    Abstract: An integrated purification method and an integrated purification system for an industrial exhaust gas containing cyanides, hydrocarbons and NOx. The method comprises the steps of: 1) subjecting the exhaust gas containing pollutants such as cyanides, hydrocarbons and nitrogen oxides (NOx) to a gas-liquid separation device (1) to separate the free fluid, then mixing with the air blown by the air blower (201, 202), and preheating by the heating unit; 2) the mixture entering into the selective catalytic combustion (SCC) reactor (5) for the selective catalytic combustion reaction to convert harmful substances into CO2, H2O and N2, the catalysis being performed in two stages: the earlier stage is catalyzed by supported molecular sieve catalyst, and the latter stage is catalyzed by supported precious metal catalyst; and 3) the gas came out from the SCC reactor (5) entering into the heating unit to recover the heat, and then the purified exhaust gas being discharged directly through the chimney (6).

  • Patent number: 10267230
    Abstract: A fuel conditioning apparatus for de-oxygenating a liquid hydrocarbon fuel has a catalyst portion which, in turn, has an inlet portion and an outlet portion. A hydrocarbon fuel stream is fed through the inlet portion and into the catalyst portion where it passes over a catalytically active component. The catalytically active component promotes the reaction of the fuel with the dissolved oxygen in the fuel stream, converting it into less chemically reactive forms and thereby reducing the fuel's propensity to form carbonaceous deposits.

  • Patent number: 10245577
    Abstract: Electrokinetic devices and methods are described with the purpose of propelling a dielectric fluid medium, usually air, and optionally collecting assayable agents from the medium. Electrokinetic flow may be induced by the use of plasma generation at high voltage electrodes and consequent transport of charged particles in an electric voltage gradient. The generation of electrokinetic flow has the disadvantage that certain amounts of ozone may be formed in the process. Methods and devices are described herein where suitable catalysts can be combined with the electrokinetic device in such a way that ozone is effectively destroyed in the effluent flow without compromising the amount of flow.

    Abstract: An object of this invention is to provide an atmosphere-cleaning device for vehicles that is capable of restoring the function of an ozone purifying body carried by a vehicle component. Mud, dust, snow-melting agents as well as SOx and NOx are scattered into the atmosphere as a result of being swirled up by a preceding vehicle or due to weather and climate conditions. When such extraneous substances adhere or the like to an ozone purifying body, the purification sites thereof are clogged and the ozone purification function deteriorates. Therefore, when a predetermined removal implementation condition is established, control is executed to inject cleaning liquid from an injector to enhance the fluidity of the extraneous substances and wash the extraneous substances away. The function of the ozone purifying body can thereby be restored.

    Abstract: Metal-organic frameworks of the family M2 (2,5-dioxido-1,4-benzenedicarboxylate) wherein M=Mg, Mn, Fe, Co, Cu, Ni or Zn are a group of porous crystalline materials formed of metal cations or clusters joined by multitopic organic linkers that can be used to isolate individual gases from a stream of combined gases. This group of adsorbant materials incorporates a high density of coordinatively-unsaturated MII centers lining the pore surfaces. These adsorbents are particularly suited for selective carbon dioxide/monoxide adsorption via pressure swing adsorption near temperatures of 313 K since they selectively adsorb carbon dioxide at high pressures in the presence of hydrogen, and desorb carbon dioxide upon a pressure decrease. The redox-active FeII centers in Fe2(dobdc) can be used for the separation of O2 from N2 and other separations based on selective, reversible electron transfer reactions.

  • Patent number: 8323602
    Abstract: Carbon monoxide (CO) may be removed from flue gas generated by oxyfuel combustion of a hydrocarbon or carbonaceous fuel, by contacting the flue gas, or a CO-containing gas derived therefrom, at a first elevated temperature, e.g. at least 80° C., and at a first elevated pressure, e.g. at least 2 bar (0.2 MPa), with at least one catalyst bed comprising a CO-oxidation catalyst in the presence of oxygen (O2) to convert CO to carbon dioxide and produce carbon dioxide-enriched gas. The carbon dioxide produced from the CO may be recovered from the carbon dioxide-enriched gas using conventional carbon dioxide recovery techniques. NO in the flue gas may also be oxidized to nitrogen dioxide (NO2) and removed using conventional NO2 removal techniques, or may be reduced in the presence of a reducing gas to nitrogen (N2) which does not have to be removed from the gas.

  • Publication number: 20120288428
    Abstract: The disclosure provides methods and systems for sequestering and/or reducing sulfur oxides, nitrogen oxides and/or carbon dioxide present in industrial effluent fluid streams. A solid particulate material comprising a slag component, a binder component (distinct from the slag component), and optionally water is formed and then contacted with the effluent fluid stream to reduce at least one of the sulfur oxides, nitrogen oxides, and/or carbon dioxide. The contacting of the effluent stream may occur in a packed bed reactor with the solid dry particulate material. Methods of reducing pollutants from exhaust generated by combustion sources, lime and/or cement kilns, iron and/or steel furnaces, and the like are provided.

  • Patent number: 8246719
    Abstract: Method for processing an article comprising mixed conducting metal oxide material. The method comprises contacting the article with an oxygen-containing gas and either reducing the temperature of the oxygen-containing gas during a cooling period or increasing the temperature of the oxygen-containing gas during a heating period; during the cooling period, reducing the oxygen activity in the oxygen-containing gas during at least a portion of the cooling period and increasing the rate at which the temperature of the oxygen-containing gas is reduced during at least a portion of the cooling period; and during the heating period, increasing the oxygen activity in the oxygen-containing gas during at least a portion of the heating period and decreasing the rate at which the temperature of the oxygen-containing gas is increased during at least a portion of the heating period.

  • Publication number: 20120134904
    Abstract: The invention relates to a method for the deoxygenation in a chemical loop of smokes resulting from oxidation-combustion reactions, that comprises: a first step during which the smokes are stripped from their oxygen by trapping the same by the oxidation of an oxygen-carrier material, thus producing a main flow of smokes with a reduced oxygen content; and a second step for also producing smokes that can join the main smoke flow and during which the material oxidised during the first step is reduced and regenerated by reaction with the fuel in order to be used again during said step. The invention also relates to an apparatus for implementing said method.

  • Publication number: 20120100055
    Abstract: The disclosure provides for oxygen separation from air by utilizing an initial oxygen carrier which undergoes an endothermic reduction reaction to produce a carrier product and gaseous oxygen. The gaseous oxygen is withdrawn, and the carrier product is subsequently further reduced with a fuel in a combustion process, releasing heat and generating a oxygen acceptor. The oxygen acceptor is oxidized in an exothermic reaction. The method thus couples the exothermic oxidation reaction, the endothermic reduction reaction, and the chemical energy supplied by the fuel for a net heat release. In an embodiment, the initial oxygen carrier is CuO, the carrier product is Cu2O, and the oxygen acceptor is Cu.
