摘　　要：介绍中国石化塔河分公司延长汽油、柴油加氢精制装置精制催化剂RN-10B使用寿命的经验与措施。通过严格监控原料油过滤器的平稳运行、对原料油和脱盐水采用惰性气体保护、监控原料油中非金属和金属无机物含量、优化调整装置氢油比、调整脱后循环氢中H2S含量、合理控制催化剂床层温度、采用合理的催化剂与保护剂组合装填等措施,到2011年6月,加氢精制催化剂RN-10B的运转时间比设计值多501天,单位催化剂处理量比设计值高0.5t/kg。In this paper,some measures to prolong the service life of RN-10B hydrotreating catalyst in the gasoline and diesel fuel hydrotreating unit of SINOPEC Tahe Branch were introduced,such as monitoring the operation of feedstock filter,protecting feedstock and desalted water with inert gas,controlling the content of non-metallic/metallic inorganic compounds in feedstock,optimizing the hydrogen to oil ratio,adopting suitable catalyst and guard catalyst combination,properly adjusting the content of H2S in recycle hydrogen and the temperature of catalyst bed.Since applying these technical measures,till June 2011 the operation period of RN-10B catalyst was 501 d longer than the design value and the processing capacity of per unit catalyst was also higher than the design value（a 0.5 t/kg increase）.
