DEVELOPMENT AND APPLICATION OF PRE-HYDROGENATION CATALYST RS-40 FOR INFERIOR CATALYTIC REFORMING FEEDSTOCK
The hydrotreating catalyst RS-40 for inferior quality catalytic reforming feedstock was successfully developed by SINOPEC Research Institute of Petroleum Processing Co.,Ltd.The results showed that the reaction temperature of catalyst RS-40 could be reduced by about 10 ℃ compared with reference catalyst in the production of qualified reforming feedstock with nitrogen content less than 0.5 μg/g,and exhibited high activity.The catalyst RS-40 had good denitrification activity for naphtha feedstock with high nitrogen content,and the nitrogen mass fraction of the product was less than 0.5 μg/g when processing feedstock with nitrogen mass fraction up to 40 μg/g.In the process of industrial application,catalyst RS-40 also exhibited both high activity and stability.
