Gas storage device and method for releasing gas

摘要

Storing gaseous molecules into a sorbent at normal conditions and subsequently releasing the targeted molecules from the sorbent, comprises: loading the sorbent in an anhydrous state with the gaseous molecules; storing at an ambient pressure under a moisturizing condition; directing the gaseous molecules into the sorbent; adsorbing water molecules from the sorbent, and releasing the pre-adsorbed gaseous molecules; and providing the heat of adsorption released during the adsorption of water molecules to carry out desorption of the released gaseous molecules. Storing gaseous molecules into a sorbent at normal conditions and subsequently releasing the targeted molecules from the sorbent, comprises: loading the sorbent in an anhydrous state with the gaseous molecules; storing at an ambient pressure under a moisturizing condition; directing the gaseous molecules in water vapor or liquid state into the sorbent for the targeted release; adsorbing water molecules from the sorbent, and releasing the pre-adsorbed gaseous molecules through the high adsorption of water molecules, where the gaseous molecules escape from the sorbent under a higher or a constant pressure than the ambient pressure; and providing the heat of adsorption released during the adsorption of water molecules to carry out desorption of the released gaseous molecules.
