HB-B04是一种以镁铝尖晶石为载体，含有多元复合助剂的新型CO耐硫变换催化剂，适宜于在以煤或渣油为原料制取合成氨、甲醇合成工艺气和城市煤气的变换工艺过程中使用，若在压力较高、水蒸汽分压较大而运行温度又较低，即在距离露点温度较近或是在高温低硫的苛刻条件下使用时，与同类催化剂相比，B04 更能显示出其优越的催化性能：变换活性高、活性稳定性好；对有机硫的氢解和水解能力强；抗水合性能好；烧碳再生性能优异。

HB-B04 is a novel sulfur-tolerant CO shift catalyst featuring a magnesium-aluminum spinel carrier and a multi-component composite promoter system. It is highly suitable for shift processes in the production of ammonia, methanol synthesis gas, and town gas using coal or residue oil as feedstock.

HB-B04 demonstrates superior catalytic performance compared to similar catalysts, especially when operating under demanding conditions—such as high pressure, high steam partial pressure combined with low operating temperatures (approaching the dew point), or high-temperature and low-sulfur environments. Its outstanding advantages include:

• High Shift Activity & Excellent Activity Stability

• Strong Hydrogenolysis and Hydrolysis Capability for Organic Sulfur

• Superior Resistance to Hydration

• Excellent Carbon Burn-off Regeneration Performance
