Abstract
Systems and methods for producing and using one or more doped catalysts are provided. One or more coked-catalyst particles can be fluidized in the presence of one or more oxidants to provide a fluidized mixture. The coke from the one or more coked-catalyst particles can be removed to provide regenerated catalyst particles within the fluidized mixture. One or more doping agents can be distributed to the fluidized mixture, and the one or more doping agents can be deposited onto the surface of the regenerated catalyst particles to provide a regenerated, doped catalyst particle.
