Regenerierung von verbrauchtem FCC-Katalysator
Spent FCC catalyst is regenerated under net reducing conditions in a regenerator to minimize the migration of vanadium on the spent FCC catalyst particles. Net reducing conditions in at least the bottom 50% of the catalyst bed are maintained by using at least two spaced-apart air distribution grids...

| description | Spent FCC catalyst is regenerated under net reducing conditions in a regenerator to minimize the migration of vanadium on the spent FCC catalyst particles. Net reducing conditions in at least the bottom 50% of the catalyst bed are maintained by using at least two spaced-apart air distribution grids located in the lower 50% of the catalyst bed. |
