MCM-22 Molecular Sieve

Product Overview
MCM-22 is a molecular sieve with a unique dual-channel structure, consisting of two distinct, non-interconnected pore systems. The intralayer pores are 0.40×0.59nm 10-membered ring two-dimensional sinusoidal channels, while the interlayer pores are 0.71×0.82nm 12-membered ring supercages that open to the exterior. This exceptional pore structure gives MCM-22 outstanding catalytic properties, especially for reactions such as alkylation, isomerization, disproportionation, and catalytic cracking in gasoline reforming. Its high surface area and unique pore system provide excellent performance in a wide range of catalytic applications.

Key Features

• Unique Dual-Pore Structure: The combination of 10-membered ring intralayer pores and 12-membered ring interlayer supercages enhances the catalytic activity and selectivity of the sieve.
• High Catalytic Activity: Exhibits excellent catalytic performance in reactions such as alkylation, isomerization, and disproportionation of aromatics.
• Good Stability: Demonstrates strong thermal and chemical stability, making it suitable for a wide range of catalytic processes under varying conditions.
• Exceptional Selectivity: Highly selective for different molecules, particularly effective in catalytic cracking and isomerization reactions in gasoline reforming.

Applications

• Aromatic Alkylation: Used in the alkylation of aromatics, widely applied in petrochemical and synthetic chemical production.
• Aromatic Isomerization and Disproportionation: Suitable for isomerization and disproportionation of aromatics, improving the quality and yield of the products.
• Gasoline Reforming Catalytic Cracking: Applied in gasoline reforming catalytic cracking processes to enhance the quality of olefin products and improve selectivity.
• Petrochemical Industry: Used in petroleum refining and hydrocarbon conversion reactions, increasing reaction rates and selectivity.
