Introduction
Modern chemical industries rely heavily on catalysts to speed up reactions, improve yield, and reduce energy consumption. In many advanced industrial processes, catalyst carriers (supports) play an equally important role in ensuring catalyst stability and efficiency.
Magnesium Chloride (MgCl₂) is widely used in the chemical and petrochemical industries as a catalyst support material and reaction medium component, especially in polymerization and high-performance chemical reactions. This blog explains how MgCl₂ is used in catalyst systems and industrial reactions.
What Are Catalyst Carriers?
Catalyst carriers (or supports) are materials that:
- Hold and stabilize active catalytic substances
- Increase surface area for reactions
- Improve catalyst efficiency and lifespan
- Control reaction behavior
Common catalyst carriers include silica, alumina, and magnesium-based compounds.
Why MgCl₂ is Used in Catalyst Systems
Magnesium Chloride is widely used because it:
- Has strong chemical stability
- Provides a high surface area when modified
- Enhances dispersion of active catalyst components
- Works well in polymerization systems
