摘要: A process and apparatus for fluidized bed regeneration of FCC catalyst are disclosed. Oxides nitrogen (NO x ) emissions from an regenerator operating in complete CO combustion mode, hydrothermal deactivation, reduced by reducing the average temperature. Dilute phase afterburning superheats entrained dilute region above bed. Cyclone separators recover superheated, preferentially recycle this to reactor, permitting cooler operation dense
