Catalyst Additives Research: Catalyst Breakthroughs in Iron-Based Ammonia Synthesis
In the development of iron-based ammonia synthesis catalysts, our research team has achieved remarkable breakthroughs in catalyst additives, laying a solid foundation for the outstanding performance of our company's products. Here is an in-depth exploration of the additive aspects:
Optimized Design of K2O Content
K2O, an electron-type additive, plays a crucial role in ammonia synthesis catalysts. In the development of the SYAMCAT A217 catalyst, our research team conducted a thorough analysis of the relationship between K2O content and catalyst specific activity.
By strategically increasing the K2O content, effective enhancement of the catalyst's specific activity was achieved. This unique design not only boosts the catalyst's activity but also establishes SYAMCAT A217 as a leader in the industry.
Introduction of Cobalt Oxide for Catalyst Performance
The introduction of cobalt oxide into iron-based catalysts is a significant innovation. Our research team discovered that cobalt oxide forms a eutectic with magnetite. After reduction, cobalt atoms are uniformly distributed in α-Fe, reducing α-Fe grain size significantly and promoting the formation of more active centers.
This design not only enhances the catalyst's activity but also plays a positive role in optimizing the pore structure, providing robust support for the efficient performance of the catalyst.
Synergistic Action of Structural Additives Al2O3 and CaO
Al2O3 and CaO, as structural additives, play a crucial role in the stability and activity of the catalyst. Our research team carefully adjusted the content of these two additives, forming a eutectic to ensure the uniform distribution of metal ions in magnetite.
This stabilizes the grain size and enhances the catalyst's activity and stability. While SYAMCAT A217 catalyst significantly reduces the content of Al2O3 and CaO compared to other similar catalysts, the synergistic action of additives still maintains excellent performance.
Introduction of Special Additives for Enhanced Thermal Stability
To compensate for the potential decrease in thermal stability due to lower Al2O3 and CaO content, our company introduced a special additive.
This electron-donating/accepting additive plays a crucial role in preventing the transfer of soluble potassium salts to the catalyst particles, effectively extending the catalyst's thermal stability and service life. Additionally, this special additive demonstrates outstanding resistance to poisoning, ensuring superior catalyst performance even under high H2 conditions.
Through in-depth research into the mechanism of additives, skillful adjustment of additive content, SYAMCAT has successfully overcome the performance bottlenecks of ammonia synthesis catalysts, laying a robust foundation for greater success in the market.
