Abstract

The present method describes the absorbing and desorbing of a gaseous reactant on a solid reactant. The solid reactant is an ammonia salt selected from the group consisting of alkali ammonium salts, alkali ammonium earth salts or a combination thereof.

Claims (11)

1. A method comprising:

absorbing and desorbing CO 2 on a solid reactant wherein the solid reactant is Li(NH 3 ) 6 Cl,

wherein the absorption percentage of the gaseous reactant upon the solid reactant is at least 20% more effective when compared to solid reactants absent ammonia,

2. A method comprising:

absorbing CO 2 on a solid reactant to produce a sequestered carbon dioxide compound and desorbing CO 2 from the sequestered carbon dioxide compound

wherein the solid reactant is Li(NH 3 ) 6 Cl,

wherein the absorption percentage of the gaseous reactant upon the solid reactant is at least 20% more effective when compared to solid reactants absent ammonia,

wherein, a sequestered carbon dioxide compound is manufactured from the process of combining LiCl with NH 3 to produce the solid reactant of Li(NH 3 ) 6 Cl; and

absorbing CO 2 to the solid reactant to produce a sequestered carbon dioxide

compound selected from the group consisting of: Li(NH 3 ) 6-x (CO 2 ) x Cl and, Li(NH 3 ) 6 Cl x CO 2 , and

wherein the desorbing of the gaseous reactant on the solid reactant is an endothermic reaction requiring enough heat to release gaseous CO 2 from the sequestered carbon dioxide compound.
