Diesel Deep Hydrotreating Catalyst
The HHMDS series diesel deep hydrotreating catalyst is a newly developed petrochemical catalytic agent with improved desulfurization activity, and it is also characterized by low bulk density, high dispersity of active metals, reasonable formula of active components, etc.
Application
1. HHMDS-1 Deep Hydrotreating Catalyst
HHMDS-1 is especially designed for the second reforming process of high sulfur diesel, and it delivers satisfying sulfur and olefin removal results, thus providing technical support for oil refineries to manufacture high quality diesel fuels using their 6.0-8.0MPa hydrotreating units at the space velocity of 1.0-2.5h-1. Moreover, the sulfur content of produced diesel oil is compliant with Euro III, Euro IV and Euro V standards.
In general, our W-Mo-Ni hydroprocessing catalyst is a perfect choice for petrochemical industry, and it is commonly adopted in deep hydrotreating process of straight-run diesel, coker diesel, mixture of coker gasoline and coker diesel, etc.
2. HHMDS-2 Deep Hydrotreating Catalyst
HHMDS-2 is aimed at inferior diesel oil with high sulfur and nitrogen contents, and it suits for deep desulfurization, denitrogenation and dearomatization. Compared with other catalysts for second reforming of high-nitrogen distillates, its reaction temperature is about 5℃ lower, and its desulfurization and denitrogenation activities are 20% higher, but their hydrofining results are the same.
This Mo-Ni catalyst is applicable for deep hydrotreating straight-run diesel, coker diesel, mixture of coker gasoline and coker diesel, etc. It also suits for pre-hydrogenation of distillates, such as FCC and hydrocracking materials.
