  • Patent number: 8578702
    Abstract: A method of storing and delivering ammonia and the use of electromagnetic radiation for desorption of ammonia from a chemical complex. Solid metal ammine complexes are applied for safe and high-density storage of ammonia to be released for use as reducing agent in selective catalytic reduction of NOx in exhaust gases. The compositional formula of the metal ammine complexes is M(NH3)nXz, where M2+ represents one or more metal ions capable of binding ammonia, X represents one or more anions, n is the coordination number (from 2 to 12), and z the valency of the metal ion (and thus the total number of compensating anion charges). Ammonia is released non-thermally by photon-activation using electromagnetic irradiation of the complex bond between ammonia coordinated to the metal ion.

  • Patent number: 8551219
    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.

  • Publication number: 20120039788
    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 ne

  • Publication number: 20100293927
    Abstract: Solid metal ammine complexes are applied for safe and high-density storage of ammonia to be released for use as reducing agent in selective catalytic reduction of NOx in exhaust gases. The compositional formula of the metal ammine complexes is M(NH3)nXz, where MZ+ represents one or more metal ions capable of binding ammonia, X represents one or more anions, n is the coordination number (from 2 to 12), and z the valency of the metal ion (and thus the total number of compensating anion charges). Ammonia is released by generating a reduced gas-phase pressure of ammonia inside the container, which is below the equilibrium desorption pressure of ammonia at the operating temperature of the storage material thus enabling the unit to be operated is a safe manner with lower operating temperature and pressure.

  • Patent number: 7304486
    Abstract: The multi-point probe comprises a supporting body defining a first surface, a first multitude of conductive probe arms each of the probe arms defining a proximal end and a distal end being positioned in co-planar relationship with the first surface of the supporting body. The probe arms are connected to the supporting body at the proximal ends thereof and have the distal ends freely extending from the supporting body, giving individually flexible motion to the first multitude of probe arms. The probe arms originate from a process of producing the probe arms on a wafer body in facial contact with the wafer body and removal of a part of the wafer body providing the supporting body and providing the probe arms freely extending therefrom. The multi-point probe further comprises a third multitude of tip elements extending from the distal end of the first multitude of probe arms. The tip elements originate from a process of metallization of electron beam depositions on the probe arms at the distal ends thereof.
