摘　　要：结合洛阳石化工程公司新型的ROCC -V重油催化裂化试验装置 ,对影响两器两段再生的几个主要因素进行了分析和探讨 ,结果表明 :一再温度控制在 6 90℃左右、一再烧焦分率控制在 80 %附近 ,对整个再生系统的再生过程是有利的。The paper analyses and discusses several main factors affecting two-regenerator and two-stage regeneration combining with the fluid catalytic cracking of heavy oil of late -model ROCC-V of Luoyang Petrochemical Engineering Corp. The result shows that it is advantage for whole regenerate system to choose the temperature about 690 ℃ and char ratio about 80 % of the first-stage regenerator. At the same time, the relationship of the char amount of second-stage and the difference in temperature of the first-stage and the second-stage regenerator can be found out by calculation.
