<p>PURPOSE:To reform plastic wastes into useful gases such as hydrogen gas and hydrocarbon gases by bringing the plastic wastes into contact with high temperature water including supercritical water in a reactor to gasify the plastic wastes. CONSTITUTION:A method for gasifying a plastics into useful gases such as hydrogen gas and hydrocarbon gases comprises feeding the plastics and pure water in a tubular reactor 1, inserting the reactor 1 into a crucible 3, mounting a cap 2, setting the reaction temperature to >=200 deg.C with a temperature controller 6, and subsequently bringing the plastics into contact with high temperature hot water including supercritical water in the reactor 1 for their reaction for a reaction time of 1hr. Thermoplastic resins such as polyethylene, polypropylene, polystyrene and polyvinyl chloride, and thermosetting resins such as polyurethanes and melamine resins can be used as the plastics.</p> |
