摘　　要：对于无取热设施的重油催化裂化装置,反应进料温度对反—再系统热平衡有一定的调节作用,但是靠降低反应进料温度来维持反—再系统热平衡有一定的局限。由于雾化效果变差和剂油比增加导致焦炭产率增加,烧焦放热将会超过由反应进料温度降低而少带入反应器的热量,因此降低反应进料温度有一极限,超过该值对热平衡的调节作用就会发生逆转。Regarding RFCC Unit without heat exchange facility, reducing reaction feeding temperature to keep the system heating balance is a certain limitation. Because atomization effect becomes worse and solvent oil ratio increases, the coke generation ratio increases. Heating released by coke - burning will be more than the heating loss to Reactor because of reaction feeding temperature decrease, so there is a limitation for reducing reaction feeding temperature, and if this heating balance adjustment limitation is exceeded, this function will become reverse.
