This agent is mainly used in deep removal of oxygen from propylene in propylene polymerization process ,and also work as well as with other nonacidic gases or liquids . Deoxygenating agent Technical parameter: BH Appearance black cylinder Size D:5MM ;L:5MM Shape（kg/l） Cylinder Bulk density (kg/l) 1.0-1.2 Crushing strength (N) ≥98/cm Deoxygenate capacity (ml/g) ≥18 Outlet oxygen content (PPM) ≤1 Inlet oxygen content ≤1000ppm Best performance temperature normal Bearable temperature 400℃ Work-span ≥3years 　　The above mentioned data might be updated because of the technical development ,please contact us the latest one . Activation and re-activation 　　Both of them should be activated at its initiation . Input H2 contained gases at 100-200/h air speed ,heat the agent gradually and keep it at 200℃and 300℃separately for 1hour ,heat on and keep it at 400℃until the gases volume reach up to 1.5-2.0liter per gram agent ,stop heating ,input the gases on ,cool down and keep it air-proofed for ready . It should be re-activated when either being disabled .Input H2contained gases at 150-300/h air speed ,heat the agent at 4℃/minute,then keep it at 200℃and 300℃separately for 1hour ,heat on and keep it at 350℃for 3hours,stop heating ,input the gases on ,cool down and keep it air-proofed for ready .
