ZSM-5 Molecular Sieve

Product Overview
ZSM-5 molecular sieve is a high-performance silica-alumina zeolite with excellent properties, including high hydrothermal stability, a large surface area, and unique surface acidity. It provides effective shape-selective catalytic properties, making it widely used in the oil refining industry, fine chemicals, environmental protection, and electrochemical applications. Its wide range of silicon-to-aluminum ratios allows it to be adapted to various processes and applications.

Key Features

• High Hydrothermal Stability: Maintains its structure and performance even in high-temperature and high-humidity environments.
• High Surface Area: Offers more active sites, enhancing catalytic efficiency.
• Excellent Shape-Selective Catalytic Effect: Provides high selectivity, improving the efficiency of specific catalytic reactions.
• Wide Range of Silicon-to-Aluminum Ratios: Can be customized for different reaction requirements, optimizing catalytic performance.
• Low Carbon Formation: Extends the catalyst’s lifespan and reduces the need for regular maintenance.
• Unique Surface Acidity: Enhances the sieve’s ability to adsorb and catalyze large molecules.

Applications

• Oil Refining: Used in processes like diesel hydrodewaxing, lubricating oil catalytic dewaxing, improving gasoline octane ratings, catalytic cracking of gasoline, shape-selective aromatization, and methanol-to-olefin (MTO) conversion.
• Fine Chemicals: Involved in the production of chemicals like diethylene glycol, 1,4-dioxane, methyl tert-butyl ether (MTBE) from isobutene and methanol, and 3,5-dimethylpyridine.
• Environmental Protection: Effective for absorbing VOCs, removing sulfur compounds (like thiophene), phenols, trichloroethylene, NOx conversion, formaldehyde removal, and H2S treatment.
• Chemical Corrosion Protection: Known for its acid corrosion resistance, especially in handling corrosive liquids like hydrochloric acid, nitric acid, phosphoric acid, and sulfuric acid in chemical plants and pipelines.
• Electrochemical: Used in solid-state lithium polymer batteries (LPBS) and alcohol fuel cells to enhance conductivity, showing strong potential for industrial applications.
