Buyer's Digest
Use this page as a product-first sourcing checkpoint before sending an RFQ. Category: Activated Alumina. Confirm application fit, capacity, materials, destination, lead time and compliance requirements before comparing suppliers.
Original product description
These peptizable alumina pellets are based on macroporous pseudoboehmite (AlOOH·nH2O) and are offered for shaped catalyst-support production. The stated material features a developed pore structure and can provide a platform for dispersing and anchoring active catalyst components.
Listed application areas include petrochemical processing, fine chemicals, gas purification, and environmental protection, with potential use in hydrogenation, dehydrogenation, and desulfurization catalyst systems.
The available customization window covers particle sizes from 0.2 to 6.0 mm, bulk density from 0.35 to 1.0 g/cm³, specific surface area from 8 to 350 m²/g, pore volume from 0.3 to 1.1 cm³/g, pore diameter from 8 to 30 nm, and water absorption from 40% to 130%.
Listed crystal phases include gamma, theta, and alpha alumina. Dust content is stated below 0.1%, while moisture content is stated below 1%. Crush strength depends on particle size, bulk density, and pore volume.
Listed minimum values range from above 5 N per particle for 0.5 mm material to above 100 N per particle for 4.0–5.0 mm material. Standard and high-purity grades are also described for Na2O, SO3, SiO2, Fe2O3, CaO, and related constituents, with stated limits below 0.10% and below 0.02%, respectively.
Before procurement, buyers should define the required particle-size distribution, pore characteristics, bulk density, crystal phase, water absorption, and crush-strength target for the intended catalyst formulation. The acceptable level and test method for each listed impurity should also be confirmed.
Request a specification sheet for the exact customized grade and agree on sampling, test methods, acceptance tolerances, packaging, storage conditions, and scale-up validation before placing a production order.
The stated packaging is 25 kg per bag, with custom drums also available;material should be stored sealed and away from heat and light.
