Description
1. Product Overview
Ni/C Catalyst Residue is a spent nickel-on-carbon hydrogenation catalyst recovered from pharmaceutical, fine chemical, and oleochemical production streams. Its primary industrial use is as a secondary raw material for nickel recovery and recycling by smelters and metal refineries. The key value proposition is high residual nickel content at a significant discount to virgin nickel metal, enabling cost reduction in stainless steel, alloy, and battery precursor supply chains. It is strategically important in the market due to tightening ESG mandates, nickel supply constraints, and the global shift toward circular-economy feedstocks for critical metals.
2. Key Specifications & Technical Characteristics
- Chemical Composition: Nickel (Ni) 15% – 45% on dry basis; Carbon (C) 40% – 80% as support matrix; Moisture 5% – 25%; Trace elements: Fe <2.0%, Al <1.0%, Si <1.5%, S <0.5%
- Purity Level / Grade: Industrial spent catalyst grade; Nickel present as metallic Ni and NiO; Non-hazardous classification subject to SDS verification per batch
- Physical Characteristics: Form: Black to dark grey granular powder or filter cake; Particle Size: 80% passing 100 mesh (150 μm); Bulk Density: 0.6 – 0.9 g/cm³; Magnetic properties due to metallic Ni content
- Packaging Options: 1 MT jumbo bags with inner PE liner on pallets; 25 kg woven PP bags; Bulk direct loading available for 20MT+ orders
- Shelf Life: Stable under dry, covered storage; Recommend processing within 12 months to prevent moisture uptake and agglomeration
3. Core Industrial Applications
- Primary Industries: Non-ferrous metal smelting, stainless steel production, nickel sulfate refining for EV batteries, specialty alloy manufacturing, catalyst regeneration services
- Specific Operational Use Cases: Feedstock for pyrometallurgical or hydrometallurgical nickel recovery; Blending material to adjust nickel units in stainless steel melt shops; Alternative source for nickel salt production after leaching and purification
- Why This Product Performs Better Than Alternatives: Delivers lower cost per contained Ni unit vs. nickel matte or primary cathode; Carbon matrix provides calorific value in smelting, reducing energy input; Existing metallic form improves dissolution kinetics in acid leach circuits vs. laterite ores
