ABSTRACT:
A process for removing coke from particulate catalyst is disclosed, in which nitrogen oxides are formed during combustion of nitrogen-containing coke in an oxidizing atmosphere in the presence of a carbon monoxide combustion promoter in a lower portion of a fluidized bed, and the nitrogen oxides are reacted to form free nitrogen by introducing a vaporizable fuel into an upper part of the fluidized bed.
