- Description: Selective Hydrogenation - C5+ cuts liquid phase hydrogenation
- Characteristics:Pd, Al2O3
- Shape: Spheres
LD 485 is a very active palladium on alumina catalyst specially designed for hydrogenation of pyrolysis gasoline cuts.
Its very open pore structure maximizes the efficiency of active palladium.
This catalyst is of particular choice for feedstock rich in styrene, or when high capacity or high severity is required.
Used in first stage hydrogenation reactor, it stabilizes the py-gas by diolefins selective hydrogenation. This hydrogenated pyrolysis gasoline is suitable for further hydrotreatment on CoMo catalysts, like HR 406.
LD 485 can also be used in total hydrogenation applications of lighter C3, C4 and C5 olefinic cuts.
