Pd-Pb/Al2O3

Pd-Pb/Al₂O₃ Catalyst by B.F.S

Advanced Palladium-Lead Catalyst on Alumina Support for Selective Hydrogenation and Functional Group Tolerance

At B.F.S, we develop high-performance catalysts for complex industrial processes. Our Pd-Pb/Al₂O₃ catalyst combines the hydrogenation activity of palladium (Pd) with the selectivity-enhancing properties of lead (Pb), supported on high-surface-area alumina (Al₂O₃). This catalyst is specifically engineered for selective hydrogenation reactions where precision, functional group tolerance, and suppression of over-hydrogenation are essential.

Key Features

• Selective Hydrogenation Performance
  The addition of lead modifies the electronic environment of palladium, reducing its hydrogenation aggressiveness — ideal for partial hydrogenations.

• Suppression of Over-Hydrogenation
  Especially effective in reactions like alkyne to alkene conversions, where maintaining selectivity is critical.

• Thermally Stable Alumina Support
  γ-Al₂O₃ ensures high surface area, structural integrity, and even metal dispersion for consistent activity.

• Controlled Reactivity
  Ideal for processes requiring hydrogenation near sensitive functional groups (e.g., halides, carbonyls, nitro groups).

• Customizable Formulations
  Typical compositions range from 0.1–1.5 wt% Pd and 0.2–2 wt% Pb, adjusted to suit process requirements.

Applications

Pd-Pb/Al₂O₃ is used in a wide variety of industrial and fine chemical processes, including:

• Partial Hydrogenation of Alkynes
  Conversion of terminal or internal alkynes to alkenes (e.g., phenylacetylene to styrene) with minimal over-reduction.

• Production of Vinyl Compounds
  Including selective acetylene removal from olefin streams.

• Pharmaceutical Intermediates
  Where preserving sensitive functional groups is critical.

• Hydrogenation Under Mild Conditions
  Suitable for batch or continuous operations in gas or liquid phases.
