Abstract: The industrial application of new FCC anti-vanadium catalyst CGP-C(V) in SINOPEC Maoming Petrochemical Company is introduced. New FCC anti-vanadium catalyst is developed by means of the newly developed catalyst particles surface coating technology, which can be used in FCC unit under oxygen enriched regeneration conditions. The catalyst is replaced according to the normal consumption of the unit, the supplement amount of CGP-C(V) is about 3.7 t/d, and the unit consumption of each ton of fresh feedstock is about 1.4 kg/t. After using the new catalyst, when the mass fractions of nickel and vanadium of equilibrium catalyst are both about 7 000 μg/g, the average activity of the equilibrium catalyst increases by 4.8 units, and the specific surface area of the equilibrium catalyst increases by 19 m2/g, which shows that the catalyst has better tolerance of vanadium and excellent activity stability.
