High temperature carbon monoxide shift catalyst helps convert carbon monoxide and steam into carbon dioxide and hydrogen in synthesis gas processing. For wholesale purchasing, buyers should match catalyst chemistry, operating conditions, physical dimensions, and quality documentation to the plant’s reactor and gas composition—not select on price alone. This guide explains the main specifications to request, where the catalyst is used, how to compare suppliers, and what information to include in a quotation enquiry. At SCST, we work with B2B buyers to review project requirements and discuss suitable supply options.
This guide is intended for procurement teams, process engineers, EPC contractors, distributors, and plant operators sourcing high temperature CO shift catalyst wholesale. It is relevant to projects involving hydrogen production, ammonia and methanol synthesis gas, refinery hydrogen, and other gas-processing operations where carbon monoxide conversion is required. The article is a sourcing and specification overview, not a substitute for process design or catalyst vendor approval. Buyers should confirm final operating limits and handling requirements with their process licensor or engineering team.
High temperature CO shift catalyst promotes the water-gas shift reaction: carbon monoxide reacts with steam to form carbon dioxide and hydrogen. The reaction is exothermic, and its stoichiometry requires one mole of water per mole of carbon monoxide converted. Under standard reference conditions, the reaction releases approximately 41 kJ per mole of CO converted; actual reactor heat balances depend on operating conditions and conversion.
Commercial HTS catalysts are commonly iron-based, often using chromium oxide as a promoter. The catalyst provides active surface area and supports reaction rates suitable for the high-temperature stage of a shift process. A plant may use HTS as a standalone shift stage or ahead of a lower-temperature shift stage, depending on its process configuration and target gas composition.
Iron-chromium formulations are widely associated with conventional high-temperature shift service. The exact oxide composition, promoters, manufacturing method, and activation requirements can differ by product, so buyers should request the grade-specific technical data sheet rather than infer composition from a generic product description. Also confirm whether the supplied material is ready for loading or requires a defined reduction or activation procedure before operation.
Physical form matters because it affects loading, bed arrangement, and pressure drop. Some commercial catalyst designs use formed pellets in the several-millimeter range; for example, 5–10 mm is a useful reference range to discuss, not a universal specification. Ask the supplier to confirm the actual shape, nominal dimensions, tolerances, bulk density, and recommended loading practice for the offered grade.
| Specification area | What buyers should request | Why it matters |
|---|---|---|
| Chemistry and grade | Product designation, main active components, promoter information, and applicable technical data sheet | Confirms that the material is intended for the buyer’s process and service conditions. |
| Operating envelope | Supplier-stated temperature, pressure, steam-to-gas, and gas composition limits | Supports technical review against the reactor design and process licensor requirements. |
| Physical properties | Shape, dimensions, crushing strength, bulk density, and relevant handling information | Helps estimate bed volume, loading method, and mechanical suitability. |
| Quality and documentation | Available inspection records, batch identification, packaging details, and safety documentation | Enables receiving checks, traceability, and safe handling planning. |
Operating temperature should be reviewed in the context of the complete process. A range around 300–450°C is often used as an indicative planning reference for high-temperature shift service, but it is not a guaranteed limit or a specification for every catalyst grade. The actual inlet and outlet conditions must be checked against the vendor’s confirmed data and the plant’s design basis.
HTS catalysts are used in synthesis gas processing to reduce carbon monoxide and increase hydrogen content. Typical application discussions include hydrogen plants, ammonia and methanol feed-gas preparation, and refinery or chemical processes that require conditioned synthesis gas. The required conversion, gas composition, steam availability, contaminants, and downstream equipment all influence catalyst selection.

For an existing reactor, share the vessel dimensions, catalyst bed arrangement, current catalyst information where available, and operating history. For a new project, provide the design gas composition and process targets, along with the intended startup and operating procedure. A supplier can then assess whether the requested catalyst form and grade are a reasonable fit for further technical review.
Include the application, annual or initial requirement, target delivery location, reactor information, feed-gas composition, temperature, pressure, and steam conditions. Identify whether the enquiry is for a new unit, a planned turnaround, or replacement of an existing charge. If some details are confidential or not yet finalized, state the assumptions clearly so the supplier can identify what remains open.
Request the same information from each shortlisted supplier: grade, physical properties, operating guidance, documentation, packing configuration, and any special handling instructions. A lower unit price may not represent a like-for-like offer if the catalyst dimensions, packaging, or stated service conditions differ. Ask for clarification wherever the quotation uses a generic description without a matching technical data sheet.
Wholesale pricing, minimum order quantity, production lead time, and shipping schedule vary with grade, order volume, packaging, and destination. Ask the supplier to separate product pricing from freight, export packing, and other quoted charges where applicable. Confirm the quotation validity, payment terms, delivery basis, and what documents will accompany the shipment before issuing a purchase order.
Check whether the supplier can answer technical questions, provide consistent product identification, and communicate practical requirements for packaging and shipment. For a project order, establish who will handle document review, order updates, and delivery coordination. Request only documents that are relevant to your company’s approval process, and verify that any stated quality or compliance information applies to the offered product and batch.
SCST supports B2B enquiries for high temperature CO shift catalyst supply. To help us review a requirement, share the intended application, quantity, destination, reactor or project status, and the process conditions available to your team. We can discuss product information, quotation scope, packaging, and delivery considerations based on the details provided.
Where the process basis is still under development, identify the values as preliminary and note which specifications remain subject to engineering confirmation. This helps keep technical review separate from commercial assumptions and reduces the risk of comparing offers built on different requirements. Final catalyst selection and operating procedures should be approved by the responsible process engineer or licensor.
The right high temperature CO shift catalyst is the grade whose confirmed specifications match the process, reactor, and project requirements—not simply the product with the lowest quoted price. Begin with a complete technical enquiry, compare like-for-like documents, and verify MOQ, lead time, packaging, delivery terms, and supplier support before placing an order. For a tailored wholesale discussion, contact SCST with your application, required quantity, destination, and available process data so we can review the enquiry and outline appropriate next steps.
