Sulfur-resistant shift catalyst is a high-performance catalytic material designed for efficient carbon monoxide conversion while maintaining strong resistance to sulfur contamination. Engineered using specialized metal oxide formulations, it ensures superior thermal stability, optimized reaction kinetics, and prolonged operational lifespan in hydrogen-rich environments. This catalyst is widely used in hydrogen production, ammonia synthesis, petrochemical refining, and industrial gas purification processes, providing reliable performance in sulfur-exposed applications while preventing deactivation.
Product Overview
The sulfur-resistant shift catalyst is designed using cobalt (Co) and molybdenum (Mo) as the primary active metal components, specifically for high-sulfur gas conversion processes. This catalyst exhibits excellent stability and activity in high-sulfur environments, effectively catalyzing the reaction between carbon monoxide and steam to generate hydrogen and carbon dioxide. After 6000 hours of industrial side-stream testing and 2 years of industrial unit testing, the catalyst demonstrated outstanding sulfur resistance and catalytic activity during long-term operation.
