PS-Ⅶ型连续重整催化剂的工业应用

石油化工科学研究院开发的PS-Ⅶ连续重整催化剂在扬子石油化工股份有限公司1.39Mt/a装置上进行了首次工业应用。工业运转结果和标定结果均表明，PS-Ⅶ型连续重整催化剂具有良好的耐磨性能和比表面积稳定性；与原使用催化剂相比，在原料芳潜较低的情况下，PS-Ⅶ型催化剂的C6+以上收率提高了3.32个百分点，氢气产率增加了0.61个百分点，芳烃产率增加了1.53个百分点，积炭速率降低了27.32％，解决了重整装置扩能后再生能力受限制的问题，使重整装置得以保持长期高负荷运转。

COMMERCIAL APPLICATION OF PS-Ⅶ CATALYST FOR CONTINUOUS CATALYST REGENERATION REFORMING UNIT

The first commercial application of PS-VII catalyst developed by Research Institute of Petroleum Processing was carried out in the 1.39Mt/a continuous catalyst regeneration (CCR) reforming unit of Yangzi Petrochemical Company. The results of performance test and commercial run showed that PS-VII catalyst exhibited high attrition resistant and good hydrothermal stability. As compared with the original imported catalyst, using PS-VII catalyst even with a poorer feedstock, the yields of C6+, hydrogen and aromatics increased 3.32, 0.61 and 1.53 percentage points, respectively; at the same time the coke deposition rate reduced 27.32%. Thus, the problem of insufficient regeneration capacity was solved and the unit could be run under high load for a long period.
