Description

ZSM-5 is a high-performance, synthetic zeolite molecular sieve belonging to the pentasil family, renowned for its unique three-dimensional pore structure and exceptional shape-selective catalytic properties. This material is a cornerstone in modern petrochemical and refining processes, enabling precise control over reaction pathways for superior product yields and selectivity. It is an essential component for catalyst manufacturers, R&D laboratories, and industrial plants operating in the fields of hydrocarbon conversion, fine chemical synthesis, and environmental catalysis.

Application

• Catalytic Cracking & Hydrocracking: Key catalyst component in fluid catalytic cracking (FCC) and hydrocracking units to enhance gasoline octane and diesel yield.
• Xylene Isomerization: Selectively catalyzes the conversion of ethylbenzene and meta-xylene to high-value para-xylene, a primary precursor for PET production.
• Methanol-to-Olefins (MTO) & Methanol-to-Gasoline (MTG): Serves as the principal catalyst for converting methanol into light olefins (ethylene, propylene) or high-octane gasoline.
• Selective Catalytic Reduction (SCR): Used as a catalyst support or active component in NOx removal systems for automotive and stationary emission control.
• Alkylation & Disproportionation: Catalyzes reactions such as benzene alkylation with ethylene to produce ethylbenzene and toluene disproportionation.
• Adsorption & Separation: Employed in pressure swing adsorption (PSA) units for the separation of linear from branched paraffins or for drying gases.
• Fine Chemical Synthesis: Facilitates shape-selective acid-catalyzed reactions in the synthesis of pharmaceuticals, agrochemicals, and fragrances.
• Environmental Remediation: Used as an adsorbent or catalyst for the removal of volatile organic compounds (VOCs) and other pollutants from waste streams.

Quality Control

Our ZSM-5 is manufactured under stringent process controls to ensure batch-to-batch consistency and performance reliability. Quality is verified through a comprehensive suite of analytical techniques including X-ray diffraction (XRD), nitrogen physisorption (BET/BJH), scanning electron microscopy (SEM), and chemical analysis for SiO2/Al2O3 ratio and cation exchange capacity. Certificates of Analysis (COA) detailing specific lot parameters are provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. This material is hygroscopic (moisture-sensitive) and must be stored in a cool, dry place at room temperature (15-25°C/59-77°F) under low humidity conditions. Opened containers should be flushed with an inert gas (e.g., nitrogen or argon) and resealed immediately to prevent moisture uptake and maintain catalytic activity.
