Ammonia salts as regenerable CO
View Patent ↗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.
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.
