Reforming catalyst requirements differ because each plant needs a different downstream gas composition, operating strategy, and response to contaminants. Hydrogen plants prioritize hydrogen yield and integration with purification; ammonia plants need synthesis gas suitable for a controlled hydrogen-to-nitrogen ratio; and methanol plants need gas whose composition supports methanol synthesis. In all three cases, catalyst selection must be matched to the feed, reformer design, operating conditions, and the full process sequence—not just the product name.
As a catalyst supplier, we recommend starting with process data: feed composition, sulfur-removal performance, steam-to-carbon ratio, pressure, temperature profile, and the required outlet-gas composition. These factors determine whether a catalyst is suitable and what performance criteria should be compared. The figures below are screening references, not universal design specifications; the licensor’s process basis and plant operating limits should govern final selection.
In steam reforming, a catalyst promotes reactions between hydrocarbons and steam to produce hydrogen, carbon monoxide, and carbon dioxide. For methane, the simplified primary reaction is CH4 + H2O ⇌ CO + 3H2; the water-gas shift reaction can then convert CO and steam into additional hydrogen and CO2. Actual plant gas composition depends on feed, conditions, and the downstream process.
Many conventional hydrocarbon steam-reforming applications use nickel-based catalysts. Their suitability depends on such factors as feed cleanliness, resistance to deactivation, heat transfer, pressure drop, mechanical strength, and how the catalyst fits the reformer tubes or other reactor configuration. A catalyst that performs well in one process may not be the right choice in another because the process objective and operating envelope differ.
For a hydrogen plant, the reforming section is usually evaluated as part of a production train that may include shift conversion, gas cooling, and hydrogen purification. Buyers therefore need to assess more than reformer outlet hydrogen concentration: the catalyst must fit the plant’s feed and operating conditions while supporting the required performance of the downstream units. Where hydrogen purity is the final target, purification technology and its operating requirements also affect the overall process design.
Feed contaminants are a central selection issue. Sulfur compounds can deactivate many reforming catalysts, so buyers should confirm the feed specification and the performance basis for upstream sulfur removal rather than assume the catalyst can tolerate untreated feed. Steam availability, carbon-formation risk, heat flux, and turndown requirements also need to be reviewed with the reformer designer.
An ammonia plant needs hydrogen and nitrogen for ammonia synthesis, so reforming catalyst evaluation must account for the gas balance across the whole front end. The ideal synthesis stoichiometry is 3 moles of hydrogen per mole of nitrogen. This 3:1 molar ratio is a process target for the synthesis reaction, not a stand-alone specification for reformer outlet gas; air addition, secondary reforming, shift conversion, and gas purification all influence the final synthesis-gas composition.
For this reason, an ammonia buyer should evaluate catalyst options against the plant’s primary and secondary reforming arrangement, feedstock, and required gas composition after relevant process steps. Activity and stability matter, but so do pressure drop, mechanical integrity, and compatibility with the reactor’s temperature profile. The best catalyst choice is the one that supports the complete ammonia front-end design rather than maximizing hydrogen at an isolated point in the process.
Methanol production needs syngas with a composition appropriate for methanol synthesis. That means the buyer should assess the balance of hydrogen, carbon monoxide, and carbon dioxide, along with the downstream synthesis design. A reforming catalyst selected only to maximize hydrogen may not deliver the gas composition the methanol process requires.

Methanol plants can use different reforming configurations, including steam reforming and combined approaches, depending on plant design and feed. This changes the catalyst duty and the importance of syngas composition, heat integration, and operating flexibility. Buyers should provide the intended process configuration and target gas composition when requesting a catalyst proposal.
| Evaluation area | Hydrogen plant | Ammonia plant | Methanol plant |
|---|---|---|---|
| Primary process focus | Hydrogen production and purification integration | Front-end gas balance for ammonia synthesis | Syngas composition for methanol synthesis |
| Important downstream connection | Shift conversion and hydrogen separation, where used | Secondary reforming, gas conditioning, and synthesis loop | Syngas conditioning and methanol synthesis loop |
| Key catalyst questions | Feed cleanliness, conversion, stability, and purification needs | Reformer configuration, gas balance, pressure drop, and stability | Feed and configuration fit, syngas balance, and operating flexibility |
Operating figures are useful for screening, but they must be checked against the actual process design. Conventional steam reforming is commonly associated with high-temperature operation; a broad preliminary reference is approximately 700–900 °C, while the relevant catalyst-bed temperature profile depends on the reformer and process. This range is not a guaranteed operating window for every catalyst or plant.
Steam-to-carbon ratio is another important input because it affects reforming conditions and carbon-formation risk. A preliminary screening range sometimes used for conventional steam reforming is about 2.5–3.5 mol of steam per mol of carbon in the feed, but the appropriate value depends on feed composition, pressure, catalyst, and plant design. Buyers should also confirm pressure and expected throughput with the process licensor instead of treating generic values as a catalyst guarantee.
For ammonia projects, the 3:1 hydrogen-to-nitrogen molar ratio provides a clear downstream stoichiometric reference, but it does not replace a complete gas-balance calculation. For methanol, buyers should provide the process’s specified syngas target or relevant composition criterion. For hydrogen, define the product purity and capacity requirement at the purification-unit boundary so reforming performance is compared on a consistent basis.
Provide feed composition, contaminant levels, flow rate, pressure, temperature profile, steam-to-carbon ratio, and the reformer type. Include start-up, shutdown, and turndown expectations when they are relevant to the project. Missing operating information makes it difficult to distinguish a genuine catalyst fit from a proposal based on assumptions.
Ask suppliers to state the conditions behind quoted activity or performance information, including feed assumptions and test or design basis where available. Review catalyst dimensions, loading guidance, mechanical properties, pressure-drop considerations, and any stated limits alongside activity. Do not compare values from different operating conditions as if they were equivalent.
Clarify packaging, shipping requirements, expected order quantity, production schedule, and technical documentation before procurement. Confirm whether the supplier can support loading guidance, operating questions, and troubleshooting within the scope agreed for the project. These commercial and service details matter because catalyst selection affects installation planning as well as operation.
Reforming catalyst requirements differ because hydrogen, ammonia, and methanol plants use the reformed gas for different purposes. Hydrogen projects emphasize production and purification integration; ammonia projects must support the front-end gas balance for synthesis; and methanol projects need syngas suited to methanol production. Across all three, feed cleanliness, reactor conditions, catalyst durability, and downstream process requirements shape the final choice.
As a next step, prepare a process data sheet with feed analysis, operating conditions, reformer configuration, outlet-gas targets, and project schedule. At Sichuan Shutai, we can use these details to discuss catalyst fit, product specifications, and supply requirements for your application.
