摘　　要：在煤化工大规模产业化的新形势下,水煤气变换装置的稳定、可靠、经济运行尤为重要,而开展变换催化剂全生命周期管理是保证变换装置安稳长满优运行的有效手段。以某180万t/a煤制甲醇项目变换装置预硫化钴钼系变换催化剂为例,对其在装填、日常操作、开停车处理和运行末期特护各阶段开展研究和工况优化,做出针对性地诊断分析和调整,减缓催化剂活性衰减,将其使用寿命由26280 h延长至30000 h。Under the new situation of large-scale industrialization of coal chemical industry,the problem of stability,reliability and economy of water gas conversion unit became more and more prominent.The key to solve this problem was to carry out the whole life cycle management of conversion catalyst.Taking pre-sulfation Co-Mo conversion catalyst in the conversion unit of a 1.8 million t/a coal-to-methanol plant as an example,the research and working condition optimization were carried out in the various stages of catalyst loading,daily operation,start-up and shutdown treatment and special maintenance at the end of catalyst operation,and pertinent diagnosis,analysis and adjustment were made to reduce the attenuation of catalyst activity,extending its service life from 26,280 h to 30,000 h.
