Abstract: Porous composites of mullite and cordierite are formed by firing an acicular mullite body in the presence of a magnesium source and a silicon source. In some variations of the process, the magnesium and silicon sources are present when the acicular mullite body is formed. In other variations, the magnesium source and the silicon source are applied to a previously-formed acicular mullite body. Surprisingly, the composites have coefficients of linear thermal expansion that are intermediate to those of mullite and cordierite alone, and have higher fracture strengths than cordierite at a similar porosity. Some of the cordierite forms at grain boundaries and/or points of intersection between mullite needles, rather than merely coating the needles. The presence of magnesium and silicon sources during acicular mullite formation does not significantly affect the ability to produce a highly porous network of mullite needles.

Abstract: Nitrogen oxide storage catalysts are used to remove nitrogen oxides from the exhaust gas of internal combustion engines operated predominantly under lean burn conditions. When these catalysts are used in diesel vehicles, the increased sulfur content in the fuel during operation results in poisoning of the catalyst, which is reversible at high temperatures under reduced exhaust gas conditions. In the case of conventional nitrogen oxide storage catalysts, temperatures of more than 600° C. have to be obtained for desulfurization. This is not always possible in diesel vehicles with a nitrogen oxide storage catalyst in the underbody area. The invention presents a process whose application allows the desulfurization temperature of conventional nitrogen oxide storage catalysts which comprise a platinum component and at least one nitrogen oxide storage material to be lowered. The basicity of the chemical environment of the platinum is lowered, while the nitrogen oxide storage material can remain unchanged as such.
