How to choose a customized catalyst solution suitable for methanol synthesis plants?

1. Prepare the Purchasing Information

• Current manufacturer, full catalyst grade and the latest available specification or technical data sheet.
• Particle dimensions, shape, tolerances and the existing loading reference where available.
• Required net mass in kg or metric tonnes, or packed catalyst volume in m³; mark confirmed and estimated quantities separately.
• Required arrival date, delivery location and terms, packaging and inspection-document requirements.

If the required volume includes support or inert materials, identify the catalyst portion separately. When converting volume to mass, confirm the bulk-density and loading basis rather than applying a universal factor.

2. Have the Technical Team Confirm the Process Data

• Synthesis-reactor inlet gas: available H₂, CO, CO₂, CH₄, N₂, water and other relevant component data, including known impurities. State units, dry or wet basis, sampling location and date.
• Temperature, pressure and flow: normal values and expected ranges, measurement locations, absolute or gauge pressure, and reference conditions for gas volumes.
• Reactor and loading: reactor configuration, relevant dimensions, bed volume or height, existing loading drawing and loading constraints.
• Targets and limits: required throughput, product-quality or performance criteria, allowable pressure drop and other project constraints, with their assessment conditions.
• Operating history: replacement reason, relevant performance records and any changes in feed, throughput or equipment.

Raw-material information such as natural gas or coal is useful background, but it does not replace the synthesis-reactor inlet-gas analysis. Label design assumptions separately from measured operating data and define any gas-ratio or space-velocity calculation provided.

3. Compare the Proposed Solution and Quotation

Send the same enquiry revision to each supplier. Compare the proposed grade, supply condition, particle specification, quantity basis, deviations and included services before comparing price. State which inspection documents and technical support are required.

SYAMCAT lists HJ323 as a copper-based methanol synthesis catalyst. Review its current technical data sheet against the project conditions. Any proposed grade, size, loading arrangement or formulation change should be confirmed explicitly in the technical response.

4. Start with the Documents Already Available

If the data are incomplete, submit the current grade, specification, estimated quantity and delivery requirement first. Mark missing values “to be confirmed” and identify the technical contact responsible for them.

Ask the supplier to list the missing information, quotation assumptions and deviations, and to distinguish an initial quotation from a completed technical selection. A quotation alone does not replace the project's technical approval.
