  • Patent number: 8226914
    Abstract: Soot filters for removing soot from the exhaust gas of lean-burn engines become blocked with progressive operating duration on account of the deposition of soot, and must therefore be regenerated at regular intervals. It has been found that reliable operation of the soot filter is possible only if an active regeneration is carried out from time to time by increasing the exhaust-gas temperature to the soot ignition temperature. For this purpose, an oxidation catalytic converter is usually arranged upstream of the soot filter, and the exhaust-gas temperature is increased by means of the catalytic combustion of additionally injected fuel. Here, the oxidation catalytic converter is subjected to high temperature loading and therefore ages very quickly.

The exhaust gas is directed within the cone. The flow of exhaust gas has an elevated temperature compared to an ambient. A further step includes creating a drag force on the injected reductant to increase travel time of the injected reductant from the injector to the catalyst.

    Abstract: The oxidation of nitrogen oxide (NO) in an oxygen-containing exhaust gas flow from a diesel or other lean-burn engine may be catalyzed using particles of co-precipitated and calcined manganese (Mn), cerium (Ce) and zirconium (Zr) mixed oxides. In preferred embodiments, the molar ratios of Mn, Ce and Zr to the total amount of base metals in the ternary mixed oxide catalyst are in the range of 0.25-0.35, 0.40-0.50 and 0.20-0.25, respectively. Further, this ternary mixed oxide catalyst is less susceptible to sulfur poisoning than previously-disclosed binary mixed oxide catalysts. The ternary mixed oxide catalyst may also be regenerated—and the inhibiting effect of SO2 reversed—by briefly exposing the catalyst to a reducing exhaust gas environment.

  • Patent number: 8101304
    Abstract: The present invention relates to a process for the concentration of noble metals from fluorine-containing components of fuel cells, for example from PEM fuel cell stacks, DMFC fuel cells, catalyst-coated membranes (CCMs), membrane electrode assemblies (MEAs), catalyst pastes, etc. The process is based on an optionally multi-step heat treatment process comprising a combustion and/or a melting process. It allows an inexpensive, simple concentration of noble materials. The hydrogen fluoride formed during the heat treatment of fluorine-containing components is bound by an inorganic additive so that no harmful hydrogen fluoride emissions occur. The process can be used for the recovery of noble metals that are present as components in fuel cells, electrolysis cells, batteries, and the like.
