延长连续重整催化剂使用寿命的技术措施

TECHNICAL MEASURES FOR EXTENDING THE SERVICELIFE OF THE CONTINUOUS REFORMING CATALYST

为提高扬子石油化工公司芳烃联合装置的整体经济效益，充分发挥催化剂的末期性能，多产芳烃，从原料、重整反应和催化剂再生操作条件进行了优化控制，包括控制重整原料初馏点在８０～８５℃、终馏点≤１６５℃；根据催化剂活性的下降情况提高反应温度；适当降低氢油比；加大注氯量，使再生和待生催化剂的氯含量平均值维持在１．０５％左右；控制系统的水分含量。结果表明，这些措施是切实可行的。

Technical measures were taken to give full play to the final phase performance of the catalyst for increasing the economic effect, which included optimizing feedstock and the operating conditions of both reaction and catalyst regeneration. The initial and end boiling points of the feedstock were controlled in the range of 80 to 85 and less than 165 respectively; raising the reaction temperature in accordance with the decline of catalyst activity; decreasing the hydrogen to oil ratio; increasing the catalyst average chlorine content to around 1.05%; and controlling the water content of the system. These measures extended the service life of the catalyst.
