摘　　要：针对钴钼系耐硫变换催化剂在使用过程中出现床层温度偏高、活性下降、催化剂积灰等问题,造成转化效率下降进行了原因分析,通过在粗煤气预热器壳程入口管线安装闸阀、更换部分催化剂、增加预变换过滤器等技术手段,有效地解决了变换催化剂使用过程中存在的瓶颈问题,延长了变换催化剂的使用寿命,达到了降本增效。In view of the conversion efficiency decrease due to the problems of Co-Mo sulfur tolerant shift catalyst during the usage,such as high bed temperature,decreased activity,ash accumulation on catalyst,etc.,cause analysis was carried out.Through the technical measures of installing gate valve at the shell side inlet line of crude gas preheater,replacing partial catalyst and adding pre-conversion filter,effectively solved the bottleneck during the usage of shift catalyst,extended its service life,and achieved the goal of cost reduction and efficiency enhancement.
