Application : Butadiene Hydrogenation with 1-Butene Isomerization
Type : Pre-reduced Pd, Al2O3
Shape : Spheres

LD 269 is a palladium catalyst specially designed to selectively reduce diolefins (i.e. while preserving olefins) and maximize the isomerization of external to internal olefins (double bond shift) High isomerization rate is obtained without loss of total olefins through over hydrogenation to alkane. Due to its high activity, selectivity and tolerance to impurities, LD 269 is of special interest for C4 alkylation pretreatment (Axens Alkyfining Process) or for olefin polymerisation pretreatment.

LD 269 can be delivered in oxide or prereduced form. In the latter case, the hydrogen treatment of the catalyst after loading can be as low as ambient temperature.
