This catalyst is primarily used in the CO shift process of various ammonia plants using natural gas as feedstock. It is also suitable for CO shift applications in methanol synthesis gas and town gas production.

Features: Manufactured using high-quality iron as the raw material, this iron-chromium catalyst is produced via the co-precipitation of ferrous nitrate solution and chromium trioxide. With the addition of a small amount of copper oxide and other promoters, the product is mainly composed of γ-Fe2O3. It features high activity, low steam consumption, a wide reaction temperature range, resistance to thermal aging, and low intrinsic sulfur content (eliminating the need for sulfur release time during initial start-up). After reduction, it maintains stable strength, is resistant to pulverization, and offers a long service life.

a. Excellent Low-Temperature Activity: It shows significant activity starting at 230℃. An ideal shift conversion rate can be achieved with a converter inlet temperature of 250–300℃, and it recovers easily after short-term start-ups and shutdowns.

b. High Mechanical Strength: It is resistant to fragmentation and pulverization during long-term use. With excellent resistance to boiling water, it is highly suitable for medium and high-pressure production units.

c. Wide Reaction Temperature Range: The catalyst offers excellent operational flexibility. It can be operated at any temperature within the bed temperature range of 260–500℃ without affecting its catalytic activity or lifespan.

d. Low Steam Consumption: Due to its high activity and wide temperature range, the amount of steam required can be minimized.
