Palladium‑Rh Catalyst Powder

Description

1. Product Overview

This Palladium‑Rh Catalyst Powder is a bimetallic noble metal catalyst engineered for heterogeneous catalytic processes requiring exceptional selectivity and turnover frequency. It is primarily used in hydrogenation, dehydrogenation, and oxidation reactions within continuous and batch industrial reactors. The key value proposition is its optimized Pd:Rh ratio, which enhances catalytic lifetime and resistance to poisons such as sulfur and carbon monoxide. Strategically, it addresses the market need for higher-yield, lower-metal-loading catalysts amid volatile precious metal prices.

2. Key Specifications & Technical Characteristics

• Chemical composition: Bimetallic Pd‑Rh on high‑surface‑area activated carbon or alumina support (custom ratios available: e.g., 5% Pd / 0.5% Rh)

• Purity level: ≥99.95% noble metal basis; total impurities <500 ppm

• Physical characteristics: Fine black powder; D90 particle size: 15–35 µm; surface area: 800–1,200 m²/g (support-dependent); tapped density: 0.4–0.7 g/cm³

• Packaging options: Sealed aluminum foil bags (1 kg, 5 kg), HDPE drums with inert gas purge (10–50 kg), or custom bulk containers with moisture barrier

• Shelf life: 24 months when stored in original sealed packaging under cool, dry, non‑acidic conditions

3. Core Industrial Applications

• Pharmaceutical & API manufacturing: Hydrogenation of nitroaromatics, alkenes, and carbonyl groups – outperforms monometallic Pd with reduced byproduct formation and higher chiral purity.

• Petrochemical & refinery: Selective hydrogenation of acetylenes and dienes in olefin streams – resists coking and sulfur poisoning 3× longer than standard Pd catalysts.

• Fine & specialty chemicals: Debenzylation, reductive amination, and Heck coupling reactions – enables lower catalyst loading (0.1–0.5 mol%) while maintaining >99% conversion.

• Cost advantage: The Rh component suppresses Pd leaching, extending batch cycle life by up to 40% and reducing replacement frequency.

4. Competitive Advantages

• Quality consistency: Every batch is certified by ICP‑OES, BET, and TEM analysis; coefficient of variation <3% across active metal distribution.

• Supply reliability: Backed by multiple geo‑diversified refining partners and a 500+ kg strategic inventory of precursor metals.

• Logistics capability: DDP shipping available to 45+ countries via temperature‑controlled hazardous material logistics partners.

• Price competitiveness: Direct sourcing from primary refineries removes trader margin – formula-based monthly pricing with metal price pass‑through.

• Sustainability: Recoverable and re‑refinable with a take‑back program offering up to 85% residual value credit.

• Technical support: Dedicated catalyst engineers provide reactor loading protocols, regeneration cycles, and spent catalyst assay.

5. Commercial & Supply Information

• Minimum order quantity (MOQ): 1 kg (trial batch) / 25 kg (standard industrial order)

• Bulk 20MT loading capacity: Not applicable – product density limits to ~12 MT per 20-ft container (filled drums, palletized) due to packing material and hazardous goods segregation.

• Note for bulk buyers: Full container loads (FCL) up to 10 metric tons net catalyst powder can be configured with mixed packaging; contact supply chain team for >5 MT orders.
