Method of conducting an absorption or desorption reaction between a gas and a solid in which the reaction medium is formed using a powdery solid having a compaction between 5 and 60% of the optimum compaction of the reaction without graphite. |
|
DETAILED DESCRIPTION We claim: 1.
A method of conducting an absorption or desorption reaction between a gas and a solid, said solid being formed by one or more salts in powdery form, in the presence of expanded graphite, in which method the reaction medium comprises expanded graphite in a positive amount up to 60% by weight, characterized in that, in order to form the reaction medium, a powdery solid is used having a compaction between 5 and 60% of the optimum compaction of the reaction without graphite, wherein said optimum compaction is the compaction value for which the energy density is a maximum for the reaction without graphite.
2.
Method according to claim 1, in which the percentage of expanded graphite is between 20 and 25% included by weight, characterized in that the compaction of the salt is chosen in a range between 20 and 60% of the optimum compaction.
3.
Method according to claim 1, in which the percentage of expanded graphite is between 25 excluded and 35% included by weight, characterized in that compaction of the salt is chosen between 15 and 55% of the optimum compaction.
4.
Method according to claim 1, in which the percentage of expanded graphite is between 35 excluded and 40% included, characterized in that compaction of the salt is chosen between 15 and 50% of the optimum compaction.
5.
Method according to claim 1, in which the percentage of expanded graphite is between 40 excluded and 45% included by weight, characterized in that compaction of the salt is chosen between 10 and 50% of the optimum compaction.
6.
Method according to claim 1, in which the percentage of expanded graphite is between 45 excluded and 50% included by weight, characterized in that compaction of the salt is chosen between 10 and 45% of the optimum compaction.
7.
Method according to claim 1, in which the expanded graphite percentage is between 50 excluded and 60% by weight, characterized in that compaction of the salt is chosen in a range between 5 and 40% of the optimum compaction.
Description:
The present invention relates to a method of conducting an absorption or desorption reaction between a gas and a solid, this solid being formed by a salt or a mixture of salts capable of reacting with the gas while giving an absorption reaction or conversely a desorption reaction, these reactions taking place in the presence of expanded graphite
