Abstract: The invention comprises methods of catalytically pyrolyzing plastics. Since it has been discovered that plastics provide insufficient coke to provide adequate heat during catalyst regeneration, heat-forming additives can be introduced into the methods. Systems and compositions useful in the catalytic pyrolysis of plastics are also described.
