Highly selective for diene hydrogenation, minimizing over-hydrogenation to saturated alkanes.
Thermally stable under industrial fixed-bed and slurry-phase reactor conditions.
Low palladium loading enables cost-efficient operation without compromising activity.
Engineered for excellent resistance to sulfur and nitrogen-containing impurities in feedstocks.
Consistent batch-to-batch performance validated through Clariant’s ISO 9001-certified manufacturing.
Selective hydrogenation of C4–C8 diolefins in petrochemical naphtha and cracked gasoline streams.
Purification of butadiene feedstock for synthetic rubber production (e.g., SBR, BR).
Removal of residual dienes from polymer-grade isoprene and piperylene.
Upgrading of bio-derived hydrocarbon intermediates containing conjugated diene impurities.
Refining of specialty solvents requiring ultra-low diene content (<1 ppm).
