Two Step Process for Chemically Recycling Plastic Waste

A method for producing olefins and aromatics comprising;

• feeding a stream comprising plastics to a first pyrolysis reactor, wherein the first pyrolysis reactor comprises a mechanically or gravitationally induced moving bed;
• anaerobically pyrolyzing the stream in the first reactor at a temperature above 350° C.;
• preparing a raw, vapor product;
• wherein the residence time of the material in the pyrolysis reactor is at least 5 minutes;
• passing the raw, vapor product produced in the first pyrolysis reactor to a second reactor that comprises a fluidized bed fitted with a catalyst;
• catalytically reacting the vapor product from the pyrolysis with the catalyst in the fluidized bed reactor to form a product vapor mixture;
• and
• recovering olefins, or aromatics, or some combination thereof from the product vapor mixture.
