Magnesium Oxide (MgO) – Enhances thermal stability

Magnesium Oxide (MgO) – Enhancing Thermal Stability in Catalysts

At B.F.S, we supply high-purity Magnesium Oxide (MgO) as a critical additive and support material in advanced catalytic systems. MgO plays a vital role in improving thermal stability, basicity, and mechanical strength of catalysts used in high-temperature industrial processes.

🔬 Why MgO in Catalysis?

Magnesium Oxide is a high-melting-point alkaline earth oxide with a unique combination of properties that make it valuable in various catalyst formulations, especially for reactions conducted above 500°C.

🔍 Key Functions of MgO in Catalytic Systems

Function	Impact
Thermal Stabilization	Prevents sintering of active metal particles at elevated temperatures
Support or Promoter	Enhances dispersion and interaction of active sites
Basic Surface	Promotes reactions involving acidic reactants (e.g., CO₂ adsorption)
Mechanical Durability	Increases pellet hardness and attrition resistance
Coke Resistance	Reduces carbon formation in dehydrogenation and reforming reactions

⚗️ Typical Applications

MgO is used in the formulation of catalysts for:

Steam reforming (as a co-support with Ni)
Dehydrogenation of alkanes
Methanol-to-gasoline (MTG)
Catalytic cracking
Transesterification (for biodiesel synthesis)
CO₂ capture and reforming

🧪 Product Grades from B.F.S

Grade	Surface Area (m²/g)	Particle Size	Applications
BFS-MgO-HS	100+	Fine powder	Catalyst support, CO₂ adsorption
BFS-MgO-Micro	40–80	Micronized	Ni-based reforming catalysts
BFS-MgO-Industrial	10–30	Pelletized	Cracking and high-load reactor systems

All MgO products are calcined, low in impurities, and available in powder or shaped form (extrudates, pellets).

🏭 Performance in High-Temperature Systems

Magnesium Oxide stabilizes metal particles (like Ni, Cu, or Fe) during prolonged high-temperature exposure by:

Suppressing migration and sintering
Creating solid solutions with other oxides
Supporting strong metal-support interactions (SMSI)

🌱 Environmentally Relevant Uses

MgO is also used in:

CO₂ capture technologies
Desulfurization
Waste gas treatment
Catalysts for plastic recycling

Its high alkalinity enables neutralization and stabilization of acidic emissions or feedstocks.
