CO adsorbent as well as preparation method and application thereof

The invention discloses a CO adsorbent as well as a preparation method and application thereof. The adsorbent contains basic copper chloride and copper oxide. A cupric chloride hydroxide is synthesized on the surface of a molecular sieve in situ by using a cupric compound and an alkali solution and is used as a precursor to prepare the CO adsorbent. The technical scheme is simple in process operation. The prepared adsorbent does not need to be activated or the activation time is remarkably shortened when the adsorbent is used, and the CO adsorption capacity and selectivity can be effectively improved. 本发明公开了一种CO吸附剂及其制备方法和应用。本发明吸附剂含有碱式氯化铜和氧化铜。利用二价铜化合物与碱溶液在分子筛表面原位合成出碱式氯化铜为前驱体制备CO吸附剂。该技术方案过程操作简单。所制备吸附剂在使用时无需活化或显著缩短活化时间，并能够有效提高CO吸附容量和选择性。
