Instant formation of many gas hydrates near 200K

What is it about?

This represents a step towards very rapid formation of icelike substances that trap significant amounts of gases such as methane and carbon dioxide. The substances have long been considered as potentially useful in the trapping of these gases, particularly from smokestacks, and in storage as for transformation purposes. Now we have shown that they can be formed much more rapidly using all vapor mixtures. The current limitation is the need for inclusion of excessive catalyst.

Why is it important?

The gas hydrate formation rate as particles in aerosols is orders of magnitude greater that using previous methods. This opens up the possibility of modifying the method further to make it a practical approach to capture and storage of gases such as methane, carbon dioxide, acetylene etc. . Current limitations are the temperature range (<200K) and the need for more catalyst than desired. This article addresses these problems while creating a new index for gases reflecting competitive uptake.
