A new approach to gas hydrate modelling
Guang-Jin Chen,Tian-Min Guo +1 more
TL;DR: In this paper, a two-step hydrate formation mechanism is proposed for gas hydrate, which consists of a quasi-chemical reaction process to form basic hydrate and an adsorption process of smaller gas molecules in the linked cavities of basic hydrates.
