摘　　要：通过对流化催化裂化再生器烧焦的几种评价方法进行分析,探讨了采用“烧焦效率“(烧焦效率=按实际操作工况计算的实际烧焦强度÷按合适动力学模型计算的动力学计算烧焦强度)作为评价再生器床层烧焦的合理性,提出了一种评价再生器床层烧焦的新方法。对三套催化裂化装置再生器改造前后实际烧焦强度、动力学计算烧焦强度、烧焦效率的变化进行的分析表明,采用烧焦效率数据可以较好地评价床层再生器的烧焦情况,,指导再生器的设计、操作或改造。A new technique is proposed to evaluate the coke burning in FCC regenerator on the basis of coke burning efficiency （coke burning efficiency = calculated coke burning rate in operation/kinetic coke burning rate calculated by appropriate kinetic model）. The analysis of actual coke burning rates, kinetically calculated coke burning rates and variations of coke burning efficiency of three FCC units before and after revamp indicate that the coke burning efficiency is the important data to evaluate coke burning inside the regenerator and provide guidelines in regenerator design, operation or revamo.
