Kinetics of the Formation and Dissociation of Gas Hydrates from CO 2 -CH 4 Mixtures
Sequestration of carbon dioxide (CO 2 ) in the form of its hydrates in natural methane (CH 4 ) hydrate reservoirs, via CO 2 /CH 4 exchange, is an attractive pathway that also yields valuable CH 4 gas as product. In this paper, we describe a macroscale experiment to form CO 2 and CH 4 -CO 2 hydrates,...

Sequestration of carbon dioxide (CO 2 ) in the form of its hydrates in natural methane (CH 4 ) hydrate reservoirs, via CO 2 /CH 4 exchange, is an attractive pathway that also yields valuable CH 4 gas as product.
