Where is LD 269 used?
- Description: Selective hydrogenation - Butadiene hydrogenation with 1-Butene isomerization
- Characteristics:Pd, Al2O3
LD 269 is a palladium catalyst specially designed to maximize the isomerization of 1-butene to 2-butene while selectively hydrogenating any butadiene present to butenes.
The isomerization is obtained without loss of total olefins through over-hydrogenation to alkanes. LD 269 is of special interest for C4 HF alkylation pretreatment or for olefin polymerization pre-treatment (Axens Alkyfining® Process).
