ABSTRACT:
A continuous method for regenerating deactivated catalyst particles in a regeneration zone through which the particles are downwardly movable via gravity-flow. Particles initially are introduced into a carbon-burning section, flow therefrom into a halogenation section and then into a drying section from which they are removed from the regeneration zone.
