Reliable Ammonia Catalyst Solution
Primary Steam Reforming Catalyst with Higher Porosity for Ammonia Synthesis Gas
Z433/Z434 Primary Reforming Catalysts for Methanol Syngas Applications
SYAMCAT Z433 and Z434 are nickel-based primary steam reforming catalysts. This page presents the grades within our methanol plant range for process routes that include primary reforming.
In the loading arrangement described for these grades, Z433 is used in the upper tube section and Z434 in the lower section. Review the combination against the methanol plant feedstock, reformer configuration and operating conditions rather than applying a fixed loading arrangement.

Selection and Loading Considerations
Reformer Configuration
Review the reformer design, tube dimensions and required catalyst loading before selecting the catalyst combination.
Feed and Operating Conditions
Compare the feed composition, temperature, pressure and steam-to-carbon ratio with the published operating range.
Catalyst Specifications
Review catalyst shape, dimensions and bulk density alongside the loading requirements of the unit.
Startup and Operation
Confirm the reduction, startup and operating procedures against the applicable product instructions and plant requirements.
Request a Catalyst and Loading Review
Please provide the feed composition, reformer tube dimensions and quantity, inlet and outlet temperatures, operating pressure, steam-to-carbon ratio, current catalyst grades and loading arrangement. Let us know whether this is a new project or a catalyst replacement.
