摘　　要：针对榆林甲醇厂60万t/a甲醇装置合成气变换炉原催化剂活性严重衰退导致床层压降过大,进行了催化剂更换。介绍了KC-103S型预硫化耐硫变换催化剂的装填情况及开工导气的过程和应急措施,分析了更换该催化剂后的经济效益。运行结果表明,采用KC-103S型催化剂后,开车过程催化剂无粉碎现象、强度稳定性好,变换炉入口、出口、床层温度未发生明显变化,可缩短开工时间约40 h,经济性良好。With reference to the severe deactivation of the catalyst applied to the synthesis gas shift converter of 600 kt/ a methanol synthesis unit in Yulin Methanol Plant, resulting in too much bed pressure drop, the catalyst was replaced. The loading of the KC- 103S type presulfurization sulfur tolerant shift catalyst, the process of startup gas guiding and its emergency measure were introduced. The economic benefit after the replacement was analyzed. And the operation result showed that the catalyst had no grinding phenomenon in the startup process and the strength stability was good when adopting the KC-103S type catalyst. The inlet,outlet and bed temperature of the shift converter did not change,and the startup time could be shortened by 40 h,with good economic benefit.
