摘要： The invention relates to a method for the selective catalytic reduction of nitrogen oxides using ammonia in exhaust gases of vehicles, whereby solutions of guanidine salts with an ammonia forming potential of between 40 and 850 g/kg, optionally in combination with urea and/or ammonia and/or ammonium salts, are catalytically decomposed in the presence of catalytically active, non-oxidation-active coatings of oxides selected from the group containing titanium dioxide, aluminum oxide, silicon dioxide or the mixtures thereof, and hydrothermally stable zeolites which are fully or partially metal-exchanged. The guanidine salts according to the invention enable a reduction of the nitrogen oxides by approximately 90%. Furthermore, said guanidine salts can enable an increase in the ammonia forming potential from 0.2 kg, corresponding to prior art, up to 0.4 kg ammonia per litre of guanidine salt, along with freezing resistance (freezing point below −25° C.). The risk of corrosion of the guanidine salt solutions used according to the invention is also significantly reduced compared to that of solutions containing ammonium formiate.

摘要： A method for reducing the particle and nitrogen oxide proportion in an exhaust gas flow of an internal combustion engine includes supplying a reducing agent to the exhaust gas flow, subjecting the exhaust gas flow containing the reducing agent to particle filtering, and then carrying out a selective catalytic reduction of at least a portion of the nitrogen oxides in the exhaust gas flow. The method and an exhaust gas treatment unit make it possible to simultaneously reduce the proportion of particles and nitrogen oxides in the exhaust gas. Ammonia, in particular, is used as the reducing agent. Regeneration of the particle filter is promoted by leading an ammonia-containing flow of gas through the particle filter. The method and device make it possible to consume less fuel with the same reaction rate and, at the same time to reduce available installation space, in comparison with existing corresponding prior art systems.

摘要： A device for producing ammonia from urea pellets includes a pellet dispensing device, a pellet accelerator, a pellet shooting channel, and an ammonia reactor having a chamber or zone for shooting in urea pellets and a pellet deflector arranged on an end of the shooting path. The device further includes a urea pellet evaporation device and a hydrolytic catalytic converter. The urea pellets are removed from the reservoir in a regulated number/quantity by a dispensing device and transported to the accelerating device, where the pellets are moved from the pellet shooting channel into the ammonia reactor, where they are broken down into small pieces by impacting a pellet deflector at the end of the shooting path. The pieces are converted into a gas mixture containing ammonia and isocyanic acid by means of a urea evaporation device. The isocyanic acid is subsequently converted into ammonia and carbon dioxide.

摘要： The invention relates to a sorption catalytic converter for the combined chemo-sorptive and oxidative cleaning of diesel engine exhaust gases with a high blocking activity for highly volatile organic exhaust gas components, compounds sorbed on particles, moderately and scarcely volatile organic compounds (SOF), materials with a pungent odor, irritating materials, and ammonia, using an upstream NO.sub.x reducing catalytic converter, with measurable blocking activity for minute high carbon particles, with a high oxidation activity for CO and a restricted oxidation activity for NO and SO.sub.2 with a working range from the ambient temperature to 650.degree. C., comprising a monolithic honeycomb structure having channels adapted for free flow of diesel exhaust gas therethrough of the active mass or of inert carrier material, coated with the active mass, the active mass preferably being composed of V.sub.2 O.sub.5 /WO.sub.3 /MoO.sub.3 mixed oxides borne on sulfatized titanium dioxide, same being doped with platinum metal oxides at a concentration very low in comparison with oxidation catalytic converters, for increasing sorption and oxidation activity. The active mass is employed with 250-1400 g/1 coating composition, whereas for oxidation catalytic converters 50-200 g/1 of coating composition is typical. The significant inhibition of oxidation activity as compared with SO.sub.2 and NO results from a dilution effect (low level of platinum metal; high active mass) and a possible multi-layer structure with a platinum-free or platinum-depleted covering layer. The enhancement of the sorption and oxidation activity is rendered possible by the employment of covering layers with a high pore volume on a honeycomb structure consisting of an active mass whose pore volume is moderately high for reasons of mechanical strength.
