摘要： A sulfur oxide storage material contains a magnesium-aluminum spinel (MgO.Al2O3) and can be used as a so-called “sulfur trap” to remove sulfur oxides from oxygen-containing exhaust gases of industrial processes. In particular, it can be used for the catalytic purification of exhaust gas from internal-combustion engines to remove the sulfur oxides from the exhaust gas in order to protect the exhaust gas catalysts from sulfur poisoning. The material displays a molar ratio of magnesium oxide to aluminum oxide in the range of over 1.1:1, and the magnesium oxide present in stoichiometric excess is homogeneously distributed in a highly disperse form in the storage material.

摘要： A nitrogen oxide storage catalyst which contains at least one catalyst material and at least one nitrogen oxide storage component from the group of alkali and alkaline earth metals. The nitrogen oxide storage component, after completing catalyst preparation, is present as finely divided barium sulfate, strontium sulfate, a mixture or mixed crystals of the two sulfates, or as their complete or incomplete decomposition product with an average particle size of less than 1 &mgr;m. Barium sulfate and/or strontium sulfate act as feed materials for the active storage component in the storage catalyst according to the invention. As a result of the reductive exhaust gas compositions occurring under normal automobile driving conditions barium sulfate and strontium sulfate decompose to compounds which are able to store nitrogen oxides. This compensates for the loss of active storage components which occurs due to aging. Barium sulfate and/or strontium sulfate may be decomposed during production by means of reductive calcination in order to obtain a high initial loading of the catalyst with storage compounds. In this case, these sulfates are used as auxiliary agents in order to introduce the highest possible concentrations of storage compounds into the storage catalyst.

摘要： The present invention provides processes for checking the operability of a nitrogen oxide storage catalyst during operation of a lean burn engine. The processes of the present invention utilize a nitrogen oxide storage material, a catalytically active component and optionally an oxygen storage material. During lean burn engine operation, damage to the catalytically active components is detected if the nitrogen oxide storage capacity in the kinetically controlled temperature range is lowered and damage to the storage material is detected if the nitrogen oxide storage capacity is lowered in the thermodynamically controlled temperature range.

摘要： A process for evaluating performance deterioration of a nitrogen oxide storage catalyst which has a nitrogen oxide storage function and an oxygen storage function and is operated with cyclic alternation of the air/fuel ratio in the exhaust gas from lean to rich. The nitrogen oxides are stored during the lean phase and the nitrogen oxides are desorbed and converted during the rich phase. To check the serviceability of the storage catalyst, the air/fuel ratio of the exhaust gas is switched from lean to rich and the rich phase is extended beyond the time required for complete desorption of the nitrogen oxides until at least the rich exhaust gas passes right through the catalyst and the time interval &Dgr;t1 produced between the first change-over until breakthrough of the rich exhaust gas and, after again switching from rich to lean running, the time interval &Dgr;t2 produced between the second change-over and passage of oxygen through the catalyst are measured and the time differences &Dgr;t1 and &Dgr;t2 are used for separate assessment of the oxygen storage function and the nitrogen oxide storage function of the catalyst.

The method is carried out by suspending the support material in an aqueous solution of precursors of the storage components, this suspension is then introduced into a hot gas stream, the temperature of which is calculated so that, during a residence time of the suspension in the hot gas stream of less than one minute, the solvent of the suspension is evaporated out and the precursors of the storage components are thermally broken down and converted to the storage components before the storage material that forms in this way is separated from the stream of hot gases.
