Description

Zeolite, Type: ZSM-5 is a high-silica, shape-selective aluminosilicate molecular sieve with a distinctive pentasil framework structure. This material is critically valued for its exceptional catalytic activity, thermal stability, and precise pore size, which enables selective separation and conversion of molecules. It is an indispensable component for process engineers and R&D teams in the petrochemical, refining, and fine chemical synthesis industries.

Application

• Catalytic Cracking & Hydrocracking: As a key catalyst component in fluid catalytic cracking (FCC) units and hydrocracking processes to upgrade heavy petroleum fractions into valuable fuels and light olefins.
• Xylene Isomer Separation: For the selective adsorption and separation of para-xylene from its isomers in the production of purified terephthalic acid (PTA) for polyester.
• Methanol-to-Olefins (MTO) & Methanol-to-Gasoline (MTG): Serving as the primary catalyst for converting methanol into ethylene, propylene, or high-octane gasoline.
• Selective Catalytic Reduction (SCR): Used as a catalyst support or component in SCR systems for reducing nitrogen oxide (NOx) emissions from diesel engines and industrial boilers.
• Fine Chemical & Pharmaceutical Synthesis: As a solid acid catalyst for alkylation, isomerization, and acylation reactions, offering advantages in product separation and catalyst reusability.
• Adsorption & Drying: For the selective removal of water, CO2, or other impurities from gas streams due to its high adsorption capacity and hydrophobicity.
• Environmental Remediation: In the adsorption of volatile organic compounds (VOCs) and other pollutants from air and wastewater streams.

Quality Control

Our ZSM-5 Zeolite is manufactured under a stringent quality management system. Each batch undergoes comprehensive analysis to ensure consistent performance in catalytic and adsorption applications. Key parameters such as silica-to-alumina ratio (SAR), crystallinity, surface area, and acidity are rigorously controlled. A Certificate of Analysis (COA) detailing specific lot results is provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Due to its hygroscopic nature, this material must be stored in a cool, dry place at room temperature (15-25°C/59-77°F) with low humidity. For long-term storage, consider using a desiccator or inert atmosphere packaging to prevent moisture uptake, which can affect catalytic performance.
