zeolite catalyst price

When sourcing zeolite catalysts, you must prioritize the Si/Al ratio (Silica-to-Alumina ratio), as it directly determines the catalyst's hydrothermal stability and acidity. Additionally, verify the Specific Surface Area (BET method), which should typically range from 300 to 700 m²/g depending on the framework type (e.g., Y, ZSM-5, or Beta). Ensure the particle size distribution aligns with your reactor type—fluidized bed reactors require microspheres (60-80 microns), while fixed-bed reactors require extrudates or pellets.

The price is heavily influenced by the pore structure and synthesis complexity. ZSM-5 is widely used for petrochemical FCC processes and environmental VOC abatement due to its medium pore size. Y-type zeolites are essential for hydrocracking, while SSZ-13 is premium-priced due to its high efficiency in SCR (Selective Catalytic Reduction) for diesel exhaust. Always match the pore diameter (measured in Angstroms) to the molecular size of your reactants to ensure shape-selective catalysis.

Suppliers must provide a comprehensive SDS (Safety Data Sheet) compliant with the GHS (Globally Harmonized System). For shipments to Europe, REACH registration is mandatory. Ensure the product has a valid CAS Number and check for ISO 9001:2015 certification to guarantee batch-to-batch consistency. If the catalyst contains precious metals (like Pt or Pd), additional export licenses and conflict-free mineral declarations may be required.

Request a Certificate of Analysis (COA) for the specific batch and ask for pilot-scale test data. Key performance indicators include conversion rate, selectivity percentage, and deactivation rate. It is highly recommended to perform a TPD (Temperature Programmed Desorption) test to analyze acid site strength. For long-term economic feasibility, inquire about the regeneration cycles—a high-quality zeolite should maintain structural integrity after multiple calcination or steaming recovery processes.

Zeolites are highly hygroscopic (moisture-absorbent). You must mandate vacuum-sealed moisture-proof packaging, typically using PP woven bags with PE inner liners or steel drums with airtight seals. Ensure the shipping container includes industrial-grade desiccant packs and request FCL (Full Container Load) shipping to minimize handling and exposure to humid air at transshipment hubs.

Focus on the active component content rather than just the gross weight. Negotiate based on volume-tiered pricing; for instance, orders exceeding 5-10 metric tons usually trigger a 10-15% discount. For long-term contracts, suggest a formula-based pricing model linked to the market price of raw materials like sodium aluminate or tetrapropylammonium hydroxide (TPAOH) to ensure price stability.

Always prioritize Audited Suppliers on Made-in-China.com who have undergone third-party verification by agencies like SGS or Bureau Veritas. Utilize the Secured Trading Service to ensure payments are only released upon confirmation of shipping documents. Before final payment, hire a third-party inspection service to conduct random sampling at the factory to verify the crystallinity and chemical composition against the agreed specifications.

While most synthetic zeolites are classified as non-hazardous chemicals, you must confirm the HS Code (typically 382499 or 284210) with your customs broker to determine precise import duties and VAT. For shipping to the US or EU, ensure the supplier provides a Non-Hazardous Declaration to avoid unnecessary delays in customs 'red channels'. If the catalyst is pre-activated (reduced), it may be pyrophoric and require Class 4.2 hazardous goods handling.
