摘　　要：Cu/SiO2催化剂在硝基苯气相催化加氢生产苯胺中应用,是苯胺生产的关键部分,该Cu基催化剂在使用一段时间后,由于进料状况、积碳以及再生活化过程等因素共同作用,使催化活性下降。本文以某厂100 kt/a苯胺装置为例,介绍南化集团研究院制造的NCH2型Cu/SiO2催化剂在单程寿命结束后的再生和活化过程以及各种可能的因素对该催化剂活性的影响。为进一步优化系统运行提供借鉴和指导。Cu/SiO2 catalyst in gas phase catalytic hydrogenation of nitrobenzene in aniline production application, is a key part of aniline production, catalyst use after period of time, due to the feed condition, carbon deposition and renewable activation process, and other factors, the catalytic activity decline. Taking a factory, aniline device as the example, this paper introduces NCH2 type Cu/SiO2 catalyst regeneration and heating activation process and the factors on catalyst activity, and the influence of catalyst for the further optimization operation, make renewable activation scheme, forecast regeneration time.
