficient additive have the important value.
