Refinery and petrochemical process units with catalyst sample trays

Process applications

Catalyst Manufacturer Requirements by Process Context

Translate the unit, feed and reload plan into a purchase brief a catalyst manufacturer can answer. Assay, particle size, pack and destination stay on the RFQ; performance outcomes stay with the buyer’s engineers.

Application to RFQ

Same specialty family, different purchase questions

A catalyst manufacturer RFQ should name the process so factories know which assay and particle questions matter, without treating a family name as proof of fit.

Fluid catalytic cracking makeup

Record whether the need is equilibrium makeup, additive or a trial lot. Ask for activity window, particle-size distribution, attrition questions, moisture and pack. Keep circulating-inventory claims out of the quotation until the buyer’s process team defines them.

Hydroprocessing reload

State active metals, shape, size, crush-strength questions, sulfur or nitrogen duty as a buyer note, and whether the lot is a full reload or a top-up. Density, moisture and packaging still need factory answers.

Polymerization and specialty synthesis

Ionic type, residual metals, carrier and moisture often dominate. Ask for pH, density and sample size. Do not copy a competitor’s conversion figure into this brief.

Distribution and toll blending

Focus on assay range, pack size, labeling language, destination mix and document set. Recurring forecasts should still list a quantity unit and a first-lot sample rule.

Selection trade-offs to keep visible

Buyers often face a tension between a tightly specified grade and a broader family substitution. A tighter assay, particle-size or residual-metal window can reduce process risk while shrinking the factory set and raising minimum-order or sample cost. A broader window can increase quote coverage while leaving more confirmation work for EHS and quality. Another tension is unit price versus delivered total: an apparent low kilogram price can reverse after packaging, testing, freight, duties and destination handling are stated. This page does not pick a side; it asks both numbers to stay on the comparison sheet.

Still open after process mapping

Documents the process team still has to request

  • Current SDS for the quoted concentration and form, including flash point and UN number where assigned.
  • TDS limits for assay, particle size, moisture and residual metals that the unit actually uses.
  • CoA fields the quality group will accept before unloading.
  • TSCA, REACH, GMP or ISO questions bound to the proposed supplier and product, not to this website.
  • DOT or IMDG class confirmed against the SDS and the carrier, not against a product-family brochure.
