摘要：
The invention relates to a catalytically active material for reacting nitrogen oxides with ammonia in the presence of hydrocarbons. The material consists of an inner core (1) made of a zeolite exchanged with one or more transition metals or a zeolite-like compound exchanged with one or more transition metals. The core of the catalytically active material is encased by a shell (2), which is made of one or more oxides selected from silicon dioxide, germanium dioxide, aluminum oxide, titanium oxide, tin oxide, cerium oxide, zirconium dioxide, and mixed oxides thereof.
摘要（中）：
它描述了在碳氢化合物存在下氮氧化物与氨反应的催化活性材料。 该材料由与一种或多种过渡金属交换的沸石的内核（1）或与一种或多种过渡金属交换的沸石状化合物组成。 催化活性材料的核心被由选自二氧化硅，二氧化锗，氧化铝，二氧化钛，氧化锡，二氧化铈，氧化锆及其混合氧化物中的一种或多种氧化物形成的壳（2）包封。
