Activity of an aluminum-cobalt-molybdenum catalyst during fluidized bed hydrogenation

  • 35 Accesses

Summary

  1. 1.

    During high-temperature hydrogenation of an aromatized petroleum feedstock for producing naphthalene in a fluidized bed of microspherical aluminum-cobalt-molybdenum catalyst under a pressure of 20 atm and a temperature of 550°C the activity of the catalyst is maintained at a fairly high level for a short time (about 1 h).

  2. 2.

    For restoring the activity of a catalyst containing up to 10% coke oxidative regeneration can be carried out under an air pressure of 20 atm, at a temperature of 550°C. The air consumption is 13–15 kg/kg coke. After regeneration the activity of the catalyst is completely restored.
