National VI diesel production technology passed the appraisal

　　Sinochem News on June 2, the project of "development and application of key technologies for low-cost, low-energy, long-cycle production of China VI diesel" developed by Sinopec Dalian Petrochemical Research Institute and others passed the appraisal of the Ministry of Science and Technology of Sinopec
.

　　The appraisal committee believes that the project has developed a low-cost, high-activity, and stable FHUDS-10 catalyst, which has good activity stability at higher reaction temperatures, and can process a higher proportion of secondary processed diesel.
reach the international leading level
.

　　In response to the multiple demands of hydrogenation units in refining and chemical enterprises, Dalian Institute has carried out key technologies for low-cost, low-energy long-cycle production of National VI diesel, and developed FHUDS-10 diesel ultra-deep hydrodesulfurization catalyst with low cost and good high temperature stability.
The operating cycle of the device is improved, and the adaptability of the device to process different feedstock oils is improved.
The amount of catalyst metal per unit volume is 11.
5% and 17.
2% lower than that of the same type of reference agent at home and abroad, respectively
.

　　At present, the technology has realized industrial application in 9 sets of diesel hydrogenation units such as Jinling Petrochemical and Zhenhai Refinery
.
Among them, the 3 million tons/year diesel hydrogenation unit of Jinling Petrochemical has been running continuously and stably for 17 months, the catalyst activity is stable, and the energy consumption of the unit has been significantly reduced
