摘要
通过试验,对钙钛矿型复合氧化物催化剂La0.9K0.1CoO3处理NOx和微粒的工作条件进行了研究,结果表明,反应温度、氮氧化物的浓度、氧气的浓度以及催化剂与微粒的接触程度,是影响催化反应进行的主要因素,同时给出了反应条件。该催化剂的反应条件与柴油机尾气状况相近,通过与其他氮氧化物后处理技术协同作用,可望达到较好的去除汽车尾气污染物的效果。
Through experiments, the working condition of diesel waste gas NOx and PM treatment using La0.9K0.1CoO3 perovskite-type oxide is investigated. The results show that the temperature, the contents of NOx, O2 and the contact between the catalyst and dry soot influence the chemical reactions mainly. The reaction conditions are proposed, which are similar to the diesel tail gas condition. The combination with other diesel waste gas cleaning techniques could be performed and thus an excellent waste gas treatment may be obtained.
