摘　　要：介绍了耐硫变换催化剂QCS - 0 1在德士古水煤浆加压气化制氨装置一段变换炉上的工业应用和 2个生产周期后卸出催化剂的分析测试。应用数据和卸出样的分析测试结果表明 :QCS - 0 1催化剂活性好 ,稳定性高 ,操作弹性大 ,完全能够适用于以水煤浆为原料加压气化大型制氨装置的工艺条件。A description is given of the industrial use of the sulfur tolerant QCS-01 shift catalyst in the primary shift converter of an ammonia unit based on the Texaco process for the gasification under pressure of coal water slurry and the analysis and testing of the catalyst discharged after two production cycles. The data of application and the results from analysis and testing of the discharged sample show that the QCS-01 catalyst is high in activity and flexible in operation, fully adaptable to the process conditions of a large ammonia unit with gasification under pressure of the coal water slurry feedstock. Practice proves that the main cause for the deactivation of the catalyst at the top layer in the primary shift converter is the high content of arsenic in the process gas, leading to poisoning of the catalyst by arsenic.
