High-temperature resistant ammonia decomposition catalyst – nickel-based catalyst is an advanced catalytic material designed for efficient ammonia breakdown in extreme thermal conditions. Engineered using optimized nickel-supported formulations, it ensures superior hydrogen yield, exceptional thermal stability, and prolonged operational lifespan for large-scale hydrogen production and industrial gas processing. This catalyst is widely used in fuel refining, ammonia purification, and petrochemical applications, offering reliable performance under high-temperature conditions while minimizing energy consumption.
Product Overview
This high-temperature resistant ammonia decomposition catalyst is specifically designed for ammonia decomposition furnaces and Claus furnaces in coke oven gas purification and recovery systems. It effectively decomposes harmful gases such as ammonia (NH₃) and hydrogen cyanide (HCN) in coke oven gas into harmless gases like nitrogen (N₂), hydrogen (H₂), and carbon dioxide (CO₂), significantly addressing environmental pollution concerns. The catalyst uses nickel as the primary active component, with magnesium oxide (MgO) as the support, and special additives to enhance its high-temperature stability and catalytic activity. It is designed to maintain high-efficiency catalytic action under harsh operating conditions. With excellent compressive strength and resistance to coking and poisoning, it is an ideal replacement for traditional German G-117 catalysts.
