Dear Class,
The article on Green Chemistry and Green Engineering will serve to make up one of the two classes we missed. The article is from page 271 to page 293 but you can read up to page 285, if you wish. If you haven’t taken a science course at Hunter, I think that what chemistry there is was taught to you by your HS chem teacher. (Make him or her proud.) There will be two questions on the final from this paper.

Recovery of Methane from Gas Hydrates Intercalated within Natural Sediments Using CO2 and a CO2/N2 Gas Mixture

Abstract: The direct recovery of methane from massive methane hydrates (MHs), artificial MH-bearing clays, and natural MH-bearing sediments is demonstrated, using either CO2 or a CO2/N2 gas mixture (20 mol% of CO2 and 80 mol% of N2, reproducing flue gas from a power plant) for methane replacement in complex marine systems. Natural gas hydrates (NGHs) can be converted into CO2 hydrate by a swapping mechanism. The overall process serves a dual purpose: it is a means of sustainable energy-source exploitation and greenhouse-gas sequestration. In particular, scant attention has been paid to the natural sediment clay portion in deep-sea gas hydrates, which is capable of storing a tremendous amount of NGH. The clay interlayer provides a unique chemical-physical environment for gas hydrates. Herein, for the first time, we pull out methane from intercalated methane hydrates in a clay interlayer using CO2 and a CO2/N2 gas mixture. The results of this study are expected to provide an essential physicochemical background required for large-scale NGH production under the seabed.
