Catalyst CC-00083 was researched and developed by FRIPP. It is a kind of hydrocracking catalyst possessing strong N-resistant property. Catalyst CC-00083 adopts molecular sieve US-SSY and amorphous Si-Al as cracking components, and adopts W-Ni as hydrogenation components so that it possesses higher activity and higher selectivity of mid-distillate.
The most important characteristic of catalyst CC-00083 is the better N-resistant property. It is able to contain the higher activity and stability under the condition of the content of nitrogen in refining oil lower than 20～50ppm. Even under the condition of the content of nitrogen in refining oil between 80～100ppm, it also can stably run and be used in regeneration. Catalyst CC-00083 was first used in the hydrocracking device of Liaoyang Petrochemical Company in April 1998, and the running result of catalyst CC-00083 in industrial application is fairly good.
