| 摘 要： | 在热重分析仪上进行结焦失活的Fe-ZSM-5分子筛积炭催化剂再生烧炭实验，考察再生温度、O2浓度、体积空速及再生时间对烧炭过程的影响。结果表明，失活Fe-ZSM-5催化剂较适宜的烧炭工艺条件为烧炭温度550℃、O2体积分数10%～15%，体积空速3000 h 1，烧炭时间60 min。由此得到了再生烧炭的表观动力学方程及其相关的动力学参数。

| Abstract: | The regeneration of coked Fe-ZSM-5 zeolite catalyst was studied in a thermogravimetric apparatus. The effects of regeneration temperature, O2 concentration, gas hour space velocity and regeneration time on the coke-burning process were investigated, respectively. The results showed that the optimum conditions for coke burning of the coked catalyst were the temperature of 550℃, O2 volume fraction of 10%~15%, gas hour space velocity of 3000 h-1 and regeneration time of 60 min. Coke burning kinetic equation and related kinetic parameters in catalyst regeneration were obtained. |
