摘　　要：利用助剂热洗-离心技术对催化裂化外甩油浆进行脱固处理,考察了反应温度、增重剂、沉降助剂、破乳剂种类及加入量、离心转速等工艺条件对脱固效果的影响。结果表明:在反应温度为70℃,催化裂化油浆/增重助剂(质量比)为10∶3,CS-11型沉降助剂投加质量分数为0.4%,PE-12型破乳剂投加质量分数为0.2%的条件下充分反应后,在离心转速为8 000 r/min时,对催化裂化外甩油浆进行脱固处理后,油浆灰分质量分数由0.390%降至0.041%。The hot washing-centrifugal process of auxiliaries was used to remove solids from fluid catalytic cracking(FCC) slurry,and the effects such as reaction temperature, type and amount of weighting agent, sedimentation agent and demulsifier,centrifugal speed on removing effectiveness were investigated.The results showed that under the optimized operating conditions of reaction temperature 70℃,mass ratio of FCC slurry to weight agent10 ∶3,mass fraction of CS-11 sedimentation agent0.40%,mass fraction of PE-12 demulsifier 0.2%,centrifugal speed 8 000 r/min,the ash mass fraction of FCC slurry would reduced from 0.390% to0.041%.
