摘要： The present invention relates to sulfur tolerant catalyst composites useful for reducing contaminants in exhaust gas streams, especially gaseous streams containing sulfur oxide contaminants. More specifically, the present invention is concerned with improved NOx trap catalysts for use in diesel engines as well as lean burn gasoline engines. The sulfur tolerant NOx trap catalyst composites comprise a platinum component, a support, and a NOx sorbent component prepared by hydrothermal synthesis. The NOx sorbent component comprises a first metal oxide and a second metal oxide. The metal in the first metal oxide is selected from the group consisting of aluminum, titanium, zirconium, silicon, and composites thereof, and the metal in the second metal oxide is selected from the group consisting of Group IIA metals, Group II metals, Group IV metals, rare earth metals, and transition metals. The metal in the first metal oxide is different from the metal in the second metal oxide. The sulfur tolerant NOx trap catalyst composites are highly effective with a sulfur containing fuel by trapping sulfur oxide contaminants which tend to poison conventional NOx trap catalysts. The sulfur tolerant NOx trap catalyst composites are particularly suitable for diesel engines because the composites can be regenerated at moderate temperatures with rich pulses, rather than at high temperatures.
摘要翻译：本发明涉及可用于减少废气流中的污染物，特别是含有硫氧化物污染物的气流的耐硫催化剂复合材料。更具体地，本发明涉及用于柴油发动机以及贫燃汽油发动机的改进的NOx捕集催化剂。耐硫NOx捕集催化剂复合材料包括铂组分，载体和通过水热合成制备的NOx吸附剂组分。 NOx吸附剂组分包括第一金属氧化物和第二金属氧化物。第一金属氧化物中的金属选自铝，钛，锆，硅及其复合物，第二金属氧化物中的金属选自第IIA族金属，第II族金属，第 IV金属，稀土金属和过渡金属。第一金属氧化物中的金属不同于第二金属氧化物中的金属。耐硫NOx捕集催化剂复合材料通过捕集易于毒化常规NOx捕集催化剂的硫氧化物污染物，对含硫燃料是非常有效的。耐硫NOx捕集催化剂复合材料特别适用于柴油发动机，因为复合材料可以在中等温度下以丰富的脉冲而不是高温再生。
