Production Process of SYAMCAT Secondary Steam Reforming Catalyst

 Active Component Preparation: Begin by dissolving nickel nitrate, the active component, to ensure optimal temperature resistance and stability.
 Incorporating High-Temperature Stability: Recognizing the need for stability at high temperatures (1300-1400℃), this catalyst is engineered not to fuse or deform.
 Precipitation Method: Utilize the precipitation method to create the catalyst, involving the addition of α-Al2O3 powder to the nickel nitrate solution.
 Neutralization and Precipitation: Achieve the desired catalyst properties by neutralizing the mixture with potassium carbonate, then precipitating it to form the base catalyst.
 Drying and Roasting: The catalyst base is then carefully dried and roasted to achieve the desired properties.
 Addition of Stabilizers: To enhance stability, add calcium aluminate cement and graphite, ensuring the catalyst's structural integrity.
 Mixing, Kneading, and Molding: Carefully mix, knead, and mold the catalyst material to the desired shape for uniform performance.
 Final Drying: The shaped catalyst is dried to perfection, resulting in the finished product, ready for use in the demanding environment of secondary steam reforming.

SYAMCAT Ammonia Secondary Steam Reforming Catalyst Solution

In hydrocarbon steam reforming to ammonia and methanol syngas plants, the purpose of the secondary steam reforming is to further reform the residual methane of the primary reforming gas to meet the syngas requirements. The secondary conversion is the worst working condition equipment, the catalyst in the conversion furnace for a long time in the high temperature and high pressure conditions. 

At the top of the secondary steam reforming furnace, the temperature of the oxygen (air) mixed with the primary steam reforming gas is about 1260°C. If there is any problem with the mixer or the airflow distribution is not uniform, the local maximum temperature can be up to 1980°C. The catalyst in the secondary steam reforming furnace is under such high temperature and pressure conditions. The catalyst of the secondary steam reforming is equivalent to being sintered under such working conditions, and the pore structure, specific surface and other physical properties of the catalyst may undergo large changes, which will have a greater impact on the performance of the catalyst, especially the activity.

FAQs of SYAMCAT Secondary Steam Reforming Catalyst

Q:
How many years is the service life of your secondary steam reforming catalyst?
A:  

Usually it's more than 5 years. In order to prolong the service life of the catalyst, the operating parameters such as temperature, pressure, H2O/C ratio should be maintained stable, times of startups and shutdowns should also be lessened, as well as times of oxidation-reduction of the catalysts.During operation, light up all the burners (no mis-lighting or uneven burning) as far as possible to keep even and stable heating; observe the tube color frequently, measure tube wall temperature regularly, and find out and treat hot band, hot spot or hot tube in time. The temperature difference between each exit spot of the reformer should be kept within 20℃.
Q:
What is the inlet temperature to the catalyst bed?
A:
There is a great influence of temperature on the reduction process. No matter it is considered from nickel reduction equilibrium, or ammonia cracking equilibrium, or the reaction rate, it is always beneficial to raise temperature. In the whole reduction period, the inlet temperature of the catalyst bed should be kept as high as possible, generally, in the range of 450-650℃.
