Description
1. Product Overview
Spent Co-Based Refinery Catalyst is a secondary raw material recovered from hydroprocessing units in petroleum refineries after the completion of its primary catalytic cycle. Its principal industrial use is as a high-grade feedstock for cobalt, molybdenum, and nickel recovery, as well as for direct reuse in catalyst manufacturing following regeneration. The key value proposition lies in delivering critical metals at a lower cost and carbon footprint compared to virgin mining, while meeting stringent metallurgical specifications. In today’s market, where supply chain security and ESG compliance drive procurement decisions, this material is strategically important for refiners, smelters, and chemical producers seeking sustainable, cost-effective access to cobalt and associated metals.
2. Key Specifications & Technical Characteristics
- Chemical Composition: Typical metal content Co 2–12% w/w, Mo 4–18% w/w, Ni 0.5–5% w/w, Al 20–35% w/w as Al2O3 support, balance carbon, sulfur, and residual hydrocarbons
- Purity/Grade: Classified as Hazardous Secondary Material; metals recoverable to 98.5%+ via hydrometallurgical processing; low contamination from Si, Fe, V, P
- Physical Characteristics:
- Form: Extrudates, trilobes, or quadralobes; spent powder fines available
- Color: Dark grey to black
- Particle Size: 1.2–3.5 mm diameter for extrudates; <150 micron for fines
- Bulk Density: 0.55–0.85 g/cm³
- Moisture: <3% w/w
- Carbon Content: 3–15% w/w, sulfur 2–10% w/w
- Packaging Options: 1 MT jumbo bags with inner PE liner on heat-treated pallets; 20’ FCL bulk loading; UN-certified drums available for hazmat transport
- Shelf Life: Indefinite when stored dry in sealed packaging; no degradation of metal content under proper conditions
3. Core Industrial Applications
- Primary Industries: Non-ferrous metal refining, specialty chemicals, catalyst manufacturing, battery materials, steel alloying, environmental services
- Specific Operational Use Cases:
- Feedstock for Co/Mo/Ni recovery via roasting, leaching, and solvent extraction
- Regeneration and reuse in hydrodesulfurization and hydrocracking units after carbon/sulfur burn-off
- Precursor for cobalt sulfate and cobalt oxide used in lithium-ion battery cathodes
- Alloying additive in superalloy and tool steel production
- Performance vs. Alternatives: Offers 20–40% cost advantage over virgin cobalt concentrates and reduces dependency on geopolitically sensitive DRC supply chains. Regenerated catalyst maintains >90% of fresh activity, lowering refinery opex. Hydrometallurgical recovery achieves higher metal yields than processing lower-grade laterite ores
- Efficiency/Durability/Cost Advantages: Eliminates mining and beneficiation stages, reducing energy consumption by up to 65%. Provides predictable, assay-certified metal units with traceable origin. Enables circular economy compliance for refineries under tightening waste regulations
