  • PROCESS FOR DEPOLYMERIZATION OF SOLID MIXED PLASTIC
    Publication number: 20240052250
    Abstract: Systems and methods for processing a plastic are disclosed. The system includes a feeding device in fluid communication with a cracking unit. A feed stream comprising a plastic is depolymerized in the feeding device at a depolymerization temperature to produce a hydrocarbonaceous wax stream.
