VERFAHREN ZUR REGENERATION VON KATALYSATOREN FUER DIE GASPHASENREDUKTION VON AROMATISCHEN NITROVERBINDUNGEN

摘要

Catalysts for the gas-phase reduction of aromatic nitro compounds to aromatic amines are regenerated by treatment of the catalyst, at elevated temperature, with a gas mixture which contains oxygen, inorganic and/or organic amines and/or nitrogen oxides and, where appropiate, steam.
