摘要: The invention proposes a method for the purification of exhaust gases which are generated by a diesel engine with a charging turbine, and a special device for carrying out said method. The device comprises, in the flow direction of the exhaust gas, a dosing device for a reducing agent from a reducing agent reservoir (2), an SCR catalytic converter (3), an oxidation catalytic converter (4) and a diesel particle filter (5). The system is particularly suitable for the purification of the exhaust gases of diesel vehicles in which engines with a turbocharger (charging turbine (1)) and an exhaust-gas recirculation device are used, which engines generate exhaust gases which, in addition to carbon monoxide, hydrocarbons and particles, have nitrogen oxides with an NO2/NOX ratio of between 0.3 and 0.7.

摘要: The invention relates to a method for producing aqueous preparations of complexes of platinum group metals (PGM) Pt, Pd, Rh and Ir having the general formula [MA/MB/MC(L)a(H2O)b(O2—)c(OH−)d](OH—)e(H+)f, wherein MA=PtII or PdII, MB=PtIV, MC=Rh or Ir, L is a neutral monodentate or bidentate donor ligand, and a is an integer between 1 and 4 (or 2) and/or between 1 and 6 (or 3), b is an integer between 0 and 3 (or 5), c is an integer between 0 and 3 (or 4), d is an integer between 0 and 3 (or 5), e is an integer between 0 and 2 (or 3 or 4) and f is an integer between 0 and 4 (or 5). In the method according to the invention, the hydroxo complexes H2Pd(OH)4 (in the case of MA=PdII), H2Pt(OH)6 (in the case of MA=PtII and MB=PtIV) or H3MC(OH)6 (for MC=RhIIIIrIII) are converted in the presence of the donor ligands, wherein at least one hydroxo group of the hydro complex is exchanged. Preferably, the reaction occurs at temperatures in the range of 40 to 110° C. with a reaction time of between 2 and 24 hours, wherein, where MA=PtII, the conversion additionally occurs in the presence of a reduction agent. The method optionally further comprises an exchange of OH anions bound outside of the complex sphere with other anions (e.g. hydrogen carbonate or carbonate anions). The aqueous preparations contain PGM complexes such as [Pt(en)2](OH)2, [Pt(EA)4](OH)2 or [Rh(NH3)6](OH)3 and are used to produce electroplating baths, heterogeneous catalysts or metal powders, for example.

摘要: Weighing device used with piece goods, having a belt conveyor, one or more below positioned scales of rigid arrangement and a support for goods being weighed. The belt conveyor has at least two belts. The support has at least one support extension guidable through between the belts, and the belts can move toward the scale such that support extensions are guided through between the conveyor belts without moving themselves. Goods moved on the belts are laid upon the support extensions and weighed. The conveyor unit above the scale is moveable, in its entirety, towards the weighing scale. Conveyor movement end positions are damped. The conveyor is moved by a single actuator, and at least two weighing scales are used with different weighing regions. A coating installation for car exhaust gas catalyst carriers is provided with the weighing device. A method of weighing piece goods using the weighing device is provided.

摘要: The present invention relates to the use of different regeneration strategies for nitrogen oxide storage catalysts (NOx storage catalyst, LNT or NSC), depending on the exhaust gas temperatures, to reduce in the total exhaust gas the greenhouse gas N2O (nitrous oxide) that is produced as a secondary emission during the regeneration of the storage catalyst. If the exhaust gas temperature is below 275° C.-290° C., regeneration takes place using a strategy with short pulses of around 2 seconds and λ Lambda 0.95 rich.
