- Description:Selective hydrogenation - C5+ cuts liquid phase hydrogenation
- Characteristics:Ni, Al2O3
LD 341 is the catalyst of choice if sweetening (reduction of mercaptans content) is needed.
LD 341 is a nickel-on-alumina catalyst used for the selective hydrogenation of diolefins present in pyrolysis gasoline.
It is used in the first step hydrogenation and can be associated with a CoMo catalyst placed in a second step reactor for aromatics production after olefins hydrogenation and hydro desulfurization.
