Dealumination - Catalysis

What is Dealumination?

Dealumination is a process used in the field of catalysis to selectively remove aluminum atoms from the framework of aluminosilicate materials, such as zeolites. This modification can significantly alter the physical and chemical properties of the material, enhancing its catalytic performance for various applications.

Why is Dealumination Important in Catalysis?

Dealumination is crucial because it directly influences the acidic properties of the catalyst. By removing aluminum atoms, the number of Brønsted acid sites decreases, while the strength of the remaining acid sites can increase. This change can enhance the selectivity and activity of the catalyst in various reactions, such as cracking, isomerization, and alkylation.

How is Dealumination Achieved?

Dealumination can be achieved through several methods:
