Description

Zeolite, Hs-690, Hydrogen Mordenite is a synthetic aluminosilicate molecular sieve characterized by its high silica-to-alumina ratio and acidic proton sites. This material matters for its exceptional thermal stability, shape-selective catalytic properties, and high adsorption capacity, making it a critical component in demanding industrial processes. It is primarily needed by manufacturers in the petrochemical, refining, and fine chemical synthesis sectors for applications such as isomerization, alkylation, and hydrocarbon separation.

Application

• Catalytic Processes: As a solid acid catalyst in isomerization of C8 aromatics (e.g., xylene isomerization) and alkylation reactions.
• Adsorption & Separation: For the selective adsorption and purification of gases and liquids, including drying of natural gas and separation of normal paraffins from iso-paraffins.
• Petroleum Refining: Used in hydrocracking and dewaxing processes to improve fuel yields and cold flow properties.
• Chemical Synthesis: As a catalyst support or active component in the synthesis of fine chemicals and intermediates.
• Environmental Remediation: For the capture and removal of volatile organic compounds (VOCs) and other pollutants from industrial streams.

Quality Control

Our Zeolite, Hs-690, Hydrogen Mordenite is manufactured under a stringent quality management system. Each batch is tested to ensure consistent catalytic performance, acidity, and structural integrity. Key parameters including SiO2/Al2O3 ratio, crystallinity, and sodium content are verified. Certificates of Analysis (COA) detailing these specifications are available upon request.

Storage

Preserve in a tightly closed container, protected from light. Due to its hygroscopic (moisture-sensitive) nature, the product must be stored in a cool, dry place at room temperature (15-25°C). For long-term storage, keep under an inert atmosphere or in a desiccator to prevent adsorption of moisture and CO2, which can affect catalytic activity.
