Primary Steam Reforming Catalyst for Natural Gas
Applications
1. Synthesis gas progress : Used in steam reforming process to produce hydrogen, ammonia synthesis gas, methanol synthesis gas, oxo- synthesis gas, carbon monoxide with gaseous hydrocarbon feedstock.
2. A wide range of feedstock: Adapt to natural gas, oil field associated gas and other gaseous hydrocarbon feedstock, which can be used alone or in combination.
3. Various types of tubular reformers: Suitable for various types of tubular reformers with top-fired, side-fired or bottom- firebox,SYAMCAT Z428Q should be loaded in the upper section of the reformer tubes in combination while SYAMCAT Z429Q which is loaded in the lower section.
4. Special Application: SYAMCAT Z429Q can be used alone for the whole tube loading.

Features
1. Excellent reforming activity, the proprietary carrier modification technique makes active components more firmly bound to the support, leading to better catalysts stability in both activity and structure.
2. The catalyst shape of 4-hole cylinder with dome provides it with large external geometric surface area, higher porosity, lower pressure drop, and better gas flow distribution etc..
3. Excellent reducibility: through self- circulation reduction, natural gas feedstock can be directly introduced into the reformer without extra activation in advance.
4. Excellent anti-poisoning and regeneration properties: can be self- renewal by optimizing operation conditions when sightly poisoned by sulfur or chlorine, while in-situ regeneration can be performed when poisoned seriously.
5. Suitable for pre- reforming combined with reforming process.
6. Patented product and awarded the National Prize for Science and Technology Progress.
7. Strong resistance to poisoning, user-friendly regeneration, user can regenerate by optimising the operating parameters, or in-reactor regeneration.
8. When using natural gas raw material, it can be directly fed, or self-circulating reduction activation, convenient operation, saving start-up time.
Cost-Efficient Stability: Our catalyst, fortified by a proprietary carrier modification technique, ensures exceptional reforming activity. Firmly binding active components to the support enhances both stability and efficiency, leading to significant cost savings in catalyst replacements and maintenance.
