Buyer's Digest
Use this page as a product-first sourcing checkpoint before sending an RFQ. Category: Hydrotreating Catalysts. Confirm application fit, capacity, materials, destination, lead time and compliance requirements before comparing suppliers.
Original product description
This paraffin hydrotreating catalyst is supplied as solid trilobe extrudates. Its stated composition is NiO–WO3–promoter–Al2O3: modified alumina serves as the carrier, while nickel, tungsten, and a special promoter are the active formulation components.
The catalyst is described for hydrotreating processes used to produce food-grade paraffin and medicine-grade petroleum jelly. Reported characteristics include high activity at low temperature, stability, compression and abrasion resistance, and convenient loading and unloading.
Regeneration and subsequent reuse are also stated. Reported physical targets include a minimum surface area of 100 m²/g, minimum pore volume of 0.30 mL/g, minimum crushing strength of 190 N/cm, particle size of Φ1.3–1.5 × 5–15 mm, and bulk density of 0.80 kg/L.
A disclosed operating example lists Daqing paraffin with a 58°C melting point and 0.8 wt% oil content as the feed. The associated conditions are 8.0 MPa hydrogen partial pressure, 240°C temperature, 1.0 hr⁻¹ space velocity, and a 400 V/V hydrogen-to-oil ratio.
The reported product results for this example are Saybolt color +30, light stability sy+3, and oil content of 0.8 wt%.
A separate statement reports that light stability may reach sy+2 or sy+1 at an operating pressure of 12 MPa;buyers should treat these as disclosed operating results rather than guaranteed performance for another feedstock or unit.
Before procurement, confirm the exact catalyst grade and current batch specification, test methods and tolerances for each physical property, required catalyst volume, reactor configuration, feed composition and contaminants, activation or start-up procedure, expected operating window, regeneration protocol, and disposal requirements.
Buyers should also request current safety and quality documentation and verify whether the reported results are applicable to their own process conditions.
