摘 要: | 介绍了某公司芳烃生产项目中3.2Mt/a连续催化重整装置催化剂再生技术特点,该装置采用UOP第三代催化剂连续再生Cyclemax专利技术。从催化剂的装填、催化剂循环、ChlorsorbTM氯吸收等方面对装置开工及运行情况进行分析介绍,对开工和运行中遇到的问题:如催化剂提升不畅、系统催化剂粉尘量偏大、氯吸收罐超温、催化剂强度和比表面积下降快等问题,通过磨合、消缺和优化。在采用固相脱氯技术替代ChlorsorbTM氯吸收技术,重整混合进料换热器更换为缠绕管式换热器等措施后,催化剂循环系统流畅,催化剂粉尘量小于10 kg?d-1,在反应器入口温度不高于530℃的工况下,重整反应总温降达316℃,催化剂表现出优良的性能。

CHARACTERISTICS AND OPERATION OF CATALYST REGENERATION TECHNOLOGY IN CONTINUOUS CATALYTIC REFORMING UNIT |

Abstract: | The characteristics of catalyst regeneration technology of a 3.2 Mt/a continuous catalytic reforming unit in the aromatics project, which adopted the UOP patented Cyclemax continuous regeneration technology, were introduced. The start-up and operation of the plant were analyzed in terms of catalyst loading, catalyst circulation and chlorine absorption by ChlorsorbTM. The problems encountered in the start-up and operation, such as poor catalyst lifting, excessive catalyst dust, over-temperature of chlorine absorption tank, rapid decreases of catalyst strength and specific surface area, were described and analyzed. After using solid-phase dechlorination technology to replace the ChlorsorbTM, and adopting the spiral-wound tube heat exchanger for the mixed feed of the unit, the catalyst circulation system was smooth and the catalyst dust content reduced to less than 10 kg/d, the total temperature reduction of reforming reaction dropped to 316 ℃ when the inlet temperature of the reactor was not higher than 530 ℃. The catalyst showed excellent performance. |
