Choose a methanation catalyst supplier by checking whether its product and technical support match your feed composition, reactor design, operating conditions, and project stage. A credible supplier should be able to discuss catalyst options against your process requirements, explain what information is needed for evaluation, and clarify product specifications, handling, supply scope, and follow-up support. Do not compare suppliers on price alone: a catalyst that is not suited to the actual feed or operating profile may create additional process and procurement risks. Below, we outline a practical way to evaluate suppliers for both CO and CO₂ methanation projects.

Before contacting suppliers, prepare a concise process brief. Include the target reaction, gas composition, expected flow range, pressure and temperature conditions, contaminants, reactor type, and whether the project is at laboratory, pilot, or commercial scale. If some values are not yet confirmed, identify them as estimates rather than presenting them as fixed design conditions.
CO and CO₂ methanation are related reactions, but their hydrogen requirements differ. The ideal stoichiometric reaction for CO methanation is CO + 3H₂ → CH₄ + H₂O, which requires 3 mol H₂ per 1 mol CO. For CO₂ methanation, the ideal reaction is CO₂ + 4H₂ → CH₄ + 2H₂O, requiring 4 mol H₂ per 1 mol CO₂.
These ratios are reaction stoichiometry, not guaranteed plant operating ratios or catalyst performance data. Actual process design may account for equilibrium, side reactions, feed variation, heat management, and downstream requirements. Ask each supplier how it evaluates the specific reaction and feed you plan to use, and avoid treating a recommendation for one gas composition as automatically suitable for another.
List known impurities and expected fluctuations in the feed, since these can influence catalyst selection and operating strategy. Also share the reactor configuration and any limits on pressure drop, temperature control, or catalyst loading. A supplier cannot responsibly assess fit from the words “CO methanation” or “CO₂ methanation” alone.
Ask suppliers to explain the basis for their proposed catalyst, including intended application, product form, and relevant operating considerations. Request a specification sheet and clarify which properties are controlled, which are typical values, and which depend on the production batch. Where performance data are offered, confirm the test conditions and whether they resemble your process conditions.
Relevant product information may include composition, physical form, size range, bulk density, mechanical properties, packaging, and recommended handling. The exact items that matter depend on reactor design and project requirements, so compare suppliers against the same specification checklist. If a value is not available or is not applicable, ask the supplier to state that clearly rather than assuming equivalence.
For operating guidance, ask how the supplier expects the catalyst to be stored, loaded, activated, and handled, where those instructions are within its scope. Confirm whether the supplier provides application guidance or only the catalyst product. This distinction helps your engineering team identify who is responsible for each technical decision.
Performance claims are meaningful only when their test basis is clear. Request the relevant gas composition, pressure, temperature, space velocity or flow basis, catalyst quantity, test duration, and measurement method when a supplier refers to conversion, selectivity, or stability. Compare like with like, and do not assume laboratory results predict commercial performance without process-specific evaluation.
For example, a stated operating temperature of 300 °C is useful only if you know the test setup and conditions behind it. It should not be treated as a universal set point for every reactor or catalyst. Ask suppliers to explain the limits of their data and what additional validation may be needed for your project.
A supplier evaluation should cover technical communication, product consistency, documentation, production and delivery planning, and responsiveness after the quotation. Ask who will handle technical questions and how changes to the order or specification are managed. For a project with defined milestones, confirm expected lead time and the assumptions behind it before placing an order.

Request the same information from each candidate so you can compare responses fairly. If a supplier gives a quick recommendation without asking for basic process details, treat that as a reason to request clarification. A careful supplier should be willing to identify information gaps and distinguish confirmed facts from preliminary guidance.
Compare quotations on a like-for-like basis, including catalyst quantity, product specification, packaging, shipping assumptions, and any technical services included. A lower unit price may not represent a lower project cost if the product form, delivery scope, or support differs. Ask whether the quotation is based on your stated requirements or on a standard product assumption.
Discuss order quantity and delivery schedule early, especially when the project includes staged trials or scale-up. Confirm whether the supplier can support the required quantity and whether the proposed schedule depends on specification approval, production planning, or other conditions. Keep any unconfirmed dates or quantities documented as estimates until the supplier confirms them.
Price and headline performance figures are insufficient without a comparable technical basis. A quoted number may come from different test conditions, and product descriptions may use different measurement or reporting conventions. Ask for the underlying conditions and compare the total supply scope before ranking offers.
Incomplete feed data can lead to generic recommendations that do not address the project’s actual constraints. Share what is known, label unknowns, and explain which parameters are still being developed. If the design is preliminary, ask for a preliminary assessment and identify what must be confirmed before final selection.
Do not assume that a catalyst supplier is also responsible for reactor design, process guarantees, commissioning, or plant troubleshooting. Confirm in writing which services are included and which remain with the buyer, EPC contractor, or process licensor. Clear boundaries help prevent mismatched expectations during procurement and project execution.
At Sichuan Shutai, we supply industrial catalyst products and welcome technical discussions about methanation catalyst requirements. To help us assess a request, send the target reaction, feed composition, operating conditions, reactor information, project stage, required quantity, and preferred delivery schedule. If any information is preliminary, mark it accordingly so we can discuss the request with the right level of caution.
We can clarify product options, available specifications, supply scope, and the information needed to evaluate potential fit. For performance-related questions, provide the test or process conditions you need to meet so that the discussion stays tied to your application rather than a general claim. Product suitability and operating decisions should be confirmed against the complete project design.
The right methanation catalyst supplier is one that can connect its product information and support to your actual CO or CO₂ process—not simply provide a low quote or broad performance claim. Begin with a complete process brief, verify technical evidence under relevant conditions, and compare specifications, quality communication, delivery assumptions, and support scope. Keep the stoichiometric distinction in view: the ideal reaction requires 3 mol H₂ per 1 mol CO or 4 mol H₂ per 1 mol CO₂, while actual operating needs depend on process design.
Your next step is to prepare the feed and reactor data, then request a written technical and commercial response from shortlisted suppliers. Share those requirements with Sichuan Shutai to discuss available catalyst options and supply details for your project. A clear, evidence-based comparison will help your team move from initial inquiry to a more informed sourcing decision.
