Pd-Ag/Al2O3

Pd-Ag/Al₂O₃ Catalyst by B.F.S

Bimetallic Palladium-Silver Catalyst on Alumina for Enhanced Hydrogenation Efficiency

At B.F.S, we provide cutting-edge catalyst technologies designed to meet the demanding needs of modern chemical and petrochemical industries. Our Pd-Ag/Al₂O₃ catalyst — a bimetallic system of palladium (Pd) and silver (Ag) supported on high-surface-area alumina (Al₂O₃) — offers superior selectivity, thermal stability, and resistance to deactivation for a range of selective hydrogenation applications.

Catalyst Advantages

• Bimetallic Performance
  The synergy between Pd and Ag enhances the catalyst’s selectivity by moderating the activity of palladium, thus reducing over-hydrogenation and improving product purity.

• Stable Alumina Support
  High-purity γ-Al₂O₃ ensures thermal stability, resistance to attrition, and a large surface area for optimal metal dispersion.

• High Selectivity & Activity
  Ideal for processes where controlling hydrogen uptake is crucial — especially in acetylene or diene hydrogenation within ethylene-rich streams.

• Reduced Coking and Deactivation
  Silver addition helps prevent carbon deposition and increases catalyst lifespan.

• Custom Formulations Available
  Pd and Ag loadings can be tailored to meet specific process needs — typically ranging from 0.1 to 1.5 wt% Pd and 0.1 to 0.5 wt% Ag.

Main Applications

Pd-Ag/Al₂O₃ is particularly well-suited for:

• Selective Acetylene Hydrogenation
  In front-end or tail-end ethylene purification units.

• Diene and Alkyne Removal
  In olefin and styrene production streams.

• Hydrogenation of Unsaturated Compounds
  Including nitriles, aldehydes, and conjugated systems in fine chemical synthesis.

• Purification of Feedstocks
  In polymer, fuel, and gas processing plants.
