Advancements in Ammonia Synthesis: Enhancing Efficiency with SYAMCAT Steam Reforming Catalysts
Introduction to Ammonia Synthesis and Catalyst Research
Ammonia synthesis plays a crucial role in various industries, leveraging natural gas as its primary feedstock due to its abundant reserves, simple molecular structure, and high atomic utilization efficiency. In this process, after desulfurization, natural gas is mixed with water vapor and fed into a primary reformer operating at 3.6 MPa and 834°C, where most of the methane undergoes conversion into hydrogen, carbon monoxide, and carbon dioxide using nickel-based catalysts.
The Significance of Methane Steam Reforming
The essence of the primary reforming stage lies in the steam reforming reaction of methane. Methane reforming for hydrogen production offers advantages such as low cost, low carbon emissions, and wide availability of feedstocks, making it suitable for large-scale hydrogen production and providing ample hydrogen for subsequent ammonia synthesis processes.
The Role of Ni-Based Catalysts in Methane Steam Reforming
Nickel-based catalysts, such as Ni/Al2O3, are among the catalytic systems exhibiting excellent performance in methane steam reforming reactions. To prevent surface carbon deposition, alkali metal elements like sodium and potassium are often incorporated into these catalysts. However, challenges persist, including poor high-temperature stability, high nickel consumption, and limited active sites, underscoring the importance of design improvements in nickel-based catalysts for this reaction.
Research on Enhancing Stability of Ni-Based Catalysts
The research group led by Wan Huijun at Beijing University of Technology conducted studies on various catalysts to address the stability issues of nickel-based catalysts in methane steam reforming reactions. Their findings revealed that 10 wt% Ni/SBA-15 exhibited excellent activity and stability at 800°C, with no significant activity decline after 740 hours of reaction. Introducing the Ce1-xZrxO2 component enhanced nickel dispersion and improved the catalyst's oxidation-reduction performance and activity. Additionally, when FeCrAl was used as the support carrier, larger gas velocities could be employed under the same reaction conditions to achieve similar catalytic activity.
