    摘要: A method is provided for decomposition of chlorofluorocarbon to be decomposed and then disposed of. The process includes the following the steps of. A mixture of liquid chlorofluorocarbon substances to be decomposed (and then disposed of) and a liquid member are heated to a temperature of from about 500° C. to about 700° C. in order to produce a superheated vapor. The liquids member may be water, methanol, hydrogen peroxide, or mixtures thereof. The superheated vapor is maintained in a reactor for a sufficient reacting time in order to achieve decomposition of the chlorofluorocarbon in the mixture before passing through the reactor to a discharge outlet open to the environment.

    摘要: Disclosed is an economical process for treating a large amount of plastics waste in which thermoplastics, crosslinked plastics, thermosetting plastics or a mixture thereof can be continuously and rapidly degraded and converted into oil without sorting various types of plastics waste. According to this process, powdered plastics obtained by grinding thermoplastics, crosslinked plastics, thermosetting plastics or a mixture thereof is mixed with water to form a slurry, and a dispersing agent such as a water-absorbing resin, a water-soluble polymer or a surface-active agent is added thereto. The resulting mixed slurry is fed to a tubular continuous reactor where the powdered plastics is degraded under reaction conditions causing the water to be in or near its supercritical region. Finally, oil is recovered from the reaction product.

    摘要: A safe and efficient hydrothermal reaction apparatus is described herein. Decomposition or synthesis of object material is performed by the continuous passing of the material through a flow passage of multi-staged reactor units under turbulent flow conditions. The flow passage is formed by a curved or spiral piping. In each reactor unit, a hot plate block is included as a heating unit. The hot plate block and the curved piping are placed in an appropriate thermal contact relationship. A portion of the curved piping is freely supported, so as to accommodate stress caused in the piping under high-temperature/high-pressure conditions. A tank is provided for regulating or controlling the pressure fluctuation within the flow passage which may be caused by solids or powder present or occurring in the flow passage during high-pressure treatment. A portion of object material which has not been decomposed during the high-pressure treatment is again introduced or returned to the reactor for complete decomposition thereof after the addition of more solvent.
