    Abstract: A process for saturating a solid material capable of binding ammonia by ad- or absorption and initially free of ammonia or partially saturated with ammonia comprises treating said solid material under a pressure and associated temperature located on the vapor pressure curve of ammonia with an amount of liquid ammonia sufficient to saturate said solid material and an additional amount of a cooling agent selected from liquid ammonia, liquid or solid CO2, hydrocarbons and hydrohalocarbons that have a higher vapour pressure than ammonia, ethyl ether, methyl formate, methyl amine and ethyl amine, such that |Qabs|≦|Qevap|+Qext, wherein Qabs is the amount of heat released from said solid material when it absorbs ammonia from the liquid phase thereof to the point where it is saturated with ammonia, Qevap is the amount of heat absorbed by said cooling agent when it evaporates, and Qext is the amount of heat exchanged with the surroundings and is positive, if heat is removed from the process by external cooling, and negative, if heat is added to the process from the surroundings.

    Abstract: In a method of storing and releasing gaseous ammonia from solid storage materials a first solid storage material (14) capable of releasing ammonia by desorption in a first container (10) and a second solid storage material (24) capable of ad- or absorbing ammonia reversibly and having a higher affinity for ammonia than the first storage material (14) in a second container (20) smaller than said first container (10) are in fluid communication. The pressure in at least the first container (10) is kept below the equilibrium pressure between ammonia and the storage material contained therein by means of a pump (28). When the pressure in the first container (10) is below a pressure threshold where the first storage material (14) does not release an amount of ammonia required by an ammonia consuming device connected with the containers via the vacuum pump (28), the second storage material (24) is heated such that the ammonia pressure of the second material (24) is higher than the ammonia pressure of the first material (14). The ammonia released by the second material (24) is continuously pumped off so as to deliver sufficient ammonia to said ammonia consuming unit. A device for carrying out the method is also described.
