a Laboratory-scale FCC reactor. The reactor is an isothermal fixed fluidized bed, operating in batch mode. Gaseous products are collected at the reactor outlet. b Pilot/industrial-scale FCC process. The process takes place in an adiabatic riser reactor, which operates continuously. The gaseous products and deactivated catalysts are obtained at the riser outlet and separated in a disengager. The deactivated catalyst is regenerated through coke combustion. Both laboratory-scale and pilot/industrial-scale reactors follow the carbenium ion mechanism, with the reaction mechanism remaining consistent during scale-up.
