预硫化耐硫变换催化剂在煤制合成氨装置的应用

Application of Presulfuration Sulfur Tolerant Shift Catalyst in Synthetic Ammonia Plant Using Coal as Raw Material

预硫化耐硫变换催化剂是催化剂厂家提前硫化的催化剂,具有结构好、稳定性强、强度高、活性好和抗毒性强等特点。煤制合成氨装置的变换系统采用预硫化耐硫变换催化剂不仅可以节约开车时间,减少工艺气放空损失,而且可以消除硫化时安全和环保风险。通过半年的运行,预硫化变换催化剂和传统耐硫变换催化剂工艺稳定性一致。预硫化耐硫变换催化剂在煤制合成氨装置中应用成功。

The presulfuration sulfiar tolerant shift catalyst is a kind of shift catalyst for pre vulcanization ,which has the advantages of good structure,strong stability,high strength,good activity and strong anti toxicity.If the shift system of synthetic ammonia plant using coal as raw material adops presulfuration sulfiar tolerant shift catalyst.The utility model not only saves the driving time,reduces the loss of the process gas,but also can eliminate the risk of safety and environmental protection during vulcanization.The pre sulfurization catalyst and the traditional sulfur tolerant shift catalyst have the same process stability,through the operation of six months.The presulfuration sulfur tolerant shift catalyst is applicated of sucessfully in synthetic ammonia plant using coal as raw material.
