SPN deoxidation catalyst of nitrogen and inert gas |
Use: |
SPN deoxidation catalyst is noble metal—oxide catalyst. t is mainly used in the dehydrogenation of nitrogen, argon, carbon monoxide, carbon dioxide, ethane, etc. It can dioxide at normal temperature with high activity, large capacity, high airspeed and reliable performance. |
Using method: |
A. Activation pre-processing before using1, Put the SPN-1 deoxidation catalyst evenly in reactor, and use nitrogen to extract all the air out of the reactor.2, Inject hydrogen (15~30%) and nitrogen blended, and airspeed is 150~200h-1. |
Using condition and technical parameter: |
Catalyst bed: | Height-diameter ratio:≥5 | Remaining oxygen in pure air: | 0.3PPm |
Use temperature: | Normal temperature~100℃ | Deoxidation capacity: | 12~25mg/g |
Using airspeed: | 5000h-1 | Bulk density: | 1.2kg/L |
Oxide density in raw material gas: | ≤1000PPm | Service time: | ≥2 years |
