What Catalysts Are Used in the Partial Oxidation of Methane?
The partial oxidation of methane (POM) is a crucial chemical process used to produce syngas, a mixture of carbon monoxide (CO) and hydrogen (H₂). This syngas serves as a foundational feedstock in the production of ammonia, methanol, and synthetic fuels. But at the heart of this transformation lies a critical factor: the catalyst.
Why Catalysts Matter in POM
Catalysts not only improve methane conversion rates but also control selectivity, reduce unwanted byproducts, and optimize thermal efficiency. The right catalyst enables higher syngas yields at lower energy costs making it essential for industries aiming for cleaner and more efficient processing.
Common Catalysts for Methane Partial Oxidation
1. Nickel-Based Catalysts
Nickel supported on materials like Al₂O₃, CeO₂, or ZrO₂ is widely used due to its affordability and strong performance. These catalysts facilitate high CH₄ conversion under moderate temperatures and are often applied in combustion-reforming hybrid processes.
2. Dual-Metal Alloys (e.g., Mo–Ni)
Recent innovations have introduced atomically dispersed dual-metal alloys like Mo–Ni, which demonstrate excellent oxygen activation and methane dissociation properties. These catalysts offer: 95% methane conversion
- ~97% syngas selectivity
- High thermal stability
3. Noble Metal Catalysts
Catalysts such as rhodium (Rh), palladium (Pd), and platinum (Pt) are more expensive but offer enhanced selectivity and durability, especially when supported on zeolites or ceria-based oxides. These are especially suitable for low-temperature POM and small-scale applications.
