New catalysts from the Institute of Stone Science successfully applied at Takahashi Petrochemicals
Thread Content
To date, the lubricant hydrogenation unit at Takahashi Petrochemical has been operating steadily for over 2 months, using catalysts for lubricant hydrogenation treatment and isomerization dewaxing that were independently developed by the Chinese Academy of Petroleum Sciences. The operation results show that parameters such as the initial temperature at which the catalyst is put into use and the conversion rate are superior to those of imported catalysts, with a significant increase in the yield of heavy lubricating oil. This catalyst utilizes a domestically developed cutting-edge technology, and it exhibits excellent performance in terms of demulsification activity, isomer selectivity, and resistance to poisoning. Compared to previous-generation catalysts, its yield can be increased by more than 12 percentage points; the product has a lower pour point and a higher viscosity index, resulting in significant economic benefits.
