催化裂化装置中的反应-再生器内部由不同结构和材料的衬里组成，经过长期的使用，衬里不可避免地会出现破损、鼓包和脱落等现象，其中部分特殊部位的修复需采用特殊结构，才能延长其使用周期。简述了衬里的结构及特点，对特殊部位，如龟甲网拼接处、不同类型衬里拼接处、器壁锥段以及设备连接的 Y 型管段处的衬里修复进行了介绍。修复后的衬里使用周期超过3 a，正常生产期间设备外壁温度可控制在规范要求范围内，装置停工期间进行设备内部检查，所修复部位基本完好。

Internal in fluid catalytic cracking reaction regenerator by different structure and ma-terial composition of the lining,the long-term use,the liner will inevitably appear damaged, blistering and shedding,the repair parts of special parts of the need to adopt special structure in order to prolong the service period.The structure characteristics of lining,for the special parts, such as the lining repair hex steel splicing at the different types of stitching,lining,wall cone are described and equipment connected Y type pipe are introduced.After repair of the lining,its service period exceeded for more than 3 years,the outer wall temperature during normal produc-tion equipment could be controlled by standard device,after inspection was made during shut-down,the internal equipment,and repaired parts are basically intact.
