On the other hand, after the reformation the unit specific energy consumption decreased 10 kilogram equal normal fuel oil per ton raw oil. In this paper, author analyse the principle and the advantages of the two stage riser fluidize catalytic cracking technology, where catalyst flow in relay and react in section, and short contact time and high c/o ratio. This paper propose a new method to calculate the catalyst circulation rate in each riser of a two stage riser fluidized catalytic crack unit and find out that the c/o ratio is lower than it should be by calculation use this method and give a suggestion to solve this problem.

本文从理论上分析两段提升管催化裂化技术的催化剂接力、分段反应、短反应时间和大剂油比特点的优越性，并对采用两段提升管技术后装置的生产状况进行核算，还提出了一种适用于两段提升管技术的计算各提升管中催化剂循环量的方法，通过计算分析出装置目前存在的第二提升管剂油比低的问题，并提出了改进建议。
