摘要
催化裂化装置原料中的硫大约有 5 %～ 15 %在加工过程中和焦炭一起沉积在催化剂上 ,在催化剂再生过程中以SOx 形式与再生烟气一起排放到空气中而污染环境。工业试验证明HL -9硫转移剂可以减少烟气中SOx的排放量 ,同时该剂具有金属钝化作用 ,对产品分布和产品质量无不良影响。
About 5～15% sulfur in FCCU feedstock is deposited on the surface of the catalyst with coke during the process and is discharged into air in the form of Sox with regenerated fume. Industrial test proves that sulfur transfer agent HL-09 can reduce the discharge of Sox in the fume. Moreover, it has no unfavorable effect on distribution and quality of the product due to its passivation effect.
