Z317/Z318 Catalysts in a Refinery Hydrogen Production Project
In April 2024, SYAMCAT provided on-site catalyst loading support for a refinery hydrogen production project involving Z317 and Z318. The case describes the application context and site service. Its grade selection and loading arrangement are specific to that unit and should not be applied to another reformer without technical review.
Refinery Project and Process Context
The project account describes a refinery hydrogen production unit with a reported capacity of 20,000 Nm³/h and dry gas as its feedstock. In early April 2024, SYAMCAT's technical team attended the site to support catalyst loading.
The case concerned the unit's specified catalyst requirements and the technical proposal associated with the tender. The reported unit capacity is project background, not a capacity rating or performance guarantee for an individual catalyst grade.
Grade Identification and Loading Review
Z317 and Z318 were the grades identified in the project account. The applicable catalyst specification, reactor configuration and loading design must be checked together when assessing either grade for another unit.
A loading arrangement should identify the exact grade, its location in the reactor, the loading quantity and the basis for the proposed combination. Those details belong to the project-specific loading plan. This article does not prescribe a standard tube count, loading ratio or grade distribution for other reformers.
Site Technical Service and Reported Outcome
The published account states that catalyst loading was followed by a smooth startup and end-user review. It records the completion of the site support activity and the customer's positive response to the technical service.
Startup completion and service feedback should be distinguished from long-term catalyst performance. This case does not provide a subsequent operating dataset, a measured energy-saving comparison or a universal service-life commitment.
Using the Case for a New Hydrogen Project
For a new loading or replacement enquiry, provide the actual process information rather than applying a previous project's arrangement directly:
- Feed gas source, composition, impurity analysis and upstream treatment
- Reformer type, reactor or tube dimensions and the number of tubes or vessels
- Operating temperatures, pressure, gas flow and the applicable steam-to-carbon basis
- Current catalyst grades, quantities, loading arrangement and replacement objectives
- Required technical documents, site support scope and acceptance criteria
The steam reforming catalyst procurement guide provides related enquiry considerations. Confirm the grade and loading requirements with the SYAMCAT technical team for the actual unit.
