Alumina Cobalt Molybdenum Catalyst
Features:
Uniform and stable components, high conversion rate, good low-temperature activity, high mechanical strength, good heat resistance, low steam consumption, high space velocity, etc., and various performances have reached the domestic advanced level.
Physical properties:
Appearance: Φ5x4~6mm black cylinder
Bulk density: 1.25~1.4kg/l
Specific surface: 75±10m2/g
Chemical composition:Copper, zinc, aluminum oxides and additives
Application
This product is mainly used for deep conversion of low-content CO in ammonia plants and hydrogen production plants. It can convert about 3% of CO to about 0.2%. The catalyst uses electrolytic copper and zinc ingots as the main raw materials, and adopts co-precipitation legal production.

Product usage and maintenance
·Normal use
Operating temperature: 170~260°C
Best temperature: 210~230°C
Operating pressure: normal pressure ~ 5.0MPa
Applicable airspeed: 1000~4000h-1
H2S in raw gas: ≤ 0.1ppm
Chlorine in raw gas: ≤ 0.03ppm
(Note: LB208 can be used at lower temperature or higher air velocity to increase the production capacity of the
device).
·Maintenance
a. Pay attention to stable operation during operation, prevent peroxide, prevent overheating, prevent liquid, and
prevent poisoning
b. Sulfur and chlorine are one of the common main causes of catalyst poisoning and deactivation. Effective
measures should be taken to minimize the content of sulfur and chlorine.
