<p><P>PROBLEM TO BE SOLVED: To provide a new decomposition apparatus capable of taking out and recovering reaction liquid efficiently in a short time from a high-temperature and high-pressure reactor, in decomposition of plastic in a supercritical or subcritical state. <P>SOLUTION: The decomposition apparatus comprises: the reactor 1 that hydrothermally decomposes plastic in a supercritical or subcritical state; and a take-out part of the high-temperature and high-pressure reaction liquid 2 from the inside of the reactor 1, wherein the take-out part comprises (A) a cooler 4 that takes out and cools the reaction liquid, (B) a pressure regulation valve 5 on the outlet side or inlet side of the cooler and (C) a control means that detects the temperature of the outlet of the cooler and adjusts the opening of the pressure regulation valve such that the temperature of the reaction liquid becomes the boiling point or less. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
