US Patent 9371493 Low coke reforming

This process operates a continuous catalyst regeneration (CCR) system for reforming comprising the steps of: (a) introducing a coking additive selected from the group consisting of organo sulfur, organo nitrogen and oxygenate compounds into a hydrocarbon feedstock; (b) continuously introducing the hydrocarbon feedstock and coking additive of step (a) into a CCR reforming unit; (c) continuously introducing hydrogen into the CCR reforming unit; (d) continuously operating the CCR reforming unit to produce coke and a hydrocarbon rich, hydrocarbon stream; (e) continuously operating the CCR reforming unit to burn off excess coking additive; and (f) continuously recovering the hydrocarbon rich hydrocarbon stream.
