Spent Hydroprocessing Catalysts

Description

1. Product Overview

Spent Hydroprocessing Catalysts are deactivated catalyst materials recovered from hydroprocessing units such as hydrotreating and hydrocracking operations in petroleum refineries. These catalysts typically contain valuable transition metals deposited on alumina or similar supports and retain recoverable metal content despite operational deactivation. Their primary industrial use is in metal reclamation, catalyst regeneration, and secondary metallurgical processing. The key value proposition lies in enabling cost-efficient recovery of strategic metals while reducing hazardous waste disposal liabilities. Strategically, spent hydroprocessing catalysts represent a critical secondary resource stream in the global refining and metals recycling value chain.

2. Key Specifications & Technical Characteristics

3. Core Industrial Applications

Primary Industries:

• Metal reclamation and recycling companies
• Hydrometallurgical and pyrometallurgical processors
• Catalyst regeneration facilities
• Non-ferrous metal smelters
• Environmental waste treatment operators

Operational Use Cases:

• Recovery of nickel, molybdenum, cobalt, and vanadium through roasting, leaching, or smelting
• Feedstock for secondary metal refining operations
• Catalyst regeneration for limited reuse applications (subject to feasibility)
• Blending input for metallurgical extraction processes

Performance & Cost Advantages:
Spent hydroprocessing catalysts offer a high-value secondary metal source at significantly lower cost than primary mined concentrates. Their concentrated metal content improves extraction efficiency and reduces upstream mining dependency. For metal recovery operators, they provide predictable feedstock chemistry and strong margin potential when integrated into established extraction systems.

4. Competitive Advantages

• Quality Consistency: Batch-level sampling with certified metal assay reporting
• Supply Reliability: Continuous availability from operational refinery hydroprocessing units
• Logistics Capability: Expertise in handling, packaging, and transporting regulated industrial materials
• Price Competitiveness: Attractive pricing relative to primary metal concentrates
• Sustainability Benefits: Supports circular metal recovery and reduces landfill disposal
• Technical Documentation: Assay reports, SDS, and regulatory transport documentation provided

Positioned as a strategic secondary metal resource, Spent Hydroprocessing Catalysts enable buyers to secure cost-effective metal inputs while strengthening sustainability performance and long-term supply resilience.

5. Commercial & Supply Information

• Minimum Order Quantity (MOQ): BULK 20MT
• Loading Capacity (MT per container): Approximately 20–22 MT per 20’ container (subject to packaging format and regulatory classification)
