Representative Case Study 07 — Refineries & Petrochemicals
Non-Acidic Petroleum Catalyst Regeneration & Rejuvenation
Selecting a technically appropriate regeneration route on the basis of catalyst characterization.
Challenge
During operation, refining catalysts may suffer from:
Coke DepositionCarbon FoulingSulfur PoisoningMetal DepositionPore BlockingSinteringLoss of Active Surface

Analytical Framework
- Surface Area
- Pore Volume
- Pore Distribution
- Coke Content
- Sulfur
- Nickel
- Vanadium
- Active Metal Dispersion
- Catalyst Activity
- Mechanical Strength
Possible Non-Acidic Routes
Depending on catalyst type and deactivation mechanism:
- Controlled Thermal Treatment
- Controlled Oxidative Regeneration
- Steam-Assisted Treatment
- Hydrogen-Assisted Treatment
- Solvent-Based Cleaning
- Controlled Redox Treatment
- Rejuvenation / Re-dispersion Strategies
No single regeneration method is universally applicable to all refinery catalysts. IGT evaluates the catalyst, deactivation mechanism and process history before selecting a technically appropriate regeneration or rejuvenation route.
