被动NOX吸附剂
摘要：
公开了一种被动NOx吸附剂。该被动NOx吸附剂有效地在或低于低温吸附NOx，并在高于该低温的温度释放吸附的NOx。该被动NOx吸附剂包含贵金属和具有LTL骨架类型的分子筛。本发明还包括包含该被动NOx吸附剂的排气系统，和利用该被动NOx吸附剂处理内燃机废气的方法。
摘要（英）：

A passive NOx adsorber is disclosed. The passive NOx adsorber is effective to adsorb NOx at or below a low temperature and release the adsorbed NOx at temperatures above the low temperature. The passive NOx adsorber comprises a noble metal and a molecular sieve having an LTL Framework Type. The invention also includes an exhaust system comprising the passive NOx adsorber, and a method for treatingexhaust gas from an internal combustion engine utilizing the passive NOx adsorber.
